Engine break-in rules after buying a new car. Breaking in is a mandatory procedure for a new car.

11.04.2019

Gone are the days when the car was omnivorous and unpretentious. Any fuel, tolerances, oil — everything was fine. "Wheelbarrows" smoked, rumbled, but they performed their main function. The owners of modern vehicles do not even know what it is. Their cars are fast, reliable and comfortable.

However, it will be possible to obtain such characteristics only under one condition - you must strictly follow the instructions for using the car. Anyone who has ever bought a car knows how nice it is to drive straight from a car dealership to new car the envy of all! Breaking in a new car is the first step in a car's life and one of the most important.

How to break in a new car

So you bought new car. For example, it could be Kia, Chevrolet or Volkswagen. And maybe even domestic production- Priora, Kalina or Granda. In fact, the brand of the car is unimportant. Breaking in a new car is not difficult, but it is important to follow a few break-in rules.

The rules for running a new car are really simple! But if you are not sure of your actions, attract experienced driver to break in a new car, this will reduce the risk of failure. It is important to strictly observe the maintenance period, use a certain brand of fuel, oils and various fluids that the manufacturer advises.

Practice shows that not all motorists follow the instructions. Some car owners intentionally violate them, while others simply do not know how to break in a new car and whether a new car needs to be broken in at all. As a result, the car suffers. If you want everything to be in order with the car, imagine that the manufacturer's instructions are the law! Similar condition will be especially important if the car has not yet learned to drive. It is necessary to break in a new car until the first thousand kilometers have appeared on the counter.

There are many different opinions on how to properly break in. Don't be scared, it's not that hard. Remember, any new car needs mileage, otherwise there is an opinion that a modern car does not need it. Parts of a new car are brand new, they must be rubbed in for correct operation. Lack of break-in will reduce the life of the machine, repairs will be required very quickly.

Especially important correct break-in a new car to automatic transmission or in winter, when weather and temperature conditions can affect the condition of the car. In fact, running a car in winter is no different from running in summer. The main thing is to treat the car even more carefully. Here are a few useful rules, which will help to break in a new car:

For the first couple of thousand km, do not press hard on the gas, do not scoff at the new car. Be careful - this is the way to properly break in a car. Do it according to the instructions.
When you start the engine, do not allow it to rotate at high speed crankshaft. Try to keep the RPM range at crankshaft was not the same.
Don't let your new car run for a long time idling engine.
Also, it is not recommended to depress the accelerator pedal to the very end.
During break-in, the crankshaft should not be under heavy load if low gears are used.
In addition, avoid driving at the same speed for a long time (no matter how high or low it is). When running in, it is recommended not to move at the same speed, this will help save fuel and the reliability of your car. This, of course, does not mean that one should car traffic and your neighbors down the road at risk.
It is very important to use the low gear of the manual transmission in time, given the conditions of the road. Thus, you will protect the motor from overloads.
Do not brake hard on the car after driving the first hundred kilometers, as this will damage the brake pads. Otherwise, you will not see the coordinated work of the brake linings.

When buying a car, you may be told in the cabin that the manufacturer performed a “cold” run-in, and therefore you can refuse to run in a “hot” one. You should be aware that manufacturers have different goals. They seek to identify shortcomings during engine break-in.

When running in a new car, you can even free the car from excess luggage. Avoid trailers at the very beginning of operation. Choose a road of acceptable quality so that there is no sand, dirt.

During and after vehicle break-in

Running in a new car with automatic transmission involves monitoring the condition of the gearbox. First of all, an automatic transmission requires more careful handling than a mechanical one (this is a question). This is especially true for running in a new car in winter, when subzero temperature affects the condition of the oil in the automatic transmission. Before moving into winter time, a car with automatic transmission must be thoroughly warmed up, up to operating temperature engine.

The oil level as well as other fluids needs to be regular check. Also check the bottom of the car, nothing should leak. This will make it possible to identify defects even at their initial stage. Remember that proper break-in prolongs the life of the transmission and engine, makes their operation reliable and economical.

If the engine runs out of oil and you are still running it, then this can lead to the need to replace the engine, which is an expensive and dubious “pleasure”. The oil level should be checked when your car is on level ground. When checking the level, you need to wait five minutes after the engine has stalled, and then check what the oil level is. If it is almost at the minimum, then it must be topped up. Carefully consider the choice of oil, it should be good quality and of the same sort.

After 1000 km, it would be necessary to call in a car service, pass an inspection. There you can find out the condition of your car, clarify everything you see fit. This will make it possible to correctly complete the break-in of the car. In fact, the rules are simple. If you follow them, then the vehicle will not let you down! We hope our tips on how to properly break in a new car have helped. Come on!

Let's talk about what a car break-in is and how to properly break in a new car engine, which is worth remembering.

