What is the best way to start a car in cold weather? How to start the engine in severe frost

16.04.2019

The low temperature becomes a serious test for the car. In severe frosts, everything that could previously be closed eyes appears. But the "iron horse" is able to move at any temperature, the most important thing is that the motor works. True, there are certain difficulties here, especially for vehicles with automatic transmission. So how do you start a car? Automatic in frost (automatic transmission) will only serve as a source of additional worries.

Cold and car

In order to take effective measures to start the engine at low temperatures, you need to know how the cold affects your " iron horse". Frost affects various components and mechanisms of the machine, as a result of which:

The capacity of the battery decreases, and it gives less discharge current. Accordingly, it is not enough for the starter to rotate the engine crankshaft.
The viscosity of the oil increases. And if in summer you can use grease with indices of 10 W and 15 W, then in winter you need to use 0 W or 5 W. This will reduce the resistance to rotation of the crankshaft and make it easier to start.
The volatility of gasoline decreases, as a result of which the formation of fuel assemblies worsens.

These reasons can be considered the main ones, although there are many others. But we will touch on them in the further consideration of the problem of how to start a car. Automatic in frost (automatic transmission) - not best helper in such a matter. The fact is that the automatic transmission has a feature that makes it difficult to start it in winter time. If ordinary cars the clutch at the time of starting the engine allows you to disconnect the transmission from it, then for cars with automatic transmission, the starter has to scroll through an additional automatic box filled with viscous oil.

Prevention that facilitates starting the engine in cold weather

If in a timely manner, before the onset of cold weather, a number of measures are taken, then their implementation will help start the car in the cold. First of all, you need to pay attention to the battery. If its service life has exceeded 3 years, then it is best to replace such a battery. In addition, before the start of the winter season, the battery must be charged using an external device. In fact, the car provides battery charging to the level of 75% of its nominal capacity.

And in winter, at temperatures below minus 20 ° C, this is clearly not enough. In addition, it is worth checking the density of the electrolyte. For the winter period, it can be made higher. But this procedure (checking the density and changing it) is best done in a specialized center.

Pay special attention to oil. It is advisable to use winter grades in winter, starting with the designation 0 W and 5 W. Thanks to special additives, they retain at low temperatures normal viscosity, which provides less stress on the starter and battery.

It is worth paying attention to the candles. If the car has driven more than 15,000 km with them, then it is better to replace them. Well, you need to check the condition of the battery terminals. If they are oxidized, then they must be cleaned, and all fasteners tightened. These violations lead to additional resistance in the discharge circuit, which reduces the starting current.

How to start the engine in the cold in a car with automatic transmission

Before considering how to start the engine in cold weather, it should be recalled that cold start equivalent to at least 150 km. But if it is necessary, then it is necessary. We'll start the car. We believe that initially it was not equipped with any additional devices to make launching easier.

Here, in principle, are the main ways by which you can start a car with automatic transmission in the cold. They are no different from those used when starting a car with a manual transmission. The only thing that cannot be done is to start “from the pusher” or with the help of a towing vehicle. This is fraught with damage to the automatic transmission. You can get more information about starting the engine in cold weather by watching the video:

Winter is a demanding examiner for both the driver and the car. And first of all it concerns the launch vehicle. It should be noted that cars with automatic transmission, with all their advantages in similar situation give owners more trouble. But nevertheless, they successfully start in the most severe frosts.

WITH sharp drops temperature and just a cold snap, many car owners are faced with the problem of starting a frozen car.

The fact that the cars do not start, according to experts, is often not the fault of the frost, but the drivers themselves. After all most cars are designed to work down to minus 30 degrees below zero ...

The first thing experts recommend to start with is to replace the summer or just old oil that quickly thickens in the cold with a new one, preferably “synthetics”. Eg, oil index 0w or 5w less viscous at low temperatures Oh. It is also advised to replace filters and change old or dirty spark plugs, if necessary, replace the battery.

Even when it is not very cold, problems arise for a car that has stood for several days without moving. Each vehicle may have its own reason for this “hibernation”, but there are several similar problems that many people experience at low temperatures.

We will not cover all, but most typical problems with engine start. This may be a small single malfunction, or it may be a whole range of problems that need to be addressed. If you properly maintain your car, follow the requirements of the operating instructions, then some of them simply will not affect you. But if you still have difficulties, then here are the most common solutions:

1. Weak battery

Cause:

The battery may not hold a charge well due to age (more than 3 years), internal defects or misuse.

Signs:

The starter does not turn the engine at all or turns unstable, while the lights on the instrument panel are dim.

Solutions:

If the battery somehow reacts to attempts to start the car, then you can try to turn on the low beam headlights for a few seconds. This will help "wake up" the battery, and on the next try, it will give out the required amount of energy.
Check the battery terminals: Dirt or oxidation often breaks the connection. Cleaning them can restore normal current flow.
Start car with mechanical box pusher gears.
"Smoking" from another car.
If you have time, you can remove the battery and take it to a warm place to warm it up.
Radical measure - installation new battery, preferably larger capacity.

Prevention:

Remove the battery and take it to heat for the night (this is what most car owners of the Siberian and Ural regions do).
Install a system that will monitor the temperature of the engine, and when it drops to the set level, the electronics can independently start the car and maintain the "working" temperature.

