How to start a diesel engine in cold weather: advice from experienced drivers. Diesel does not start "cold": reasons

30.04.2019

Diesel power plants are distinguished by reliability and performance. They are hardy, but demanding on fuel quality, and temperature regime their operation. Diesel problems often occur in winter when the air temperature drops to -20 -30 degrees.

If the car is difficult to start, you should take the advice of experienced motorists.

When the question arises how to start diesel engine In cold weather, the first thing to do is to check the health of the battery. He must actively turn the starter, otherwise the car will not start. You can try to recharge the drive, but if that doesn't help, you'll need to replace it.

There are several options for starting a diesel power plant in winter, the main thing is to use the products correctly and not to use them too often.

Proven Methods:

The use of ether effective way start the motor. To use such a substance, you need to open the case air filter and spray it. So, the composition will fall into intake manifold, warming up the air directed to the cylinders. Regular use of ether is dangerous for the motor housing.
Antifreeze compounds - can be used, but are characterized by high cost and are not effective enough with a serious drop in temperature.
Boiling water, hot water - is necessary to heat the tank, while diesel fuel is also heated, which ensures normal work unit.

In order not to constantly worry about how to start a diesel engine in cold weather, you can install an autonomous pre-start device. An equally attractive option is an alarm with auto start, which provides periodic heating of the system depending on the set temperature and conditions. environment.

With the onset of the cold season, a diesel engine must be refueled with winter fuel.

This is one of the main conditions for a trouble-free start in cold weather. The peculiarity of such diesel fuel is that it is able to maintain characteristics at more than low temperatures. Here it is worth paying attention at what temperature it freezes diesel fuel.

According to the established standards, turbidity, gelling is possible:

after -25 -35 degrees (if high-quality winter diesel fuel is used);
after -45 -65 for arctic fuel.

When the ambient temperature drops below 0, the fuel that is used in summer period cannot be used. It is rapidly losing desired properties, becomes gel-like, paraffin is released.

But even when choosing high-quality fuel, the possibility of freezing with a strong drop in temperature cannot be ruled out. To avoid unpleasant situations, it is worth using an antigel. This is a special additive that can affect the low-temperature performance of diesel fuel. So, even in hard frost, the fuel will be pumped and sprayed.

When choosing a gel for diesel fuel in winter, you should give preference to products of proven brands, otherwise it is easy to purchase compounds that will harm the car. One of the best additives is Hi-Gear Super Anti-Gel.

How to use the additive:

the composition can be added directly to the tank before refueling, and when fuel is supplied, everything will mix well;
another option involves adding a mixture of additive and fuel to the tank.

Keep the antigel warm, otherwise it will freeze.

If the temperature drops below -10 degrees, you should not rush to start, first it is recommended to ignite the candles, if they are provided on the machine.

For this you need:

turn on the ignition, with which the glow plug relay starts to work;
after 10 seconds, the ignition must be turned off, and after 5 seconds, repeat the procedure again, paying attention to the operation of the glow plugs;
when the light goes out, you can start the car by working the gas pedal if the car does not have an electronic injection pump.

If this did not help start a diesel engine in winter, tips seasoned motorists indicate the need to check some systems.

What to look for:

If spark plugs are installed, they are checked first of all - they remove the tire, unscrew the candles. Using a thick wire, connect + to + drive, case to minus. When the candle is working, it takes no more than 5 seconds to glow the tip. If glowing takes longer or does not occur, a replacement is needed. This method works for 12 volt plugs, if they are 6 a pair test is performed.
Relay - may not supply current to the bus. The check is carried out on a cold car using a light bulb or a tester. Here, one contact is connected to the bus, and the other to ground, and the ignition is turned on.

If the car is equipped with a diesel engine, starting in winter can be a real problem. So that the operation of the car does not cause trouble, preparing the car for cold weather, you should make sure that the battery, candles are in good condition, refuel with high-quality fuel, use an additive.

Looking through the forum, it's easy to come across various situations, in which car owners tried to start a diesel engine in cold weather, tips and an optimal algorithm of actions will help to avoid many problems.