Running in a car is a concept that has been forgotten since the days of the USSR. Then in technical books the rules for correct running-in and the number of revolutions required were indicated. But that's all in the past. Now on the street is the 21st century, which means that automotive industry does not "stand still".

Briefly about the concept of running in

Running in a car is the first movement of a car, on which the future operation as a whole depends. Since progress has taken its toll, today, after assembling the entire passenger car, its parts under the hood lend themselves to both hot and cold running. Most motorists believe that hot and cold running in production, even more than just enough. Although, it is safe to say that the main part of the car in this process is not only the engine.

Roll or not?

In general, it is necessary to break in a car after buying it at a car dealership or after a major overhaul, since no one knows how to properly break in a car at the factory. All its smallest elements must work flawlessly and as a whole. Therefore, if it is possible to run in the newly-made “iron horse”, then it is advisable to do this. Try to follow the basic rules of running.

A little about the engine and running gear when running

The first rule of good engine performance is well-lapped parts. Special attention is required piston rings and engine valve. And in general, all other elements should not remain in the background when viewed. At first, when running in, there will be a feeling that the engine is a little dull, and the declared power is not at all the same. But over time, after grinding all the details, the power will increase, and it becomes frisky and quickly responds to the gas pedal. So nothing needs to be broken in like a car engine.

Also, do not forget about brake mechanism during the run-in. The pads should fit under the discs. If you stick to this, then you can achieve efficiency and longevity in working from pads and discs.

The transmission in running-in and inspection takes no last place. Even, regardless of which gearbox is installed in the car, manual or automatic. The first run-in of the car is a kind of familiarization. During break-in and further driving, you need to “feel” it. This is done in order to prevent, or in extreme cases, to notice problems from which no one is immune.

Now about the driving style during break-in

The first thing the driver should remember is that you can not sharply press the gas pedal, or press the brake pedal. These actions will load the engine even more. And even more so, you don’t need to ride tight when running in. Before the first trips, you should warm up the engine as best as possible, especially if it is cold and frosty weather. All of the above should be done on smooth roads (best if it is a highway), and not at rush hour and on crooked roads.

If a supported car was on hand, and when the mileage shows three to five thousand kilometers on the counter, then this is the first sign that you need to change the filters, engine oil and complete technical inspection. But, if during the inspection no deviations and breakdowns were revealed, then we can safely say that the car has been run in.

As for used cars, it’s worth looking closely and listening to the engine and chassis during the break-in, if you took it from hands you don’t know. Such a car is much better in terms of its operating and technical specifications than new. Engine uses less fuel and oil during operation than a completely new one, it responds faster to the gas pedal, but it’s still better to look at the oil level more often and look closely at the operation of the piston and valves, so it’s not worth running in a new engine in its own way.

The perfect break-in process for a new car

The most important in the running-in of the car are the first 200 kilometers of engine operation. For a break-in, you should choose a calm and not overloaded with cars place, in case the motorist lives in a noisy metropolis.

When the car has moved, it is then that it is necessary to monitor the engine speed. During the first break-in, the number of revolutions should not exceed 2500 rpm. The process of running the first test has five stages.

The first stage: for the first 50 km, the driver must drive a car at a speed of 40-50 km / h, such a run-in is the most important, since the quality of the engine in the future will depend on it.

The second stage: the next 100 km speed is allowed on the speedometer somewhere around 60/70 km/h.

The third stage: the next 100 kilometers you need to drive at a speed of about 70-80 km / h, without overloading the engine with high speeds.

The fourth stage: and again you need to drive 100 kilometers, but already at a speed of 90 km / h.

Fifth stage: acceleration over 90 km / h is allowed, it is advisable to look at the temperature of the car engine and stop after a short distance and let the engine cool down.

First test passed. After the first break-in of the car, do not postpone the second break-in for for a long time. To do this, with a well-heated engine, dial 2500 rpm, and also occasionally increase the engine speed to 3000. If you drive on a flat road, or from a mountain (but not uphill), you can accelerate the car no more than 100 km / an hour and letting it go to neutral, let it drive without load, so you can hear whether the engine is running evenly and if there is any knocking in the chassis of the car. The next 500 kilometers during the break-in, acceleration of more than 100 km / h is allowed, but still, you should not abuse the position and push the maximum on the speedometer.

As a result, for a perfect break-in of a new car, you will need to drive 1500-5000 kilometers. And, of course, pay a considerable amount for fuel, but it's really worth it.