Rules for operating the battery in cold weather:

Firstly, even before the onset of cold weather, it is imperative to check the electrolyte level and its density. For a battery suitable for use, the density of the electrolyte must be at least 1.25 cm3. (ideally 1.27 g / cm 3), and the voltage should be at least 12.6 V. Special attention should pay attention to topping up water: you need to top up only distilled water. After topping up and insufficient density electrolyte, the battery needs to be charged. If the charger allows you to adjust the charging current, then it must be set within 4-5 amperes.

With decreasing temperature, the charging efficiency at constant voltage decreases due to an increase in the internal resistance of the battery. Therefore, usually the degree of charge of the battery in winter is 70-75%, with a voltage in the terminals of 13.9-14.3V with the engine running and the dipped beam on. It is because of this that experts advise periodically (at least once a month) to charge the battery from a stationary charger and at a positive temperature, having previously measured the density of the electrolyte.

Also, in winter, it will not be superfluous to heat the battery with heat from the engine, in order to better charge it from the generator. To do this, it is advised to close the part of the radiator (on the side where the battery is located) from the oncoming cold air flow. In addition, at temperatures below "-30" degrees, to ensure a normal engine start, heating the battery is simply necessary. To do this, you can either take it into the heat (troublesome, of course, but also an option) or heat it directly at the place of its installation. Also, to facilitate starting the engine from a cold battery, you can use the heating of engine oil and fuel. But perhaps the easiest option is injection special liquid into the carburetor, which makes it easier to start the engine.

Let us also draw your attention to the fact that the battery charging time is measured by the density of the electrolyte, which indicates the degree of battery discharge.

The degree of discharge of the battery can also be checked with a tester. We note right away that such a check should be carried out after an hour of "idle" after turning off the engine and consumption sources.

Recall that the degree of charge battery checked in the following way:

electrolyte density, g / cu. cm 1.27 1.23 1.19

voltage not lower, volts 12.7 12.5 12.3

state of charge 100% 75% 50%

Further, the battery capacity (for example, 55 ampere-hours) must be multiplied by the missing percentages (for example, 50%). The result is the required number of ampere-hours (in this example 22.5). Then we divide this figure by the force charging current, reduced by about 2 times (taking into account the coefficient useful action) and get the charge time.

To reduce the negative effect of cold on the battery and on starting the engine in winter, it is also recommended not to neglect the following:

don't let long work included consumers on the car when the engine is not running;

"mass" wire from starter battery it is useful to additionally connect to the engine in order to reduce voltage losses at the starter when starting the engine. This is done for the reason that voltage transitions from the terminal to the body, and from the body to the engine, reduce the voltage and lead to a loss of power consumed from the battery;

from time to time to check the absence of "leakage" of current from the battery to different segments electrical equipment. To do this, you can turn off the battery - remove one tip - if the parking conditions of the car allow for such actions;

control the tension of the alternator drive belt, which ensures the full return of energy to power the switched on consumers and the battery itself;

during warming, before starting the engine, remove moisture from the surface of the wires, as it favors current leakage from the ignition coil.

2. Excessively thick engine oil

Cause:

Due to the low temperature, the oil "does not let" the moving parts of the power units. Most often this happens if the oil is old and heavily contaminated, does not meet the operating temperature conditions, or is simply of inadequate quality.

Signs:

A fresh battery and a serviceable starter turn the engine with great difficulty, and a dense consistency is visible on the dipstick for oil.

Solutions:

It is almost impossible to quickly change the frozen oil. You need to either wait for warming, or warm the car in a warm room. With a manual gearbox, you can “drag” the car in tow for some time so that the shaft turns.

Prevention:

Monitor the quality of the oil by buying branded brands in trusted places with numbers in index 0W or 5W, synthetics for new cars and semi-synthetics for cars with mileage over 100,000 km. Before pouring new oil, the canister with it can be left in the cold. If it has retained its consistency - everything is in order, but if it has thickened a lot and does not splash (this can be understood without opening the package) - return it to the seller.
As a last resort, before long-term parking, when the car can cool down completely, immediately after the engine is turned off, you can pour 100–200 ml of gasoline into the crankcase. The fuel will dilute the oil and the engine will spin. This procedure is harmless enough, but you should not abuse it. Especially undesirable "dilution" for modern engines, which require various lubricating, cleaning and antioxidant additives. Specialists treat these tricks as physicians treat healers. The chances of starting the engine in such ways are equal to the chances of ruining it.

Ignition system misaligned

Cause:

Due to problems in wiring or parts high voltage does not reach the candles (or comes in a very weakened form), and a spark is not produced.

Signs:

The starter turns, the shaft turns, but the car does not start. The check is divided into three stages: a spark in a distributor, a spark in a candle and the candle itself. It is necessary to pull out the central wire from the cover of the distributor and bring it to some unpainted part of the mass of the car by one centimeter. When the key is turned in the ignition, a spark can be seen near the wire and a characteristic clicking sound can be heard. If they are not, then the problem is in the coil or high-voltage wires. The current may also not reach the candles. To check this, you need to remove the wire from any candle, bring it to the mass by 5 mm and again try to start the car. The spark will be weaker and quieter, but you can see it. This procedure is best done with gloves or by wrapping the candle wire in an insulating cloth. If there is voltage, then the problem is in the candles, if not, then in the cover of the distributor, slider or wiring. Wiring problems can be detected if you start the car in the dark - then all the "weak" places glow from small sparks of bad contacts.

