advances folding minds for robotic engine.

This is due to the fact that the leather part, although it is prepared on a high-precision machine, leaks the moisture structure of the surface, thereby creating greater rubbing pressure.

This effect is corrected over a period of several hours of operation, but in order to preserve the maximum resource of the repaired unit, it is necessary to follow all the rules and how to run in a new or repaired engine.

Therefore, this article will describe all the methods and report recommendations for operating the engine of the same car during the first few kilometers after a major overhaul. Keeping these up to date will help preserve the engine's useful life even more. Also ensure the quality of the components.

Naturally, in such an important element of the car as the engine, parts are installed

original spare parts

, or obviously beautiful yakost. Otherwise, proper running-in will not prevent another repair in the near future.);

This article is insured for new, technically serviced vehicles, so that, according to the master, we are well aware of all the nuances of running-in, and we ourselves can be pleased with how we carry them out, or we carry them out ourselves but on the bench it is owned in the master.

Renewal of engine running-in

Most often, it becomes stagnant when the engine is running in.

In this case, the methods are only available to specialized stations. possible malfunctions or inaccuracies in the robot power unit, are revealed and corrected at an early stage.

Cold grinding, this method is called through the principle of robotic stand. Having installed the motor in a special place, its crankshaft is connected to the electric motor, which is also an element that transmits torque to the crankshaft. Next, automobile oil is poured into the engine

good juiciness

and the refrigeration system is connected.

The speed and characteristics of the robotic motor are controlled by additional electronics, which turns off most of the fallout in the grinder, while the entire stand works according to a predetermined algorithm.

Cold run-in without a stand

This method is the best way to repeat the principle of robotic bench installation. It is based on the fact that the engine is more likely to be rubbed in, because it does not warm up due to the presence of substitute gasoline or other combustion, and the wrapping is provided by external devices. The whole principle is very simple.

The car is placed on a tow rope behind another and pulled in third gear for several years.

This helps to quickly run in the engine, but also includes any control over the process and the adjustment of various algorithms.

And the success of the procedure can be judged after an hour or so of mileage before the actual repair.

There are a number of ways to determine the success of breaking in a car, and when using the cold method, these signs are especially noticeable:

The engine starts to work well and has stable trim

After a cycle of short starts, which allows for the cleaning or initial grinding of parts, the engine is started for one year. Over the course of a year, the engine wraps move step by step, as a result of the procedure, the engine wraps do not have to move half the maximum allowable for this unit..

During this procedure, you must monitor the temperature of the engine, and if it exceeds the norm, carefully turn off the engine, and after cooling, repeat the process from scratch.

Also, it is necessary to keep an eye on the liquid and cooling medium, and carefully check all connections and gaskets for possible thread

technical areas

Now you can note that the running-in of the engine after a major overhaul has been completed.

This means that it is recommended to undergo another natural run-in - this will guarantee the result of thorough rubbing of all engine elements. Running in the engine is natural This method is the simplest and requires careful operation of the vehicle for the first 2,000 kilometers.

In this case, when driving a car, it is necessary to be careful and follow the basic rules. This includes carrying out natural running-in, which is recommended not only for cars with engines after major repairs, but also for new cars off the production line. With a distance of the first 2,000 km, it is not possible to accelerate the car more than 70-80 km/year, and the number of crankshaft wraps per shaft should not exceed 2,500. and you won’t “mess around”" with a car at the garage. It is also not possible to quickly accelerate the car to the recommended speed, galvanize the engine and re-vanish the car. It is also necessary to steadily follow the line

Also, after completing the running-in of the engine, it is necessary to carry out a technical inspection to check all the important components of the engine, which includes checking the gas timing belt, alternator belt and other elements.

new car

don't break it in.

It is very significant: in the operating instructions for many modern cars it is written: “the car does not need to be broken in.”

If you believe it, let’s try to get married.

Why was a car run-in required?

Over the next few hours, cars, engines, gearboxes, and chassis components have appeared.

etc.

required a difficult and tedious break-in procedure.

Going into detail, this procedure was reduced to the point that the first 5-10 thousand kilometers of water were categorically prohibited from sharply accelerating, sharply gallivanting, shifting into gear, driving uphill and downhill , it was punishable to change the oil every few kilometers and much more.

All this was done to ensure that all the abraded surfaces of the car parts were polished, and the metal shavings that appeared as a result were covered in oil and had to be replaced.