Other elements requiring break-in

In addition to the engine, there are some more parts that require wiping with a good break-in:

Chassis. It, in turn, consists of racks, hubs, wheels, springs, bearings in the hubs, anti-roll bars, suspension arms and ball bearings. These elements require running-in, after a while they need to be inspected before or after running-in. They can only wear out over time in a period long-term operation.
Steering. This control consists of a steering wheel, a steering column mechanism, steering rods, a steering rack along with a power steering, steering tips and swivel levers. These parts do not require inspection during break-in. You just need to inspect them after a long time of work. When worn, they should be replaced.
Transmission. The gearbox includes the following elements: connecting link, clutch (there is both hydro and cable). The clutch disc is lapped on both sides of the drive and driven discs when the car is running in. And as for the hinge of equals angular velocities, then it can only wear out during long-term operation.
Anti-lock braking system. It consists of: working cylinders, brake drums, brake discs and handbrake drive. From this list, you do not need to run anything, except brake discs that need to be slightly rubbed against each other. Everything else from this list only wears out during a sufficiently long operation of the car.

In the process of running the "iron friend" there is nothing complicated. The main thing is to remember the basic rules of running in and, of course, stick to them.

Running in a new car: how many kilometers do manufacturers recommend driving so that all components and parts get used to it, all systems begin to work smoothly. At modern cars a more advanced mechanism and some sales managers say that the motor went through a cold run-in at the factory and this was only required earlier, in the days of the USSR mandatory run-in car. But don't believe it marketing move and deny the experience of our fathers and grandfathers - it happens that it can be useful in modern conditions. The smoothness of its further operation will largely depend on how correct the running-in of a new car was.

So, we still convinced you that the running-in of cars is needed in without fail. A gentle driving mode will allow you to painlessly get used to the main components, identify existing defects, until they cause an accident or serious repairs, when something can jam in the car. During the break-in, the process of grinding gears, oil seals, transmission systems, brakes, gearboxes, suspension, chassis takes place.

The benefits of running a car

In order to bring the machine to a functional state, it is important to subject it to testing. For this, it is recommended to run in. During this process, the following results can be achieved:

smooth out all existing flaws and roughness individual parts and nodes;
achieve lapping of the moving elements of most nodes;
clean the engine and lubrication system from various chips and dirt after factory assembly;
get lapped brake pads;
identify defects and manufacturing defects.

But breaking the rules for running a new car can lead to undesirable consequences. But you can definitely get a guarantee that the steel horse will serve for a long time and faithfully. For everything to go well, it is important to follow the break-in rules:

check the engine oil level (a mark on half of the dipstick is enough);
check the presence of the brake mixture and coolant;
fill the car with high-quality fuel;
check tire pressure;
check for various lubricant smudges.

How many kilometers should the run-in last?

When a new car is being tested, you should not time it - pay attention to its length. Many motorists are just wondering “When running in new car, how many kilometers do you need to wind? On average, it should be at least 3 thousand km. But for each brand of car, the mileage will be individual - from 1 to 5 thousand kilometers. In many ways, everything will depend on the type of engine - for diesel engine the recommended mileage should be multiplied by two.

Driving a new car with manual transmission

it must be accelerated smoothly;
switch to low gears in a timely manner to avoid unnecessary loads;
do not allow idling;
do not exceed the speed of rotation of the shaft when starting the engine;
move at speeds up to 90 km / h for the first thousand kilometers;
do not include 4-6 gears;
you can not drive for a long time at one speed;
for gasoline engines to move at speeds up to 3 thousand revolutions per minute. For diesel - up to 1.2-5 thousand revolutions per minute;
switch gears in a timely manner.

Masters advise not to practice an aggressive driving style for the break-in period, hard braking and even more so driving uphill and towing. To prevent brake pad wear, you need to brake smoothly.

In any case, the driving technique must comply with pavement- on the primer it can be one, on the tracks - the other. It's better if the break-in is new cars will pass on routes with a small flow of cars and an excellent canvas. On difficult areas on the road, it is worth reducing the gear speed to prevent overloading the engine.

In the engine of a run-in car, after testing, it is worth changing the engine oil - all kinds of metal particles can collect there (you should not drain the manufacturer's oil before running in).

Running in a new car with automatic transmission

it is recommended to warm up the gearbox well before starting in order to achieve the desired consistency transmission oil;
monitor the oil pressure to prevent it from heating up and pressure on planetary gear;
you can not slip the wheels;
for running in, you should not choose city streets where the traffic is unstable - there may be braking and drops, which always has a bad effect on the operation of the “machine”;
heavy luggage cannot be carried during this period.

And in this case, after running in, it is worth changing the oil. Particular attention should be paid to the transmission. After the run-in has been completed, it is worth visiting the service station to undergo an inspection and identify possible flaws. It happens that quite a lot of them are found and it is important to remove them in a timely manner. The engine break-in of a new vehicle should not be heavy loads. It is impossible to carry out engine braking - such a test may adversely affect the operation of the main units of the machine.

For the first, the best option is 90 km / h and not 3.3 -3.5 thousand revolutions per minute. For a diesel engine, the first one and a half thousand kilometers should be driven at a speed of at least 2500 (no higher than 1200). Not the best option- idling. When the car is warming up, it is important to keep the level at 1200 rpm.