Solutions:

In relatively high humidity, spraying can help. high voltage wires special water-repellent aerosol.
Replacing or calcining candles, replacing a distributor, high-voltage wires or an individual coil (depending on the car model).

Prevention:

Before the cold weather in the service, adjust the ignition system, this will also have a positive effect on fuel consumption.

4. Bad gasoline or its supply is broken

Cause:

diluted gasoline. If the fuel is diluted with lower quality, then this is reflected in the power of the car and the pollution of its parts. But if gasoline is simply mixed with water, then in the cold it and condensate freeze. Condensation can disrupt the entire fuel system or one of its sections - from the filter to the fuel pump.

Signs:

All systems work well, but the engine does not "seize", while the candles are dry, and the exhaust pipe smells of unburned gasoline or there is no fumes. If you keep an open fire over a small spot of gasoline at a distance of 5-6 cm, and it does not ignite, then there is too much water in the fuel, and it does not allow carbohydrates to evaporate. The unscrewed candle is either completely dry (gasoline is not supplied or there is none at all), or filled with gasoline

Solutions:

Use so-called "gasoline dryers" according to the instructions, if the problem is only a fire. If this does not help, then you need to wait for warming or warm the car in a warm room. After warming up, if possible, drain bad gasoline and clean / dry all elements of the system.

Prevention:

Refuel at trusted gas stations.
If there is any doubt about the quality of the fuel, then use additives that bind water to the gel, at each refueling.
How more gasoline in the gas tank, the fewer surfaces on which water can condense. Accordingly, in winter it is better not to drive with a half-empty tank.
Filter installation fine cleaning with a sump that will collect excess water. The closer it is to the gas tank, the better.

4. Everything works, but the spark plugs are flooded

Cause:

The spark plugs are so dirty that the spark cannot get through to the ignition chamber. Or until other systems worked, gasoline was supplied to the combustion chambers and “filled” the candles, representing no air mixture, but a liquid.

Signs:

The unscrewed spark plugs are completely covered with gasoline. It is best to check them before the battery is completely dead. The exhaust smells like unburned gasoline.

Solutions:

If the situation has not reached a critical level, then you need to temporarily stop trying to start the engine. Wait a few minutes for the petrol to "drain". Turn the engine with the starter for a few seconds, fully depressing the gas pedal, to "ventilate" the cylinders and try again. The driest cylinders can “grab” and pull the rest along with them.
Cleaning of candles, their calcination or replacement. Unscrewed candles can be cleaned with a simple toothbrush and a modern cleaning agent. The main thing is not to get carried away and not damage the insulating layer. Candles can be ignited on the burner of the stove until they cannot be taken by hand. The hotter the spark plugs are when they are screwed into the engine, the better.

Prevention:

When the car is started for the first time, do not immediately press on the gas pedal. Let it first "grab" in the standard starting mode.
Periodically check the function of the glow plugs.

5. "Summer" diesel fuel

Cause:

The jelly-like state of the fuel interferes with its pumping, and the paraffin flakes formed from the cold clog the fuel system.

Signs:

The starter turns, but the engine does not catch. There is no fumes from the exhaust pipe.

Solutions:

Use autochemistry type "quick start" according to the instructions.
Shed hot water nozzles, fuel filter, pump high pressure, avoiding contact with the starter and alternator, and try to start again.

Prevention:

Refuel with "winter" diesel fuel and, in case of doubt or expected cooling, add anti-gel or depressant additives.
Before starting, turn on the ignition several times, warming up the candles, but do not start the engine.
Install the fuel filter heater.

Globally solve the problem with starting the engine in cold weather can installation preheater.

They can also help start the engine. special aerosols, which are injected into intake tract car.

Often, neither the first nor the second time the car hard frost does not start, but "grabs" for an increasingly longer period. Patiently repeat the starter scrolling for no more than 10 seconds until the car starts.

Sometimes the reason that the car will not start can be condensate in exhaust pipe . It can be removed simply by physical cleaning.

If the car has a manual transmission, then it is better start it with the clutch depressed. In this case, only the engine crankshaft rotates, and the gears of the gearbox remain in place, which reduces the load on the starter.

Before leaving the car for a long time, dry the brake pads and do not leave the car on the "handbrake". brake pads can freeze to disks (with drum brakes the situation is even more unpredictable), and then with all the systems running, the wheels simply will not spin. In order for the car not to roll away, it is better to leave the car in gear (manual transmission) or in the parking lot (automatic transmission), and with a large slope, place stops.

On many new foreign cars, the probability of starting is associated with the level of starting enrichment of the mixture, which is determined by electronics. This is due to the fact that in Europe "winter" gasoline is used with great content light fractions. Some vehicles may require longer cranking by the starter.

Do not use remote autostart from the alarm. Electronics does not understand the problems of a cold start, so it can land the battery and fill the candles.

Diesel engines: turn on the glow plugs 2-3 times by turning the key and wind up better with one attempt - turn the starter until it starts.