Since the “grinding of parts” is accompanied by increased heating, the car is guilty of producing low levels of performance and low performance.

Increased accuracy of parts, improved production culture, advanced technological procedures - all this led to the appearance in the operating instructions of the inscription “the vehicle does not need to be broken in.”

And it would be true that it would not be like that. Nowadays, car parts are manufactured in factories car brands

This involves a large number of contractors in different parts of the world, and they have their own contractors.

When folding brandy, it is important to control the bitterness, but the seriality of fermentation imposes its limits.

And, as you know, the last one is your favorite meal (“do you remember the phone number?”).

And even when folded into the engine, it is possible to consume the saw blade.

The high culture of production of cars from German and Japanese brands reduces this ability to insignificant importance.

Ale won will still be lost.

Before that, not only the car’s engine will require break-in - the tires and brake pads will also need break-in.

As an argument for the speed of break-in, we quote from the operating instructions: Hyundai To extend the service life of your car, it is recommended to make the following visits:

In order to ensure the reliability and durability of the vehicle in operation, during the first 600 km of driving, it is necessary to adhere to the following rules: Do not destroy the place with full throttle, avoid sudden accelerations.

Don't be too harsh.

A normal run of new galvanized pads is expected to cover a distance of 300 km, for as long as possible, galvanize smoothly and at medium intensity.

After repairing or replacing the engine, as well as after replacing the brake pads, it is necessary to follow similar recommendations.

So what if BMW doesn’t care for its cars?

And those dealers, who write “the car will not require running-in”, seem to be lying?

How everything turns out to be true But in reality, everything is more complicated.І BMW says that (although it is recommended to break in the car), and the phrase “break-in will not be required” is also valid.

On the right is that it’s classic to break in a car, which was necessary for hours Radyansky Union, the truth went in the past.

There is no longer any need to change every thousand kilometers (it is enough to go through “zero maintenance”), there is no need to urge yourself to switch to a higher gear then.

This kind of running-in is no longer necessary.

Suchasne obladnannya

Allows you to bet that you get parts of such quality that it allows you to get by without running in the engine.

And dealers who are victorious in such ownership may not have to worry about their cars.
Tim, no less, must use the car sparingly (which is also reflected in the above quotes).
And the axle requires extensive running-in for cars, which were manufactured with less or less ownership (we won’t name brands) - the power is deprived of moisture.
Therefore, we will introduce a bunch of dirty rules for running in a car.
Rules for running a car
It is necessary to warm up the engine (at least 4-5 hours at idle).
Do not start abruptly, galvanize abruptly, overdrive the car, drive off-road, uphill, galvanize the engine.
Do not overestimate the speed of 100-110 km/year.

It is necessary to note that for European cars in Europe they often do not indicate “zero maintenance”, but recommend arriving immediately at the first maintenance – after 15 to 20 thousand. km.

In addition, the frequency of oil replacement will increase to 20-25 thousand. km.

Everything is connected both with the presence of oil in the car, and with the addition of oil, burning, and more gentle operation.

Our realities still require great care. Pouch European ones

Japanese cars

Break-in is practically not required - it is enough to follow the gentle regime prescribed in the operating manual.

It’s written in the owner’s manual that “the car will not require running in” - still, for the first thousand kilometers, operate the car in a gentle mode. The need for running-in is directly proportional to the quality of the vehicle's production. And if you don’t run-in a car with an incorrect condition, nothing good will happen.

Most often, the happy owners of a sweetly purchased car literally blow powder from it, but

especially respect

The trace is added to the very “heart” of the machine. A new engine, or a motor that has recently undergone a major overhaul, will require careful use. And only after running-in can be changed from the standard mode with all the necessary adjustments. What is it like to run in an engine? Engine running-in is usually called the process of grinding parts that constantly interact with each other, operating in high-temperature sinks. In fact, all the mechanisms that move the parts that turn out are subject to running-in, and even those who have practiced under little training can be “prepared” for the minds in which they will have to work this term of service. Simply put, gently rubbing what is being created helps the parts to take on the remaining shape, and then there is no need to change completely.

The first and most important stage of running-in the power unit must pass several years after its installation on the transport unit. Thus, during the first start-up, the compression and, as if I explained how the engine may be running in, I still can’t sleep.