In addition to the fact that during the break-in process the engine is running, parts of the transmission are also rubbed, mechanisms brake system, including pads (sometimes this process is accompanied by a certain noise). By correctly shifting the gearbox speeds, you can achieve lapping friction linings transmission systems. After all, it is not in vain that they say that every car loves affection, care and lubrication. Happy all the way on a technically sound car!

Running in a new car with automatic transmission.

Just as any brand new thing bought “gets used” to its owner, so a car just released from the factory must get used to the owner, and the driver to the car. And to grind, in the literal sense of the word, will be many parts of the machine. Design and impeccable foreign cars, and domestic cars organized on the same principle. The whole car consists of a large number of so-called rubbing pairs - mutually rubbing parts. Therefore, any auto mechanic will tell you how important it is to first break in a new car under gentle conditions, save the engine, and only then proceed directly to operation. Perhaps some drivers do not even know that the wheels of a brand new car must first be run in for about 500 kilometers in order to “get used” to the disks, and what can we say about the rest of the details! Especially in order for the friction force not to have such a detrimental effect on the mechanism, all kinds of oils were invented that envelop the parts with a special film and protect them from premature abrasion. But no matter what magical power they possess machine oils, some of them are not enough to protect the car. For a new machine, one of the important conditions for its further proper operation is its competent running-in. And let the managers and dealers of car dealerships unanimously assure that running-in is not required and the manufacturing plant has provided for this, it is still better to save your “iron horse” and drive 2000-3000 kilometers under certain conditions than to pay for your indiscretion with endless repairs later. Experts advise you to follow a number of simple recommendations for running in a new car with automatic transmission, and then any trip will be pleasant and joyful. Try to avoid running the engine at constantly high or low revs. Also, do not let the engine idle. Undesirable braking of a car with automatic transmission, located on manual mode. When driving around the city, frequent sudden stops and jerks cannot be avoided. This leads to rapid fuel consumption and also adversely affects the operation of the car. By the way, not only new.

Before you start moving, you need to warm up the engine for several minutes (4-5 is enough) at low speeds of 1000-1200. In the automatic transmission, for warming up while driving, it is necessary to set the mode forcibly, which will not allow gear shifting further than the 2nd (with 4automatic transmission) and 3rd (with 6automatic transmission).

For running in a car, the optimal speed is from 80 to 115 km / h. On the track, it would be nice to try out your car, while not accelerating and not gaining more than 3000 rpm. And again, the speed should not be constant, every 10-15 minutes you need to change them. The level of gasoline and oil must be monitored every 100 kilometers. In general, make it a rule to check the level of fluids in the car daily. You can even look under the bottom - if there are any traces of oil on the asphalt.

Regularly inspect the car in case of breakdown, look under the hood, check the tires. If you really have to drive through busy city streets, try to gently press the pedals and monitor the speed - no higher than 2500 per minute. Take care of your car, do not accelerate sharply with the desire to test the promised high-speed result. An untested car will not be able to reach immediately high results, and such experiments will not do her good.

One thing to keep in mind while running important point- you need to break in the car only on good roads, off-road is not suitable for a new car. The first 500-1000 km. are so important to the engine, so be patient, and you can soon achieve the desired results.

All about the new car break-in procedure

After purchasing a new car, many people think about whether it is worth running in the car.

New " iron Horse» requires special care, some manufacturers indicate this in the manual. But it is worth remembering that its further fate will depend on the operating conditions of the machine during the break-in period. A run-in should take place not only a new car, but also a car on which the engine has been replaced or overhauled.

Engine break-in

The main condition for engine break-in is not to load the engine for the first 1,500 kilometers. Under heavy loads during this period, it can adversely affect the transmission and engine. Many manufacturers indicate that the engine should not run for a long time at one speed and avoid running the engine at the same speed for a long time. You should also avoid sudden jerks, sudden acceleration or braking.

Many experts believe that it will be optimal to keep the number of revolutions of the crankshaft in the range from two to four thousand. But during the break-in period, the number of revolutions should be less than three thousand.

In the instructions for the car, many write that working in neutral gear is difficult operating conditions, so use the car idling as little as possible. It is also desirable to exclude engine braking, as this overloads the main units of the car.

Petrol engine car

General recommendations to break in a car with a gasoline engine for the first thousand kilometers - do not exceed a speed of 90 km / h, do not use top gear and the engine speed should be below 3300-3500 rpm. Then gradually increase the load (revs and use of top gear) and by about 3,000 kilometers your car will be able to realize its performance characteristics.

Diesel engine car

Breaking in a diesel engine is more difficult. During the run of the first 1,500 kilometers, the revolutions should be below 2500, but at the same time above 1200. During break-in, it is not recommended to use idling, and during warm-up it is necessary to keep the engine crankshaft speed at 1200 rpm. Only after the break-in these restrictions are removed. Diesel engines run in two to three times more mileage than gasoline engines. After about 6,000 km, the car fully realizes its performance.