After the car has started, do not turn it off for a while. You do not need to immediately turn on the stove, heating, music and lights - this is an additional load on the battery. For the first few kilometers, it is better to drive at speeds up to 40 km / h, so that the components and assemblies gradually warm up.

Freezing locks and other troubles

With the onset of frost, it is recommended to take a small can of WD-40 with you in the morning (with a pocket capacity of 0.1 l) in order to open a jammed car door if necessary. After all, the water that can accumulate in the castle during the night, by morning, as a rule, freezes and does not allow you to open the car door. Many in this situation try to warm the castle with matches or a lighter. Although in fact it is much easier to use the above canister, which usually comes with a tube through which the de-icer is introduced into the keyhole. After several turns of the key in the lock, the latter remembers its original functions. The "highlight" of the use of such a liquid is also that it not only destroys ice, but also prevents its further formation. Freezing of locks can be generally avoided by injecting this liquid into the keyhole before the onset of frost and repeating this procedure every 2-3 weeks.

In addition to the lock, nipple caps can also freeze. The saddest thing in this situation is that this can only be detected at the moment when it becomes necessary to pump up the wheel. It turns out that this is simply impossible to do, since it is impossible to unscrew the nipple cap.

You should also process the door and gas tank cap (you can use the same WD-40), since freezing does not bypass these parts of the car. It happens that when arriving at a gas station, the driver leaves with the same tank with which he arrived there. Just for the reason that the gas tank cap froze "tightly".

Zimushka-winter is already clearly on the threshold. Night frosts are clear proof of this. It’s easier for a person: he dressed himself, drank warm tea or coffee, or warmed himself in other ways, and only the owner can take care of it. We often find it difficult to start the car in the cold. Let's consider in this article what needs to be done if this trouble "set you on the bandwagon" at a completely inopportune time.

In addition, we will help you figure out how to additionally help your beloved car even before the onset of severe frosts, and thus minimize the occurrence of problems.

How to make it easier to start the engine in the cold

It should be taken into account that these actions must be done constantly during the period of low temperatures.

Take the battery overnight in a warm room. This option has a serious "plus", but the "minus", of course, is in the weight of this device. Wearing it daily, especially if you live far from the parking lot, not everyone can.
Before starting the engine, press the high beam button several times. A slight heating of the motor is provided.

But these are, in principle, half measures, let's consider a more detailed master class on how to start a car in cold weather with the least effort:

Consider alternative options who recommend experienced drivers, specialists and . Why is it important? It is not always possible to remember the sequence of actions suggested above, so additional tips on how best to start the engine in cold weather will always come in handy:

Press the gas and at the same time turn on the ignition for a few seconds: the combustion chamber is purged.
Then briefly start the starter to prevent it from overheating and, further, as usual.

A good option (if you have the time) is to warm up the battery in a warm room. Additionally, it does not hurt to recharge it: the features of this device are that at low temperatures it loses its properties. At present, it is not a problem to purchase a household charger and, thus, save yourself from a number of problems, especially in cold weather. This advice applies more to gasoline engines.

Universal way

"Help a friend" is a great way if the battery is "dead" and there is no way to revive it. In another car with normal battery disconnect the terminals and connect both power sources using thick wires. Observe the principle: strictly pros and cons among themselves. Otherwise, winter fireworks are guaranteed.

Within 10 minutes, the weaker one is recharged. At the same time, a short-term inclusion of the engine of a “healthy” car will help to enhance the effect. In principle, this time is quite enough to achieve a result.

After that, it is necessary to turn off the engine and, without removing the wires, we start problematic engine, as a rule, he "comes to life". But it is important for at least 5-10 minutes, depending on the external temperature, to warm up the engine. After that, the "heart" of the machine is turned off, the wires are disconnected.

What to do with a diesel engine

To begin with, everything is the same as with a gasoline engine: warming up or recharging the battery. As an option that is applicable to any car: transportation to a warm garage. , designed for low temperatures, is the best prevention Problems.

Old-fashioned method: pour boiling water over fuel tank And . Alternatively, use ordinary hair dryer for hair.

Winter is a real test for motorists. Cause run cold engine at negative temperatures it is much more difficult than in summer. Under such conditions, the viscosity of the oil changes, and if we talk about diesel vehicles, and the viscosity of the fuel. The starter needs more power to turn the engine over the flywheel ring. Therefore, the load on the battery also increases. Often, inexperienced motorists simply drain the battery in an attempt to successfully start the engine. As a result, such a machine is completely impossible to start. But how to properly prepare for starting the engine in cold weather? We will talk about this in our today's article.

Battery voltage

If the car has stood outside for a long time or the air temperature has dropped below -20 degrees, it is worth checking the voltage in the battery before starting the diesel engine in cold weather. In cold weather, the density of the battery electrolyte may drop. The capacity of the battery also decreases. As a result, it is very difficult to start the engine in cold weather. After turning the ignition key, the starter will lazily turn the flywheel. And on the second or third attempt, it will refuse to work at all.

In order not to sink the battery to zero, it is worth checking its voltage before starting. For a successful start given parameter must be at least 13 volts. If the indicator is less, it is worth charging the battery.