Option number 1

Several times in an attempt to start the car, the starter actively turns, but the engine does not start, while the candles are fully operational. Usually the reason is the lack of fuel supply - paraffin clogged the receiver grid or is present in the line.

What to do:

using a pump, compressor, you need to blow through the line;
warm up the tank, directing heat from the burner along the structure;
if necessary, the equipment also warms up, here it is enough to use hot water.

Option number 2

The engine starts, the car drives for a while. But soon there is a loss of traction, dynamics, when gassed, the power unit is etched, the car stalls, does not start again. This means that the intake screen in the tank is clogged. To fix the problem, it is enough to warm up the tank.

Option number 3

After blowing through the line, warming up the system, the tank, the engine starts, but it cannot develop speed, the car does not drive. So the paraffin clogged the filter fine cleaning- it needs to be warmed up. You can also pour warm diesel fuel, heating it separately.

Many owners of diesel cars are apprehensively waiting for winter frosts, since almost every one of them had to deal with the fact that the car does not start in sub-zero temperatures. The main reason for this is the thickening of diesel fuel at low temperatures. This trouble happens due to the formation of small paraffin particles in diesel fuel. However, if you apply small tricks that experienced drivers use, you can figure out how to start a diesel engine in cold weather.

In order for a diesel engine to easily start in severe frost, it is necessary to take into account such important factors:

good and proven fuel;
reliable battery;
working starter;
quality candles.

A prerequisite is also normal compression and serviceable injection system. When at least one of these points is inoperative or works poorly, the diesel engine will not start in frost. By the arrival of cold weather, it is necessary to check the operation of the engine in a good workshop. A smoking engine indicates a lack of power, uneven operation, or problems with compression. This is one of the main indicators that can characterize the entire operation of the motor.

Checking the diesel engine is carried out using a pressure gauge, which is connected directly to the injector. Thus, it is checked operating pressure in the cylinder during operation crankshaft. If the car is new, then this indicator should be at least 30-40 bar. If the pressure in the working cylinder is lower than 20 bar, then starting the diesel engine in frost will definitely not take place. But this is more common on vehicles with high mileage, where the engine is already developed. In such a case, it is necessary overhaul motor or, as an option for winter, a warm, heated garage. In the warm season, even strongly worn engine starts without problems.

Possible problems with the injector

In older cars with high mileage, the problem with the injector usually manifests itself when starting the car, there is also significantly reduced power and smoke exhaust pipe. Such an engine starts to work too noisily, it seems to be knocking with something metal. If the car is new, then you can find out that the injector is not working by hard braking after pressing the gas pedal. The cost of injector repair varies depending on the year of manufacture of the car, the newer the car, the more expensive the injector repair will be.

Battery Disadvantages

As practice shows, start any diesel auto mobile is much more problematic than starting a car with gasoline engine the same power. Therefore, diesel engines are equipped with batteries and starters that are much more powerful. IN winter time all defects in batteries manifest themselves in a double size, since in severe frosts the need for an engine in electricity increases significantly. Frost thickens the fuel, the starters spin harder, and the spark plugs need to run longer. Usually, the colder it is outside, the less battery power. How to start a diesel engine in cold weather becomes the main issue even for experienced car owners.

To avoid many problems in advance, you need to take a closer look at the work of the starter. If it does not work well or after a couple of attempts to start it noticeably weakens, then you need to contact a specialist. The service station will check the performance of the battery and all parts of the car used to charge it. If you buy immediately new battery, without checking the old one, it is often just a waste of money, perhaps the problem is not in it. The alternator or starter may be faulty. Life time modern batteries is three to five years.

Fuel and fuel filter problems

With a sharp drop in temperature in the tanks of most diesel vehicles summer diesel fuel is also poured, which tends to thicken strongly at a temperature of zero degrees. Paraffin, deposited in frost from such fuel, can completely clog the fuel filter, this is one of the reasons for the inability to start a diesel engine correctly in frost. If, for some reason, summer fuel was not used, a special additive, an antidepressant, must be poured into the tank. This will help to reduce the thickening parameters of diesel fuel. Experts recommend changing the fuel filter before the onset of frost, in diesel engines the filter design provides for a sump to collect water, if there is a lot of liquid in the sump, then in frost it will freeze and limit the flow of diesel fuel into the engine.