Running in not only the engine

Do not forget that a new car requires running-in not only the engine, but also other elements - transmission and brakes. Gear shifting must be done smoothly and avoid sharp pressing and “throws”.

Features of running in with automatic transmission

There are no break-in features with automatic transmission, but there are a few points that you should pay attention to:

Do not engage the highest gear (usually fourth).
Do not use neutral gear while driving.
Run in the countryside, because when driving in traffic jams, you can “kill” the box.
Change the oil in the gearbox after a run of 1000-2000 km.

How many kilometers to run

In different sources, there is a rather strong variation in mileage - from 1000 to 5000 kilometers. There is no consensus, but this information usually indicated by the manufacturer in the manual, although many dealers claim that it is not necessary to break in - their motto is "sit down and go."

Running in a new car Lada Granta

The break-in period is about 3000 km. It is during this period that the grinding and running in of more new parts takes place.

Rules to be followed in the first 3000 km of run:

Do not change the oil that was filled at the factory.
Tire pressure should be checked before every ride.
Do not allow the engine to run at an engine speed of more than 3000, as well as drive for a long time at the same speed. It is optimal to use the engine in the range from 2000 to 3000 rpm.
Correct transmission.
The running speed must be less than 100 km/h.
Do not use fifth gear during the first 1500 km of run.
Do not load the vehicle (do not tow other vehicles or trailers).
You can not brake and accelerate sharply.
Try not to allow the engine to idle.

Breaking in the brakes

The brakes of Lada Grants in the first 500 km need to be run-in. In order for the brake pads to “get used” correctly, sharp braking must be avoided. When rolling, it may be extraneous noise.

Transmission run-in

To grind the friction linings, you need to smoothly switch the gearbox speeds.

Running in Volkswagen Polo Sedan

During the break-in period, the main thing is not to overload the engine. It is better to spin the engine up to 4500 rpm with a minimum load than to drive loaded at 2000 rpm. At the same time, in the first 500 kilometers, you must adhere to uniform motion(no jerks, hard braking or sharp acceleration).

Mileage up to 500 km

In the first 50 kilometers it is better to drive in third gear at a speed of 40-50 km / h. Then you switch to fourth gear and accelerate to 60-70 km / h. At this speed, you need to drive 100-150 kilometers.

It is necessary to avoid sudden acceleration, as well as to reduce the gear and speed when driving uphill.

Mileage 500-1000

Now you can use fifth gear at speeds over 100 km / h. But movement is possible only on horizontal sections or “downhill”.

Mileage 1000-1500

Now you can increase the engine speed to 3500.

Mileage 1500-2000

During this break-in period, you can gradually load the engine. When accelerating, the rpm can go up to 4000.

Results

With such behavior during the run-in, the necessary statistics of the car’s behavior will be collected, which will be useful for service station specialists. It is also desirable to do TO at the end of the break-in run, which is called TO-0.

Running in the car Kia Rio 2013

The speed must not be less than indicated in the table.

Running-in at the car - the first 2500 km of operation. It is during this period that intensive running-in of parts takes place.

Movements should only be started in first gear at low speeds.

Avoid high speeds(less than 1150 km / h) and high speed (should be less than 4000).

Avoid driving in difficult conditions. This is a movement along deep snow, sand, ice, wet asphalt and another.

Do not tow other vehicles or a trailer.
It is necessary to monitor the temperature of the engine and the front wheel hubs. With signs of overheating or hypothermia, the causes must be immediately eliminated.
Monitor all fasteners and tighten them in time. These can be wheel mounts, steering rod joints, spring ladders, steering bipods, levers steering knuckles and the exhaust pipe of the muffler to the exhaust manifold of the engine.

Running in a new car Chevrolet Niva

When running in a new car, do not allow high engine speeds in the first thousand kilometers (for a diesel engine, in the first 1500 kilometers). Run-in with gasoline engine goes in the first 3000 km, and with diesel - 6000 km.

Avoid sudden acceleration or deceleration so that the moving parts get used to each other well.
Avoid sharp drops rotation of the crankshaft (engine speed).
Raise the RPM gradually as you run in.
If the machine will be used in urban areas, then the running-in should be greater.

Running in a new car Renault Duster

Avoid running the engine at idle (800-900 rpm).
In this case, you can not turn on the fifth gear on the manual transmission (fourth gear on the automatic transmission).
Try not to brake the engine.
Before driving, warm up the engine for several minutes at 1200-1500 rpm.
When driving, keep the speed in the range of 2000-2500.
Do not engage second gear until the engine is fully warmed up. In the APKK, you need to set the forced mode, so that the second gear does not turn on.
Do not make sudden jerks when moving. As well as sudden acceleration or braking.
If possible, avoid traffic in the city.