How to increase battery density

An important characteristic in any battery is the density of the electrolyte. If it is lower than 1.27 grams per cubic centimeter, such a battery will be useless in winter. The car does not start in the cold - what to do? To bring the battery back to life, it is worth replenishing the electrolyte level. It is poured through special holes on the lid (there are only six of them). After that, charging is carried out with a minimum current strength for three hours. Then re-measurement is made with a hydrometer. If the figure is 1.27-1.28 grams, such a battery will start the engine in cold weather.

Oil

An important characteristic that determines the ease of starting in winter is the viscosity of the oil. If the annual mileage of the car is more than 20 thousand, experts recommend changing it according to the season. There are several types of motor oil:

Summer.
Winter.
All season.

All of them are labeled with a two-digit SAE viscosity value. It is considered that the most best oil is what the manufacturer recommends. But winters are different, so sometimes you can deviate from the manufacturer's recommendations. Winter oils are marked with the letter W.

If the average air temperature in a given season is from 10 to 25 degrees below zero, you should focus on products with a viscosity of 0W to 10W. You can choose both synthetics and semi-synthetics. Oils with this viscosity will provide easier starting of the engine in cold weather. If the winter is warmer, products with a viscosity of 15W can be used. But remember that the lower this figure, the less oil density. Accordingly, on older engines, it can simply go through worn seals, gaskets, or into the combustion chamber through the rings. Therefore, it is not necessary to significantly reduce this indicator.

Compression

This parameter should be especially monitored by owners of old used cars. On gasoline engines, the compression ratio should be at least ten atmospheres. On diesel - from twenty and above. If the compression is lower, the engine will be difficult to start. And if in the summer it starts on the third or fourth attempt, then in the winter the battery cannot have enough strength for such a long start. The measurement is made using a compression gauge. It is installed in place of the unscrewed spark plugs. After installation, you need to scroll the crankshaft 2-3 times with the starter. And so for each cylinder. Indicators should not differ by more than one atmosphere. If the compression is weak, such a motor needs to be repaired. Otherwise, in cold weather, the car will not start.

But it often happens that the engine does not start with a good battery and with normal compression. In winter, the driver has no right to make a mistake. Therefore, you need to know how to start the engine in cold weather on the first try. We will talk about this below.

How to start the engine in the cold correctly? If you have petrol car, do not immediately start the internal combustion engine after turning on the ignition. You have to wait until electric pump pumps fuel into the rail. This will take no more than three seconds. But it is these seconds that can save when starting the car in the cold. So, turn on the ignition and wait until the pump pumps liquid. This can be determined by the sound. During operation, the pump will emit a characteristic hum in the rear of the car. When it is silent, you can start.

A useful operation would be to warm up the battery. This can be done without removing it from the vehicle. It is necessary that the load go to the battery - this will help activate the electrolyte inside. To do this, enable high beam for ten seconds. However, remember that all electrical appliances must be turned off when starting. The slightest load on the battery will significantly aggravate the work of the starter. If the vehicle is equipped with a manual transmission, it is recommended to depress the clutch pedal when starting.

What will it give us? The oil in the manual transmission is very thick (viscosity 75w90), so when the flywheel rotates, the starter will partially work to rotate the gearbox parts. To reduce the load on the battery, which will give us starting current, we squeeze the clutch pedal to the floor. This will reduce the risk of an unsuccessful start of the internal combustion engine.

It happens that during a cold start on a gasoline engine, candles are flooded. As a result, it is very difficult to start the engine. Of course, a more correct solution is to dry them in a dismantled state. But you can dry the candles without twisting them. How? To do this, while rotating the starter, you need to press the gas pedal all the way. This operation will increase the purge of the combustion chamber from excess fuel and allow you to successfully start the engine.

But these tips only apply to gasoline engine. But what about the owners of "solid fuel" cars? For them, we have selected a few useful tips.

The diesel engine did not start in the cold. What to do

On such engines there is one significant problem. Diesel thickens at -5 and below. In view of this, the purchase of antigel will be a useful acquisition.

This is a special additive that liquefies diesel fuel. It is added to the tank in small proportions. In winter, the fuel thickens, turning into paraffin. Because of this, the fuel is not able to penetrate through the fine pores of the filter. But there are situations when the fuel thickens in the injection pump itself. In this case, it is necessary to carefully pour boiling water over its body. Try not to flood the generator and starter. Keep trying to buy winter fuel at the gas station or use the additive in the tank in advance.

Do I need to warm up the engine

This question causes a lot of controversy among motorists. And if in the summer you can still refrain from warming up, then in winter this operation is required. Warming up the engine in frost will prepare all systems and mechanisms (take at least the same oil that thickens with a drop in temperature) for work. But you need to do it right. Do not immediately turn on the cabin heater. So you spend a lot of time warming up. And here is the inclusion lighting fixtures and other "electricians" will be useful. This will increase the load on the generator, and, accordingly, on the crankshaft. This will allow the engine to warm up faster. operating temperature and the battery is fully charged.

Does the engine need to warm up for a long time? Experienced motorists do not advise "lubricating" the motor for 15-20 minutes or more. This is bad for the engine. Five minutes of work is enough for Idling so that the engine warms up to a minimum of +60 degrees. After that, you can confidently carry out the movement. If the car is equipped with automatic transmission, during this period (while the engine is idling), all modes should be switched in turn. So we will warm up the ATP liquid in the box and save its resource.