Moreover, most car owners do not need to deal with this process on their own, since all the necessary manipulations are completed by the mechanics at the factory, and before purchasing the car, the engine will have already been run in and filled with oil.

However, there is still a lot of information.

Zokrema, at a nutritional level of importance during the period of engine running-in, the thoughts of experts from various engine companies differ widely.It’s not surprising that the ubiquity here is explained by the hidden improvements in the productivity of the remaining few rocks.

On the right, the fluidity of engine parts has significantly improved, although the legacy of incorrect commissioning is still being guarded today.

If on old power plants it is possible to identify the cause of the breakdown by the primary mechanic, then for a good orientation in the current breakdowns of the engine through incorrect running-in, the mechanics are responsible for their knowledge in the field of physics.

Cars that are produced today are similar to their ancestors with a high sensitivity to the harshness of fuel and oil recommended by the manufacturer.

Therefore, the running-in of the Varto engine is limited to the special requirements assigned to the technical assistant for the operation of the transport unit. Great fact!.

However, you need to understand that you will have to pay a penny for such a procedure.

Since you don’t have to worry about the fears that you may have in possession, then you can use another method of cold running in (without a stand). In this type, the engine wraps around the gearbox on the side of the car’s wheels (the car is parked before another vehicle and skids in third gear without the engine turning on). In addition, the system requires a sufficient amount of oil, which is necessary for effective break-in, and a cooling medium. It must be said that the description of the cold rubbing option is far from ideal, since it is difficult to control the heating of the surface of the motor that is rubbing.

It is often necessary to test and run in a hot type engine (the machine remains stationary at one point, but the engine continues to run).

This option should be used when working with a stand, only in this case it should be hot rubbed on the removed motor.To start the engine, give it a spin

at unarmed speeds (no more than 3 minutes), and then turn it off and allow the surface to cool down. The procedure is repeated several times, and after completing the short-hour cycles, the unit starts for more than three hours (40-50 hours) in idle mode. In this process, you need to control the temperature indicators (you don’t have to exceed 80 ° C), and when the temperature starts to rise, turn off the engine. The increase in turnover is achieved step by step. Increase your respect!

Regardless of the complexity of the process, which appears to be the case, you don’t have to worry about why the engine needs to be broken in and why it needs to be fired up, since by following the prescribed procedure, you will ensure that your engine has a long life.

If you need a robiti run-in

Break-in car engine carried out in two situations: after installing a new engine in a transport unit and after a major overhaul of the old power unit.

On a new car

The “first” running-in is carried out by the car manufacturer, and due to the urgency of carrying out this procedure, there is a lot to be done to protect the “self-esteem” of the car.

Problems are eliminated if the manufacturer declares that there is no need to run in the released vehicle.

This option should be used when working with a stand, only in this case it should be hot rubbed on the removed motor.For all that, the fahivtsi said that the damage caused by the suboptimal operating mode of the new car is so insignificant that it is not good to inform the buyer about it. Of course, you can listen to these recommendations, or even better, if you still save your transport costs, at least at the initial stages of operation. Without regard for broad thoughts,

new motor

It’s not good to wrap a shlyah around a tattered robot on just wrappers.

A procedure has been specified to carry out highly specialized grinding of parts, so that if you decide to operate the car in emergency mode, you will have a second gear that threatens additional wear of the elements.

After running in the engine, it is also necessary to avoid sudden acceleration and operation at maximum rpm or values close to them.

recommended by the virobnik.

If the power unit is not run in correctly, it often loses a resource that does not exceed 30% of the capacity 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 near the worn piston grooves.

Since the engine is heavily damaged, the risk of ring failure when the engine is started for the first time increases significantly.The weariness of the groove can be assessed visually by simply looking at the old ring.

Since the lower part is glossy, a little shines with a slight limpness, and when you run your finger you can see wear and tear, then the pistons will have to be replaced in order.

In most bearings, the grooves in the pistons wear out so that the lower surface of the pistons slides down. Therefore, the supporting surface of the old ring wears out under the same coat. When a new ring is installed, it will begin to curl up and, most often, will come out of alignment. What do you know?

The shape of the piston is not as cylindrical as you might think at first glance. If you look at the detail from the side, you will notice that it has a more barrel-like shape, and if you look at the animal, then you will notice that it is an oval. During the robotic process, the piston heats up and takes on the correct shape. How to properly break in the engine There are not many rules for running an engine. First and foremost, don’t vantage the car. There is no need to drive at high speeds or transport in transport service

The car engine is a folding unit, in which hundreds of elements are required to ensure that its characteristics correspond to the stated ones.