The ideal option for running the engine would be the track. On the track, do not shift above fourth gear and do not spin the engine above 3000 (the speed must be below 80 km / h). It is worth remembering that you need to constantly (every 10.15 minutes) change the speed (in the range of 2000-3000 rpm). Approximately every 100 kilometers, check the oil level in the engines, as well as other fluids, especially for leaks (just look under the car).

The first few hundred kilometers are very important for a car.

Transmission run-in

During the break-in period of the machine, it is prohibited to operate it off-road. It is also not recommended to connect in the first 500 kilometers of run front axle. Do not tow another car or trailer for the first 1000 km.

For a good "lapping" of the pads to the discs, sudden braking should be avoided.

Oil

At factories, “special” oil is poured without antifriction additives so that the parts quickly “roll in”. Therefore, it is recommended to change it after running in, as a lot of metal microparticles will appear in the oil. These microparticles can completely clog the engine oil filter and increase wear on a new engine. In this case, the manufacturer usually fills mineral oil, and at the first oil change, synthetic is already used.

Conclusion

A new car needs a lot of attention. For example, you need to check the oil level every day to avoid subsequent problems. It is also advisable to run the car on a good asphalt road.

Break-in of a new car, how many kilometers is a break-in of a car and whether a break-in is necessary. How to properly break in a new car. New car rules.

Today, cars that come off the factory line are more concise, with unusual designs and improved internal assembly. Improved internal mechanism requires a special approach, as well as strict adherence to operating recommendations. Gone are the days when the vehicle was omnivorous and unpretentious. Today, for full-fledged work The car needs a skillful initial run. More on this later in the article.

Breaking in a new car, what is it

Proper running-in of a new vehicle is a gentle driving mode, during which the car accelerates and defects are detected. It is required for grinding the engine elements, transmission gears and gearbox.

In addition, parts of running components, suspension and brakes are mastered.

Cold running in production, is cold running really done by the manufacturer

In general, running a car always raises a lot of questions from car owners. The problem is that at the time of purchasing a vehicle, showroom managers claim that there is no need to break in a new car with automatic transmission gears. Cold running-in of power units is carried out by the manufacturer even before they are installed in the engine compartment. Allegedly, this makes it possible not to waste your time on grinding in elements. In practice, there is no cold run-in, the car at the factory is checked only to detect defects. Therefore, you should not fall for such marketing ploys if you want the vehicle to serve for a long time. Only a proper break-in will help to avoid unforeseen costs for car repairs.

What really gives a car a break-in

After passing the initial testing in real conditions, the vehicle becomes more functional, achieving the following goals:

Incorrect and correct running-in of the car

It is unequivocally impossible to assert the need for a break-in, however, after the implementation of this event, the car owner receives additional guarantees that the unit will not fail prematurely. Many people think that running a vehicle is something very difficult, but if you rely on general rules break-in, the procedure becomes extremely simple. Remember, incorrect running-in of the power unit can lead to its breakdown.

Preparatory work for running in a new car

Before you start rolling, do the following:

Check the amount of engine oil - the level on the dipstick should be in the middle.
Make sure you have brake fluid and coolant.
fill the tank good fuel.
Check tire pressure.
Make sure there is no grease leak anywhere.

How many kilometers does a new car run in

Most car owners are concerned about the break-in intervals of a new vehicle. The time frame doesn't actually affect this, main criterion- the length of about three thousand kilometers. However, remember that this interval is not a general norm - mileage is individual for each brand. The length is set by the manufacturer and can vary from 1000 to 5000 kilometers. It is necessary to pay attention to the type of motor. If the vehicle is equipped diesel engine, the mileage is doubled.

Manual transmission, the process of running a new car with manual transmission, recommendations

For the procedure to be carried out with maximum benefit, you should rely on the following recommendations:

After the break-in is complete, change the engine oil as metal particles have accumulated in it.

Important! If the manufacturer has filled in the oil, do not change it before running in.

Running a car with an automatic transmission is very similar to running in a unit with a manual transmission. There are only a few differences that are associated with automatic transmission control:

Before starting, thoroughly warm up the gearbox, which is necessary so that gear lubricant got the right consistency.
You can not touch the kickdown mode.
Wheel slippage must not be allowed.
Make sure that it does not work while driving neutral gear, which can occur due to a decrease in oil pressure, which heats up and presses on the planetary gear.
It is not recommended to run a car in an urban environment, as sudden braking and movement changes are possible, which will adversely affect the “automatic”.
It is impossible to carry heavy luggage during the break-in process.
After running in, change the oil in the automatic transmission.

Don't forget that an automatic transmission requires more attention than a manual transmission. The design of the automatic transmission is much more complicated than the "mechanics". Therefore, the failure of any node will entail costly repairs. After running in, it is recommended to look into a car service, where to pass a technical inspection to detect flaws.