Most diesel owners think that the troubles with the diesel engine factory in winter period are obtained due to diesel fuel, which does not correspond to the season. There are only three types of diesel fuel:

summer diesel fuel - used from zero degrees and more;
winter diesel fuel - poured at negative temperatures up to minus thirty degrees;
arctic fuel - used in diesel vehicles at temperatures below minus thirty degrees.

The most important difference between all these brands is the temperature of the thickening of the fuel. If the fuel is filled according to the season, then the use of special additives is not required. If all systems of the car are in good condition, the diesel engine will start in the cold on the first try.

Candle failure

It is very rare that all car candles fail at the same time. If the car is old and with high mileage, the driver may not even notice the failure of a separate candle, it’s just that when the engine is started, the engine starts weaker and its work is uneven for several seconds. In the fall, it is advisable to conduct an audit car candles and replace defective items.

The performance of candles can be checked without contacting specialists. The element must be pulled out, the contact from the minus connected to the body, and plus thrown onto the candle terminals. When the candle is working, the tube will instantly warm up. After a few seconds, it will fully heat up and it will glow.

Proven ways to start a diesel

A very reliable and proven way to ensure correct functioning fuel design diesel car, is the installation of a heating structure in the fuel tank, on the pipes and on the filter. It is very easy, although dangerous, to start a diesel engine using a tug.

Passenger cars are equipped with a belt-type distribution system drive. When a tug is used, jerks are inevitable, this can lead to a break in the belt. You can use the tug only in hopeless situations when the battery is dead or the starter is broken.

Take some advice from experienced drivers:

if the diesel engine is started in frost, it is necessary to turn it on for a few minutes distant headlights, then depress the clutch for a few seconds, and then let the starter rest, this can help the diesel plant;
you can add kerosene to the fuel, even if long-term operation in sub-zero temperatures, such a composition does not affect the operation of the entire diesel engine structure;
use additives that reduce the thickening point of diesel fuel;
to quickly warm up a frozen diesel engine, you can put a cover on the car and put a heat gun under the bottom. The temperature under the engine must be brought to at least zero degrees;
if we start a diesel engine in frost, then for a quick start, you can sprinkle ether into the air intake, you need to try to start the engine while the ether is in a sprayed state;
another method proven over the years from experienced drivers of diesel cars. If the car does not want to start in the cold, it is necessary to warm up the drain manifold. This can be done elementarily, with a piece of paper and matches. The paper is set on fire and the collector is heated with the help of smoke, in this case the machine starts up very quickly;
you need to buy diesel fuel only at proven gas stations, saving on diesel fuel, you can spend a lot on repairs.

Conclusion

Diesel vehicles are popular due to their power and efficiency in operation. But for all these advantages, lovers of such cars suffer in winter frosts. The transition period from autumn to winter is especially troublesome, it is at this time that there are frequent frosts, and the fuel in the car is mostly filled with summer fuel. So you have to spend hours trying to start your car. If you follow the advice of experts and carefully monitor the car, then even in severe frosts such problems will not arise.

The winter start-up of a diesel internal combustion engine is an actively discussed topic among owners of cars that are operated on diesel fuel during the cold season. With the onset of intense frosts, it becomes a frequent occurrence that cold start diesel engine is difficult or completely impossible, a serviceable diesel engine is unstable or stalls right on the go. Let's look for answers to the questions what to do if diesel engine does not start in winter, and also how to start a diesel engine if diesel fuel is frozen in the tank.

Most often, a fully serviceable diesel engine cannot be started in the cold precisely because the diesel fuel in the diesel engine has frozen. Unprepared diesel fuel thickens, becomes cloudy and paraffinized in fuel tank, filters and lines of diesel engines already at relatively low negative temperatures.

How to start a diesel in cold weather

Comprehensive measures for starting a diesel internal combustion engine with a strong and not very negative include pre-filling the tank with warm fuel, to which an anti-gel additive has been added. Separately, consider the proportions and recommendations regarding the addition of antigel to diesel fuel. Also remember that modern diesel engine manufacturers do not recommend, and sometimes completely prohibit, the use of fuel additives.