Conclusion

So, we found out what to do if the car does not start in the cold, as well as how to prepare it for a cold start and movement. Good battery and liquid oil are the main conditions for an easy and successful start-up of the internal combustion engine.

Winter is the time at which cars begin to "act up", not wanting to start when necessary. Engine freezing and oil solidification are common at sub-zero temperatures. If we talk about a car with a manual transmission, which has suddenly run out of battery, you can take it in tow, but for cars with automatic transmission, everything is a little more complicated, since it is forbidden to tow them. We will describe several options for starting a car with automatic transmission in cold weather, and what to do to avoid such situations from happening again.

Ways to start a car at sub-zero temperatures

Start the engine of the machine with automatic winter frosts becomes a difficult task if preventive measures are not taken in a timely manner to prepare the car for the appropriate weather conditions. An automatic transmission (if it is not ready for operation in winter) complicates the engine plant. It also complicates the operation of the engine and thickened oil, which interferes with the normal rotation of the automation shafts. It is important to consider that the manual transmission can be turned off when the clutch is depressed, and the machine cannot be turned off like that. That is why timely preparatory measures are so important in the case of transferring a car for the winter period.

So, so that your car does not freeze, you need to prepare.

Prepare your car for winter

To prevent freezing of your automatic transmission vehicle, it is necessary to prepare for operation in winter.

Replace engine oil for better quality, corresponding to operation in winter weather conditions (pure oil- easier to start the engine).
Purchase and install special additive accelerators. Facilitate the launch of automation can fuel additives improving the ability to ignite frozen fuel.
Check the condition of the battery, which should be replaced if it is unstable or has been used for three years or more.

Take care of a garage (however simple and unheated) for your car. Its presence will help your car to winter without freezing.

They did not have time to prepare the car for winter, and the engine does not start, then the automatic transmission should be reanimated and the battery capacity should be increased. To do this, you will have to use some proven methods.

How to start a car in winter?

Switch on the dipped headlights for a short time. This action will warm up the electrolyte located in the battery, increasing the capacity of the battery. This should increase the efficiency of cranking a frozen engine.
Inject a few grams of ether into the intake manifold, which is designed to make it easier to start the engine in the cold season.
Start the engine using the starter charger. In its absence, you can "light up" at a nearby vehicle.

If all else fails, then you have to walk / drive on public transport and warm up the engine with a blowtorch. When your automatic car is warm, you need to charge the battery at home, replace the candles with dry ones and, if you have not already done so, prepare the car for winter operation (check/replace the battery and change the oil).

Take care of yourself and your car:

timely monitor the condition of the automatic transmission, the quality of the oil and the operation of the battery,
buy good fuel
try to buy / rent a garage for the car,
never put your automatic car in tow,
when freezing, use proven methods for warming up.

Let your car always be on the go and never let you down in particular important points haste. Everything is in your hands - an easy factory in winter and good roads!

Evil frosts affect all living things and not only. Car owners know firsthand how difficult it is sometimes to start your “swallow” at sub-zero air temperatures. Numerous attempts to traditionally start even the most trouble-free engine often end in failure and complete discharge of the battery.

To eliminate such consequences, you need to know a few simple secrets and tricks on how to properly start a car in cold weather.

Why is it hard to start a car in winter?

To understand the specifics of starting a motor in a cold season, you need to understand the main reasons that complicate this process. Most often, difficulties arise due to such phenomena:

freezing of the battery;
increased viscosity lubricants;
formation of condensate in fuel systems;
wiring oxide;
coolant problems.

The chemical elements of the battery at sub-zero temperatures lose their activity. Therefore, the lower the thermometer falls, the slower all lead-acid reactions occur.

At an air temperature of -18°-20°C, the actual output of a fully charged battery is about 40% of the total resource. And the performance of a "run down" battery in severe frosts is generally reduced to a minimum. Therefore, at night it is better to bring the battery into a room with positive temperatures.

Lubricants at sub-zero temperatures noticeably increase viscosity, which increases rotational resistance crankshaft and other mechanisms. Consequently, at the starting moment, the load on the barely “live”, frozen battery increases greatly, as a result of which it quickly sits down. Usage winter oil significantly reduce the resistance of rotating mechanisms, which will increase the performance of the starter.

Another serious problem can be the formation of condensate in the nodes of the fuel system. Water droplets contained in gasoline or diesel fuel, when frozen, create plugs that prevent the normal flow of fuel into the combustion chambers. This phenomenon can be prevented by using winter fuel and special additives to it. It is advisable to refuel only at proven gas stations.

Video - what devices help to start a car in cold weather without problems:

Oxide of terminals and contacts most often occurs with frequent temperature changes. When the engine is off, the wires take on the temperature environment, and during operation of the vehicle heat up. This leads to oxidation and deterioration of the contact strength, which can also affect normal starting.

To prevent such a situation, it is necessary to periodically clean the terminals with a rounded file, and perform all fasteners with high quality.

Video - possible problems after an incorrect start of a car in winter:

The coolant has a working temperature limit, overcoming which it can freeze. Rotation of the starter in such cases can lead to breakage of the pump blades and failure of the cooling system.