How to break through the base of the traffic police car

Today, cars that come off the factory line are more concise, with unusual designs and improved internal assembly. An improved internal mechanism requires a special approach, as well as strict adherence to operating recommendations. Gone are the days when the vehicle was omnivorous and unpretentious. Today, for the full operation of the car, a skillful initial run is necessary. More on this later in the article.

In addition, parts of running components, suspension and brakes are mastered.

Cold running in production, is cold running really done by the manufacturer

In general, running a car always raises a lot of questions from car owners. The problem is that at the time of purchasing a vehicle, showroom managers claim that there is no need to break in a new car with an automatic transmission. Cold running-in of power units is carried out by the manufacturer even before they are installed in the engine compartment. Allegedly, this makes it possible not to waste your time on grinding in elements. In practice, there is no cold run-in, the car at the factory is checked only to detect defects. Therefore, you should not fall for such marketing tricks if you want the vehicle to last for a long time. Only a proper break-in will help to avoid unforeseen costs for car repairs.

What really gives a car a break-in

After passing the initial testing in real conditions, the vehicle becomes more functional, achieving the following goals:

The moving elements of the system will be rubbed.
The roughness and flaws of the parts will be smoothed out.
Lubrication pipes, as well as the entire mechanism of the power unit, will be cleaned of chips and other foreign bodies.
Brake pads and discs wear in and get good braking after 200-250 kilometers.
Tires will improve.
Marriage or existing defects will become noticeable.

Most often, the happy owners of a newly purchased car literally blow off dust particles from it, but Special attention should be given to the "heart" of the machine. New engine, or a motor that has recently survived overhaul need gentle maintenance. and only after running-in can they be used in standard mode with all the required loads.

What is engine break-in

It is customary to call a motor running in the process of grinding in parts that constantly interact with each other, working at high temperatures. In fact, all mechanisms that have mating moving parts must go through a run-in, because only in this way, having worked under a small load, they will be able to “prepare” for the conditions in which they will have to work throughout their entire service life. Simply put, the moderate friction that is created helps the parts to take the final shape, and in the future it should not change significantly.

The first and most important stage of running-in the power unit takes place within a few hours after it is installed on the vehicle. So, during the first start-up, the compression and oil scraper rings are lapped, which are in contact with the cylinder wall. Special name to define this process we do not, while English-speaking countries use two different terms at once. The first step is called "engine break-in"(it can be translated as “commissioning”), and the subsequent final processing is called “engine run-in”, which, in fact, provides for the direct running of moving parts.

It should be noted that there is no universal instruction that would explain exactly how the engine should be run in. Moreover, most car owners do not need to deal with this process on their own, since all the necessary manipulations are performed by specialists at the factory, and the car comes to the buyer with an already run-in engine and filled with oil. However, a certain amount of information is still available. In particular, on the issue of the degree of load during the engine break-in period, the opinions of experts from various manufacturers differ somewhat. Oddly enough, the lack of agreement here is due to the overall increase in productivity over the past few years.

The fact is that the quality of engine parts has improved significantly, although the consequences of incorrect commissioning are still observed today. If on old power plants to find the cause of the breakdown could ordinary mechanic, then for good orientation in modern cases of engine damage due to incorrect running-in, a specialist must have considerable knowledge in the field of physics.

Cars produced today differ from their ancestors in their high sensitivity to the quality of fuel and oil recommended by the manufacturer. Therefore, engine break-in should only be performed using fluids specified in the vehicle's technical manual.

Interesting fact!Most big engines- ships. The diameter of their 14 cylinders corresponds to 960 mm, and the power of the installation reaches 108920 hp.

What is engine break-in

To perform lapping of parts of a new or just overhauled engine, it is best to use a special stand that will help you obtain the most reliable data on the condition and activity of all units of the unit. However, this is not the only option carrying out a similar procedure, and the engine running in can be performed in other ways (meaning after the overhaul of the power unit). But first things first.

Cold running, for which the stand is used, provides for connecting the engine to the electric motor using a coupling. The latter can change the speed, which allows you to run the engine in a soft mode. Job this device controlled special program installed on the stand's computer. It also receives data from the sensors, processes them and selects the rotation mode. These sensors take temperature readings, thereby preventing the engine from overheating.

Cold engine break-in using a stand is the most acceptable technology that allows you to get a high-quality result and good grinding of parts. power plant. However, you need to understand that for such a procedure you will have to pay a certain amount of money. If you have no desire to turn to specialists who have the above equipment, then you can use another method of cold running (without a stand).

In this case, the rotation of the engine will occur due to the transmission from the side of the wheels of the car (the car is hooked to another vehicle and towed in third gear without turning on the engine). In addition, the system must have enough oil necessary for effective break-in, and coolant.