For simple diesel cars of the 90s, gasoline or kerosene can be added to diesel fuel, but if this is done with new turbodiesels, then the result is unpredictable, especially with gasoline. Sensitive fuel equipment is already afraid of additives, and with kerosene or gasoline in diesel fuel, it can completely fail. It should also be taken into account that an attempt to simply pour the additive into a tank with previously frozen diesel fuel will not bring results.

If the diesel fuel in the tank is frozen:

be sure to direct a building / household hair dryer to the fuel filter;
similarly direct a hair dryer to the gas tank for more efficient heating;
first, gently heat a canister of diesel fuel to 60 - 70 degrees;
then add the additive and pour the finished mixture into the fuel tank;

Replacing the fuel filter with a new one will speed up the process, and warm diesel fuel with anti-gel should help start the diesel. If there is no hair dryer and the replacement of the fuel filter is not planned, then you need to wrap the filter installation site with a rag and pour hot water there. Similarly, you can water hot water and fuel tank.

Kerosene in fuel for older diesel engines is also suitable. Its lubricity is much higher than that of gasoline. Harm to fuel equipment of the old diesel engine is minimized (experts allow, in extreme cases, the addition of up to 25% of kerosene to diesel fuel), which cannot be said about new diesel units.

As for the gasoline in the tank of a diesel car, it does not lubricate the parts of the fuel equipment, so gasoline in diesel fuel is suitable for extreme cases. When diluting diesel fuel with gasoline, it will not be superfluous to further dilute this mixture with engine oil, which will perform the function of lubricating parts fuel pump diesel. Once again, for new diesel engines, all these measures are extreme.

After the performed procedures and cold start in severe frosts, let the diesel engine idle for about 15 minutes to warm up. It is necessary to wait until the warm fuel from the engine begins to enter the tank through the return line (the return line warms up). Only after that you can go, eliminating the risk that your diesel engine will start to stall on the move after a few tens of meters.

Battery status

Modern cars are oversaturated with electronics, so the battery runs out quickly, especially in winter. A diesel engine requires a powerful current source to warm up the glow plugs and start confidently. Monitor battery health, proactively service, charge and replace battery immediately if needed.

Glow plugs

An equally common reason for a diesel engine to fail to start in the cold is glow plugs. If diesel internal combustion engine in order, then even at -5 the engine must start with one or two faulty candles incandescent. At lower temperatures, starting a diesel engine with such candles will be impossible.

The failure of diesel glow plugs can be diagnosed by the delay at the moment of setting the internal combustion engine. A cold diesel engine "troits" a little at the time of start-up and requires support from the starter. Inexpensive glow plugs are different poor quality and can fail literally in a season, so it’s better not to save on them.

To start a diesel engine at low temperatures, use simple method. It is enough to turn on the ignition several times before starting. This method helps to warm up the glow plugs. Then you can start turning the starter. For older diesels, simultaneously pressing the gas pedal to the floor is also suitable.

Results

It is quite obvious that when the diesel is frozen, it is better to warm up the car and try to start it in a warm box. But if you are sure that the problem is only in the battery, then you can try to start with another car.

Attempts to “light up” a diesel car include certain risks in the form of a failure of electronic components, both in the car that is being started and in the car that is the source of current. If there is an urgent need for such manipulations, then it is correct to use power cables with a large cross section.

When it is decided to start a diesel engine with the help of a tug, then try to start the engine no lower than from third gear, and also release the clutch in the presence of a manual transmission as delicately as possible. We add that it is better to refrain from such methods of starting a modern diesel engine by “lighting up” or towing at the slightest opportunity to separately recharge the battery or deliver diesel car into a warm box without starting the internal combustion engine.

Diesel does not start in winter: a solution to the problem

In order to easily start a diesel engine in cold weather, you should always take into account some factors:

reliable engine;
starter in working condition;
quality fuel.

Moreover, the main condition is often called normal compression. Therefore, if any of specified points does not work as it should, and therefore, the diesel engine will not start in the cold. Therefore, before the arrival of the cold, it is advisable to double-check the entire engine in the auto repair shop. If it smokes, then it does not have enough power or works unevenly. This is one of the indicators characterizing the entire operation of the motor.