The operation of a car with such a breakdown becomes unacceptable. To avoid such consequences, specifications fluid used must comply with climatic features region.

You can achieve the goal as quickly as possible by adhering to a certain sequence of performing all actions.

If the battery has been outside for a long time, then before starting the engine, it is necessary to turn on all the electrical equipment of the vehicle for a few seconds (high beam, stove, alarm etc.). A sharp load on the battery will make it "wake up" and begin to interact with all its elements.

A few presses of the gas pedal should ensure the supply of fuel to the cylinders. In machines equipped with manual choke, you can partially or completely close the damper by pulling the handle towards you.

You need to start the car neutral gear with the clutch depressed. This will save energy for turning the shafts and gears of the gearbox.

All attempts to start the engine should be short (3-5 seconds) with half-minute breaks. Prolonged rotation of the starter can quickly drain the battery, fill the spark plugs, etc.

Upon reaching the goal, the engine should be warmed up at medium speed. Release the clutch pedal smoothly after 15-20 seconds.

Proper diesel start

The main problem with diesel engines is fuel freezing. Adding kerosene to the fuel at the rate of 1: 5 will solve this issue. And you can simplify the start of a diesel engine by adhering to the following algorithm of actions:

Setting the key to the penultimate position is necessary to warm up the glow plugs. Performing this procedure three to four times will “wake up” the battery.

The choke (if any) should be fully set to "minimum".

After depressing the clutch, you can start turning the starter. The duration of its rotation for a diesel engine is approximately 10 seconds. And in cases where the car shows signs of "life" it is best to turn the starter to the bitter end.

It is necessary to ensure the supply of fuel by smooth pressing the gas pedal. It is important not to overdo it here, since cold diesel fuel is poorly sprayed and can flow into the combustion chamber in a jet, which is very undesirable.

If the engine starts, it should be warmed up at 1500 rpm. Keep the clutch pedal depressed for about half a minute. If you release it immediately, then there is a risk of stalling.

Video about starting a diesel engine in cold weather:

Current consumption at starting torque diesel unit one and a half to two times higher than that of a carburetor, so you can start it only if the battery is well charged.

Features of injection engines

It is necessary to start such cars in the same way as carburetor ones. Distinctive feature is that the injector initially requires three ignition on / off. This procedure will allow the fuel pump to fill the fuel line as much as possible. In this case, the gas pedal should be operated very moderately.

Video - how to start a car in severe frost:

If the car flatly refuses to start, then with the help of a medical syringe you need to inject one cube of ether into the rubber band of the air pipe. The hole must be drilled as close to throttle assembly.

Important! This method should be resorted to only in cases of emergency, since an overdose of ether is fraught with serious damage.

How to start a car with automatic transmission

The main factor influencing the technology of starting an engine at sub-zero temperatures is not the type of gearbox, but the type of fuel consumed. Starting cars equipped with automatic transmission must be guided by the rules suitable for a particular type of engine (carburetor, diesel or injector).

The only feature of cars with automatic transmission is that they do not have a clutch pedal, so you do not need to squeeze anything extra. In addition, in cases of unsuccessful attempts, you can try to start a vehicle with a manual transmission from a pusher. Cars equipped with an automatic transmission do not lend themselves to this method.

What to do if the battery is dead

If the battery charge was not enough to rotate the flywheel, you can try to start the car by towing or using the crank, or you can use the battery energy of a nearby vehicle - “light a car” (you will need special starting wires).

If there is no urgent need to leave, you can try to restore normal work your battery:

The battery must be brought into a warm room and allowed to “thaw”. It is highly undesirable to use heating devices (hair dryers, heaters, etc.) to speed up the process.

After acclimatization, the battery must be unscrewed top covers jars and check the presence of electrolyte in them. If its level is low, then it is necessary to add distilled water to the jars. Using an aerometer and other devices, check and correct the density of the electrolyte.

Let the battery charge for several hours.

Attention! When servicing the battery, a set of safety measures must be strictly observed, and all procedures must be carried out in a certain sequence.

A number of preventive actions and timely Maintenance car will help to simplify the start of the engine when the thermometer is negative.

Important! Warming up the engine and fuel system components using open sources of fire is unsafe. You should also not pour boiling water over the motor, since in severe frost the metal may burst, and microcracks may form in the block. Only water at room temperature should be used for heating.

The sign itself "Stopping is prohibited" and the area of the sign - the topic of the rules traffic, with answers for which it is allowed a large number of mistakes in the exam.

Requirements to winter tires changed, so their choice should be treated very carefully.

How to start a car in cold weather?

winter period operation is the most difficult not only for the owner, but also for the car itself. Especially depressing are the problems with launching your “iron horse” on a frosty morning after a sharp cold snap. And in order to ease winter launch car, you need to prepare it properly for operation in the winter season, as well as know some tricks on how to start a car in winter.