When buying a car this month, we are first to be amazed at the engine, its strength and the performance of similar models of engines as compared to other models of identical power units. Often on forums, social measures And on websites on the Internet you can focus on super-sensitive input for a specific engine.

Some people say that they can travel hundreds of thousands of kilometers without problems, while others say that the engine can quickly go wrong.
The smells are tested on the basis of evidence, and their results vary according to:
A batch of parts that will be purchased from the engine;
It is important to check the engine before installing it on the vehicle;

Manners of water;

Most often, the happy owners of a sweetly purchased car literally blow powder from it, but

Initial running-in of the engine. The remaining point of many car buyers is given little respect, but nothing. Proper engine running-in is necessary to prolong the service life of your units.

Break-in is popularly known as acceptable operating modes for the first few thousand kilometers, as the vehicle manufacturer most often indicates in technical care.

I thought, what

current cars do not require running-in of the engine, just in case. Based on improved technologies for the production of automobile elements, it is ideal to collect an engine from time to time. Here we come to the definition of “running in”.

Below you will understand the process of rubbing car parts one by one. Most often, running-in is considered in the aspect of the engine, but on a new car the suspension, linings and other units are also necessary. As the machine operates for the first few thousand kilometers, the parts in it are added to, so that they grind in one by one.

If you are ready to try out a new car, do not allow any sudden movements during the break-in period.

Naturally, many drivers want to verify that the car can gain speed from 0 to 100 kilometers per year as stated by the manufacturer between hours.

It is unlikely that you will be able to earn money on a new engine, and in a stressful situation you will lose money, which may affect your durability.

Running in the car engine after repair

Not only new engines require break-in. It is necessary to supply an engine in which a number of parts have been replaced with new ones, since they mechanically interact with the old elements.

Thus, replacing the washer reservoir, sensors and similar parts does not require running in the engine after repair, even if new mechanical elements are installed: liners, pistons, rings and others, run in the engine.

How to break in an engine for a long time after repair

Depending on the complexity of the work that was completed during engine repair, the difficulty of running in the engine varies.

You can mentally divide the triviality of running-in into the next step: The process of running in the engine after repair is in no way different from running in a new engine, except for the first start.

Yak Vikonati first engine start after repair
So, post-repair starting of the engine is an important process, especially if the repair is not a major one, but key parts have been changed.

To make the first engine start as smooth as possible, you need to check the following points:

Important:

The hot and cold running-in became the widest.

During a hot run-in, the engine runs directly on the car, in Russia, and during a cold run-in, an electric motor is connected to the engine, which wraps the power unit.

Major engine repairs at a car service center do not include cold running-in, since not all engines are equipped with such running-in stands.

He will have to break in the engine himself with water. To correctly perform the break-in, you must become familiar with the procedure for carrying out this procedure so as not to violate the term of break-in. Features of running-in It is impossible to confuse such concepts as refurbishment of the engine and its major overhaul. Whenever the engine is rebuilt, several operations are completed: replacing oil seals and liners.

And major repairs involve external disassembly, defective inspection, and replacement of damaged and worn parts, their adaptation to the required dimensions.

Before such work comes: grinding.

collapsible shaft

, installation of new

connecting rod bearings
, boring block, etc.
Major repairs are not cheap and are carried out only by professional specialists.
As a result, the car manufacturer selects engine upgrades, which include the parameters of the new power unit.

The break-in rules are identical for both new and refurbished engines.

The installation of new parts, as well as damaged surfaces, requires the grinding of parts for further work.

Grinding is used for updating the engines of the cylinder-piston group, crankshaft and connecting rods, gas distribution mechanism.

The engine will need to be broken in for at least 3000 km.
If the repair is only on the distributor and the head of the cylinder block, then run in 1000 km.
The most popular overhaul has become an option due to recent engine upgrades, which is obvious.
Before starting the engine, warm up the engine at idle speed, then warm it up for an hour to operating temperature.
It’s best to plan your route ahead of time in such a way that the road surface is smooth without any big ups and downs.
It is important to ensure that there is no water near the car.