You can check the diesel engine using a pressure gauge that is connected to the injector. As a result, the working pressure in the cylinder is checked. If the car is new, then a similar indicator must be at least 30 - 40 bar. When, during measurements, it is found that the working cylinder of a diesel engine has a pressure of less than 20 bar, then we can safely state the fact that the car will have problems starting in winter. As a rule, all this is found on machines that have high mileage, where the motor has already been developed. Therefore, an overhaul of the engine or a warm garage is required, for winter time. Since even the most worn-out engine starts up without any problems in warm weather.

How to start a diesel engine in cold weather: help for motorists

What to do to start a diesel engine in cold weather? The advice of more experienced motorists will always come to the rescue, thanks to which you can easily overcome a large number of problems:

Attempts to bring the diesel engine to normal operation should begin with warming up the power source (battery). It is worth noting that it is strongly not recommended to keep headlights and other light sources on at this moment. It should also be mentioned that for gasoline engines it will be useful to warm up the spark plugs. In a diesel engine, this will not need to be done due to their absence, because the controlled ignition of the fuel in the engine occurs not due to the supply of a spark, but due to compression. At the initial stage, for a diesel engine, it will be enough to turn and hold the key in the ignition for a few seconds, repeating the procedure cyclically at intervals of half a minute.
Sometimes diesel vehicles are equipped with a start-stop button. The peculiarity of such a button is that it is associated with the system preheat fuel in the fuel system. To carry out preheating, it is necessary to press and hold the button for a few seconds until the corresponding sign appears on dashboard about the engine ready to start.
Start the diesel engine only when the clutch is engaged. Moreover, the starter rotation time is approximately 15 seconds and this is enough to start the motor. And if it didn’t work out right away, then you need to turn off the ignition, wait a couple of minutes and try again.

Is it possible to start a diesel engine in cold weather from a pusher?

If the car is frozen and it cannot be started, then it is worth trying to start it from the pusher. However this way not desirable to use. The reason is the timing belt, which can easily break or jump forward a few teeth due to sharp jerks. Consequently, any attempt to start a diesel engine in cold weather from a pusher often turns into an expensive repair.

We start a diesel engine in frost from a tugboat

If the diesel engine cannot be started in any way, and other methods do not help in any way, then you can try one more attempt - to start the diesel engine in the cold from a tugboat. Of course, this is a very dangerous method, which is desirable to use only in the most extreme cases. Because machines with a belt drive are at risk and can easily break down. However, he also has his positive sides: great opportunity success, no sudden jerks and a relatively smooth acceleration than by pushing a car.

To start a diesel engine in cold weather, the advice of professionals will help less experienced drivers just right:

if the diesel does not want to start in frost, you should turn on running lights or lights high beam for 1-2 minutes, after pressing the clutch for a few seconds and then leave the starter at rest;
you can add a little kerosene to the fuel, because even during long service life at sub-zero temperature, a similar composition never interferes with the operation of the entire diesel engine;
additives can be used to reduce the extreme temperature threshold at which diesel fuel begins to freeze. When a motorist tries unsuccessfully to start a diesel engine at low temperatures, then for quick launch it is necessary to sprinkle with ether into the air collector and try to start the engine while the ether is still in a sprayed state;
in order to warm a frozen diesel engine, it is advisable to put a cover on the car, and put a heat gun under the bottom. Moreover, the temperature under the engine must be at least 0 degrees;
you can warm up the exhaust manifold. All this is easy to do with a piece of paper and matches. The paper needs to be set on fire and the collector heated up with smoke. As a rule, after that the car starts up just instantly;
check the condition of the fuel. If the diesel fuel has thickened, then it is necessary to call a tugboat and put the car in a warm place so that fuel system could warm up
always buy diesel fuel at good, proven gas stations. Having saved on diesel fuel, in the future you can easily spend money on expensive repairs.

Diesel cars are very famous for their own power, as well as efficiency during operation. However, for all these positive aspects, motorists suffer greatly in the cold season. Especially when there is a transition from autumn to winter, because it is in given time there are frequent, severe frosts, and the fuel in such cars is mainly filled with summer. As a result, you have to try to start for hours own car. But if you listen to the advice of experts, and most importantly - always carefully monitor your true friend, then even the most severe frosts will never bring problems and worries.