Preparing the car to start the engine

Preparation of any car for operation in the winter should begin with the accumulator. To do this, clean the terminals, then carefully tighten all the nuts and their fasteners. If your car's battery is old, it's best to replace it with a new one. When choosing a new battery, you should give preference famous brands with large capacity. Try to avoid cheap Chinese, as well as counterfeit Russian batteries. It is also necessary to regularly wipe the surface between the terminals with a dry cloth. On the starter, check the contacts of the supply wires, as well as the tightness of the tips that protect these contacts. When trying to start the engine, it is necessary to avoid running it for a long time so as not to burn it. Attention should also be paid to the fact that prolonged rotation of the engine by the starter has an extremely negative effect on power unit car, especially if it is injection and with electronic control. It is necessary to check the condition of the high voltage wires. It is necessary to pay attention to the absence of cracks in the insulation. If cracks are found, the entire wire should be replaced rather than trying to fix them with water repellent sprays. You also need to check the cover of the distributor. You should not use used or Chinese wires, since such a replacement will not be of any use. The condition of the oil in the gearbox should be checked, if necessary, it must be replaced. Pay special attention to the fuel level. The tank must be more than half full. This is necessary so that the water that accumulates at the bottom does not get inside fuel line and did not freeze there at low temperatures.

How to start a car with manual transmission

The main rule that allows you to solve such a problem as starting a car in cold weather is to turn off all consumers of electricity. These include: headlights, heater fan, air conditioning, audio system, heating rear window. If the battery is cold, then in order to warm it up, you need to turn on the headlights for 30 seconds. Then turn the engine with a starter, but not starting immediately. After that, you can begin the main attempts to start the engine, while squeezing the clutch. If the first attempt fails, you must wait a pause of 30-40 seconds. You can then try to start the engine again. Do not touch the gas pedal, as the injection system itself must provide required amount fuel. So you need to make no more than 5-7 attempts to start with pauses between them of 30 seconds. If these methods did not help and you do not know how to start the car in winter, in such a situation, then moisture should be removed from the high-voltage wires. To do this, use a Wd-40 spray. Having connected the wires to the battery, you need to ask the other driver to “light it up”. Most importantly, do not forget to pause between attempts to start. If this method did not help to start the engine, you can resort to using a tug. In this case, it is worthwhile to agree in advance with the driver of the towing vehicle about the signals, and then turn on the second or third gear. Once the engine starts, do not let it stall. To do this, gently press the gas pedal. Then you need to immediately squeeze the clutch and shift into gear. Now the motor should warm up. To do this, you need to increase the engine speed to 1100-1500. So the engine can warm up much faster, and the battery can be charged.

How to start a car with automatic transmission

Owners of vehicles with automatic transmission need to prepare for winter operation more thoroughly. If your car battery lasts more than three years, you should replace it with a new one. In order to facilitate starting the engine in the winter season, the industry produces special fuel additives. They significantly improve the ignition properties of cold gasoline. Do not forget that gasoline loses its properties when the ambient temperature drops below -32 degrees. Starting in the morning in severe frost should start with turning on the dipped headlights for a couple of minutes. After that, you can start the engine. If the attempts are unsuccessful, then it is worth injecting a small amount of ether into the suction manifold. This ether is designed specifically to facilitate starting the engine in the winter season. If, after all the attempts described above, it was not possible to start the engine, then do not lose heart, you may still be able to start the car. You can get help with this starter-charger. In any case, it will be necessary to restore the capacity of the battery, and only after that you can try to start the engine on a car with an automatic transmission.

If you are the owner of a car with an "automatic", then you should not resort to the following methods of starting the engine in cold weather:

In no case should you try to start the car “from the pusher”, resorting to this method, you will not only damage the gearbox, but you can also ruin the engine.
If you are trying to use a third-party source of electricity to start the starter, do not confuse the plus and minus, otherwise the matter will not end up with blown fuses.
Do not change transmission modes with the engine turned off, this can also lead to transmission failure.

Now you know how to start a car in cold weather. We wish you success in your work!

There are also specific features of how to start a car in winter, depending on its configuration:

injector,
carburetor,
automatic transmission,
diesel engine etc.

But, since the most popular cars- these are cars with automatic transmission and an injector, then a separate conversation will be held about them. But remember that excessive fanaticism in this matter can even lead to the fact that you need a car engine repair. So, if the car categorically does not start, it is better to contact specialists.

How to start an automatic car in cold weather

Let's start with how to start an automatic car in cold weather. The main difference from the manual transmission here is that the car cannot be started “from the cable”, since the automatic transmission does not leave such an opportunity. In addition, towing such a car is complicated. IN sub-zero temperatures transmission oil in the automatic transmission it thickens and it is highly undesirable to tow a “frozen” car into a box or service. Hence the first recommendation: do not overdo it. The main cold start problem is insufficient battery charge. If you feel that there is not enough charge and the starter turns sluggishly, then do not torment it. Use a simple and proven method: "lighting up" from the battery of another car using a special set of wires.

Lighting up a car is easy: connect the red wire to the positive terminals of the car, and the black wire to the negative terminals, then wait a couple of minutes and try to start

Many do not know how to start a car with an automatic transmission in cold weather and begin to use the same tricks as in a car with a manual transmission, for example, depress the clutch pedal. This is not at all necessary. If the selector is in the “P” or “N” positions, the automatic transmission does not participate in the launch in any way. By the way, if after several attempts, even with a working battery, the starter turns fine, but the car “does not catch”, then the candles are most likely flooded. They must be removed and calcined or changed.