I must say that the described version of cold grinding is very far from ideal, since it is difficult to control the heating of the rubbing surfaces of the motor. Hot-type engine break-in is often used (the car stays in one place all the time, but the engine continues to work). The same option is used when working with the stand, only in this case hot lapping is performed on removed motor. To begin with, the engine is allowed to idle (no more than 3 minutes), and then it is turned off and allowed to cool completely.

The procedure should be repeated several times, and after the completion of short cycles, the unit starts up for a longer time (40-50 minutes) in the mode idle move. This process requires control temperature indicators(should not exceed 80 ° C), and as soon as the temperature begins to rise, the engine is turned off. The increase in turnover occurs gradually.

Note!The motor must necessarily cool down, otherwise a permanent effect high temperature can lead to thermal deformation of rubbing parts and loss of oil viscosity.

by the most in a simple way engine break-in is a natural grinding of parts. It should start with driving at a speed of no more than 40 km / h during the first 50 km of the journey, which is quite difficult in urban conditions (traffic lights and “traffic jams” are often encountered on the driver’s path), which means running in is best outside the city, and no more than in third gear. Having overcome the specified distance, you can increase the speed to 60 km / h, having traveled 200 km in this mode, and then increase the speed by 10 km / h after every 100 km of the car's run. However, do not forget that until the car has covered 2000 km, it is not advised to raise the speed above 90 km / h.

Despite the apparent complexity of the process, you should not have the question “why do you need an engine break-in and is it needed at all”, because by following this procedure, you will ensure a long “life” for your motor.

When to do a spin

running-in car engine carried out in two cases: after installing a new engine on a vehicle and after a major overhaul of the old power unit.

On a new car

The “primary” running-in is performed by the specialists of the car manufacturer, and the further “well-being” of the car largely depends on the thoroughness of this procedure. However, there are cases when the manufacturer declares that there is no need to run in the released vehicle.

Most likely, in this case, the experts calculated that the harm from the suboptimal operating mode of the new car is so insignificant that it is not worth reporting it to the buyer. Of course, you can heed these recommendations, but it would be better if you still take care of your vehicle, at least in the initial stages of operation.

Note!Despite widespread opinion, new motor do not run in by running for a long time at one speed. This procedure will lead to highly specialized grinding of parts, so when you start to operate the car in normal mode, it will be re-burned in, which is fraught with additional wear of the elements.

When running the engine, you should also avoid sudden acceleration and its operation on maximum speed or values close to them. Permissible value revolutions for specific model you will find in the user manual.

After engine overhaul

Any part of the power plant that has recently been overhauled (it doesn’t matter if cylinders, bores or shaft surfaces have been bored) needs a certain amount of time to run in the mates.

Often, the primary break-in for most automotive friction pairs is performed during the first 2-3 thousand kilometers, which, however, is not the end of this procedure, but is only considered the starting point for a smooth increase in load. Depending on the quality of the replaced parts and the repair itself, the final break-in usually takes place up to 10-15 thousand kilometers. Only after this figure can the motor be required to display maximum performance.

It should be noted that the running-in of rubbing pairs is always accompanied by increased heating, which explains the need for a new or repaired engine to run in at reduced crankshaft speeds (up to 60% of the nominal values). Also a prerequisite is the use of fuels and lubricants recommended by the manufacturer. An incorrectly run-in power unit often has a resource that does not exceed 30% of the calculated value included in its design by the manufacturer.

A common problem when running in an engine after a major overhaul is the installation of new rings in worn piston grooves. If they are badly broken, the probability of breakage of the rings at the first start of the engine increases significantly.

Groove wear is assessed visually, simply by examining the old ring. If its lower part turned out to be glossy, it plays a little waviness in the sun, and when you run your finger along it, you will feel wear steps, then the pistons will have to be changed without fail. In most cases, the grooves in the pistons are worn in such a way that their lower surface tilts down slightly. For this reason, the bearing surface of the old ring wears at the same angle. When installing a new ring, it will begin to curl and, most often, quickly fail.

Do you know?The shape of the piston is not as strictly cylindrical as it might seem at first glance. If you look at the part from the side, you will notice that it is more barrel-shaped, and if you look at it from above, it will most likely resemble an oval. During operation, the piston heats up and acquires the correct shape.

How to break in the engine

There are few rules for running the engine. The first and most important of them is not to load the car. No need to ride at high speeds or transport in vehicle excessive amount of cargo (passengers), slow down abruptly and move in low gears. These rules should be observed up to 1500-2000 kilometers.

In the case of poor-quality work of the power plant, a lot of trouble awaits you. These include: oil getting into the air cleaner increased consumption fuel fluid, engine starting problems, etc. Therefore, if you recently purchased a car or made a major overhaul of the motor, be sure to follow these rules.