Also, do not forget that frost and cold bring a lot of risks to both motorists and their cars. Therefore, in order to avoid a large number various difficulties with the operation of a diesel engine, it is required to start it as correctly as possible, and most importantly, fill in only the best, high-quality fuel. Thanks to this approach, you can easily solve the most important problem - extending the life of a diesel engine.

Have you ever started the engine in extreme cold? Share your experience in

In winter, many motorists are faced with the problem of difficult starting the engine. This is especially true for vehicles running on diesel fuel. The engines of such cars are arranged somewhat differently. Therefore, for them there are separate rules on how to start a diesel engine in cold weather. Let's look at what affects the launch and how to prepare your iron friend for winter operation.

Compression

This is one of the main factors that affects the quality of the launch. Diesel units are different from gasoline more compression and compression ratio. Let's look at how this factor affects the launch power unit:

Compression up to 18. This is a very low figure. The operation of a diesel engine in winter in this case is impossible. The car cannot be started even "hot".
From 20 to 24. In this situation, the car can be started, but only in a warm box. If he stood overnight on the street, it will be extremely difficult to start him.
About 25. Here the unit can operate at temperatures up to minus 10 degrees Celsius.
Compression 26-30. The start temperature indicator drops to minus 15 degrees.
32 and above. This is normal compression, which should be in a serviceable diesel car. Such a power unit will start without problems at a temperature of minus 20-30 degrees Celsius.

As you can see, the compression ratio significantly affects how the engine performs in the winter. The higher it is, the greater the chances of a successful launch.

How to check the value?

To do this, use a device - a compression tester. But the measurement procedure is slightly different from that performed on gasoline engines. The compression gauge is screwed into the injector installation site.

Next, the engine is started. In this case, you do not need to press the accelerator pedal. Three or four revolutions of the crankshaft are enough for the device to “grab” the maximum readings. If the compression is below 17, the engine may not start at all. Normal values should be around 30, but not less than 24 revolutions. It is worth checking the engine with a run of more than one hundred thousand kilometers, as well as in anticipation of winter season. Having eliminated the breakdown in advance, you will not be faced with how to start a diesel car in the cold. Repair required to increase compression cylinder-piston group. However, this procedure is already performed by specialists.

Battery

A fresh battery is a guarantee of a successful start at any time. And it doesn't matter if you start the engine "hot" or "cold". good charge will ensure good rotation of the crankshaft, and as a result, a quick start of the power unit. Life time battery is three to five years. it is worth noting that a diesel unit requires more energy to start than a gasoline unit (even if the compared engines have the same number and arrangement of cylinders). Before the start of winter, check the electrolyte level. If the liquid has boiled away in a small volume, it is recommended to replenish it with distilled water. It is strictly forbidden to pour the usual "from the tap". Also check the quality of the connections at the terminals. Sometimes they oxidize, as shown in the photo below:

In this case, it is recommended to clean them in order to ensure a quality connection of the conductors. To do this, remove the terminal and pick up coarse sandpaper. Also check the contacts that go to the starter. If necessary, they are also cleaned of dirt and deposits.

Filters

If your diesel does not start, the problem may be in the accumulated "sludge", which in fuel filter. Dirty particles interfere with the normal supply of fuel. The resource of the fine filter is 10 thousand kilometers. Regarding the element coarse cleaning, you can simply blow it out with a compressor and install it back. The main part of the dirt accumulates in the second filter. The fine cleaning element retains particles up to 10 microns in size. By itself, it is a porous paper placed in a metal case.

If the diesel does not start, then given element dirty and needs to be replaced. When preparing your car for winter, do not forget about the air filter. Since the engine requires not only fuel, but also oxygen, the state of this cleaning element directly affects the quality of work and engine start. The advice of experienced drivers says that this filter should be changed as often as possible (but no later than 10 thousand kilometers). Its resource is especially reduced when operating in rough terrain, where instead of asphalt there is slag and a primer.

Oil

In order not to ask the question "how to start a diesel engine in the cold", for the winter you should change engine oil. Manufacturers are now producing lubricants not only by the type of engines (diesel or gasoline), but also by seasonality. In the cold period, it is allowed to use a less viscous oil. This will greatly facilitate starting the engine in winter.

glow plugs

Gasoline engines use spark plugs to ignite the mixture. Diesel engines are built differently. It does not require an additional spark to start and operate - the mixture ignites from high degree compression. But modern manufacturers equip diesel engines with auxiliary elements. Among them is a glow plug. It heats up the diesel fuel for a more successful start.

This is especially true in winter. How to start a diesel engine in severe frost? To do this, you need to wait until the candle heats up the fuel. Turn the key to the third position. lights up on the instrument panel. control light. It is usually red or yellow color. After a few seconds, it will turn off. As soon as it stops burning, we start the engine. Thus, you stand more time so that the candle heats up the fuel better.

How to start a diesel engine in cold weather? Ether in an aerosol

Surely you have heard of such tools as "easy start". These products are available in small aerosol cans. They are useful in that they can start a diesel engine even in extreme conditions. The product contains flammable substances. Due to them, an “easy” start of the engine is made. The mixture begins to burn out earlier - the chances of a successful start increase several times. But it is worth remembering that in large quantities flammable substances harm the diesel engine. Therefore, such a product should be used only in emergency situations.

How to start a diesel engine in cold weather using the “easy start” tool? To do this, unscrew the air filter housing, or better, remove the pipe. Directly into it we begin to spray the composition. At this time, the assistant cranks the starter. The motor will start easily.

Is it possible to start "from the pusher"?

Surely many of us have seen how the Zhiguli and Volga are started in this way. Accelerating the car to minimum speed, the driver turns the key - under pressure, the mixture ignites. But the trouble is that this cannot be done on a diesel engine. That's why this option launch is excluded in the first place.

We dilute the fuel

Everyone knows that diesel, unlike gasoline, has two varieties - summer and winter. The so-called arctic fuel does not always appear at gas stations on time. There are severe cold spells. Then the question arises of how to start a diesel engine in winter on summer diesel fuel. Since its crystallization temperature is an order of magnitude higher, it freezes more easily. At minus 10 degrees, it turns into paraffin.

It is simply impossible to start the engine on such fuel. How to be in such a situation? To do this, we need to dilute the fuel in the tank with a special "winter" additive. The same is added to filling stations(into the same "summer fuel"), therefore, consider this product as foreign and harmful to diesel unit not worth it. It is recommended to pour the product in advance (for example, overnight). In the morning you successfully start the engine on summer fuel. The product is inexpensive - about 400 rubles for a 500-ml bottle. But there are times when diesel fuel crystallizes in the filters themselves.

And here no additive will help. How to start a diesel engine in cold weather? For this, third-party elements are used. Simply put, the filter is heated with a gas or kerosene burner. Do not worry - diesel fuel will not catch fire from such a fire. The main thing is not to fall into plastic elements that may melt. This is the most the right way who manage to start the engine in any cold.

Experienced drivers are advised to use kerosene as an additive. It is diluted in a ratio of "one to ten". Kerosene is not harmful to a diesel engine. And the effect is the same as that of specialized additives. The product will make diesel fuel more liquid, and excess substances will evaporate through the ventilation system crankcase gases. If there is neither a burner nor kerosene with additives at hand, you can heat the filter using improvised methods. For example, boiling water from a kettle, or a hairdryer. This is especially true for machines with plastic fuel lines. Under influence high temperatures, the diesel oil will become less thick, and you can successfully start the car.

Starting a car with automatic transmission

The automatic transmission has a torque converter in its design. It works thanks to the oil that is inside. In winter, it also thickens. On cars with manual transmission, to disconnect the box from the engine, just press the clutch pedal. On an automatic, the starter has to expend energy to turn the flywheel and gearbox shaft because the assembly does not fully disengage.

This makes starting the engine difficult. In order to successfully start the engine in winter, it is necessary to change the oil in the automatic transmission more often. The cleaner it is, the easier it will be for the motor in winter. In extreme cases, warm up with a hairdryer, but this applies to cases where the temperature is far beyond minus 30.