During the hour, it is necessary to block the engine, galvanize it sharply and squat, and prevent jerking. It is not recommended to accelerate more than 60 km per year, or to increase engine speed above 2500 rpm. It is impossible to allow the tension to slip, as well as frequent slippage at low speeds, with the engine wrapping around 1000 rpm.

Driving with monotonous demands on the engine cannot be allowed. In other words, it is not recommended to run one transmission for an extended period of time.

It is better to smoothly change gears, sometimes accelerating and galmic, but in this case it is necessary to correctly select the gearbox so that the engine operates in the interval of average speeds.

This method makes it possible
piston rings find your place in the piston grooves, and the cylinder mirror is opened. The best light polishing will not be able to perfectly smooth out all the roughness that can be easily removed by running in.
Mastila and cooling liquids cannot be poured into the liquid, as the debris from the liquid will lead to leaks and various malfunctions.
After starting the engine, the vise must reach its normal value when running unarmed.
It is not possible to add gas because the pressure does not return to normal and the control lamp does not go out.
In this case, the engine needs to be turned off.
Restart the engine.
In the same situation, it is necessary to find out what is wrong with the oil system.

If you continue to operate the engine without a working vice, you will have to start a major overhaul of the engine again. Once the pressure on the lubricant system quickly returns to normal, you can warm up the engine. At elevated temperatures, the oil becomes rare, which is why the pressure drops slightly and reaches the working indicators, or not less than 0.8 kg per cm 2. As the engine warms up, it is important to carry out a visual inspection to clearly identify the flow of oil and various operating conditions. If there are leaks, then the engine starts to slip and the problem of leakage arises.

With normal pressure and a dry engine, free from leakage, and running smoothly, it is recommended to listen to the engine for extraneous noise.

The normal operation of the engine means that you can begin running-in. Enjoy a short trip, being careful at what cost control lamp

vice in the oil system, as well as the temperature of the power unit according to fitting panels.

It is also necessary to ensure that after the cylinders are turned to repair dimensions, the parts often have to stagnate with a thick oil, aligned with a new engine.

The most accurate and correct method for grinding new parts on a repair engine is cold running on special installation.

For this purpose, there is a special stand, which is not available at all car service centers and technical service stations. This allows you to clearly and quickly carry out the engine break-in procedure. In this case, closer control is carried out over the functioning of the motor, and inaccuracies that arise and malfunctions in the operation are eliminated during the running-in process.

This method is also called cold rubbing, following the principle of its action on the stand.

Having fixed the engine in place, its component shaft is connected to the electric motor, which is driven and transmits the torque to the car engine.

Then the power unit is filled with motor oil of a suitable brand, and the cooling system is activated. The parameters and characteristics of the robotic engine are checked for additional assistance.

electronic system

control, which allows you to turn off the grinders at the hour of running-in, while the stand operates under the adjusted program.
Stand-less cold run-in
This method has the potential to cause problems with the work of the rolling stand.

And the success of the procedure can be judged after an hour or so of mileage before the actual repair.

This is the most popular method that is used in motor repair shops and by certified specialists.

Sometimes the tires are victorious at once due to natural running-in.

The procedure is completed at idle speed, but with a different number of revolutions of the engine and with different ranges of its functioning.

Start the engine for a short hour until it exceeds 3 turns.

This process is repeated several times. Between these starts, the engine must be allowed to cool down, otherwise the engine can overheat due to rubbing of parts. After completing a cycle of short-hour starts, which allows for initial or thorough grinding of parts, the engine starts for 1 year. During this period, the engine's rotation speed increases significantly, and then, at the end of the process, the revolutions will not be more than half the maximum permissible revolutions for this type of power unit. At the end of the procedure, you need to keep an eye on the engine heating, and if the temperature is too high, you will need to terminate the engine, and then, once cooled down, shut down all operations again.

It is necessary to keep an eye on the oil and antifreeze, stitch on all gaskets and floors to ensure there is no leakage. After this test run-in was carried out. It should be said that the mechanics are pleased to carry out the same natural running-in, in order to guarantee the complete refinement of all engine parts.

There are great benefits in the running-in procedure for gasoline vehicles.
diesel cars
no. To reduce engine friction, an oil system is installed. Oil pump
pumps the required pressure, which is pumped into motor oil through the oil channels and parts that rub.
Between them a spit of olive is created, which is popularly called an olive wedge.
It’s better to break in the car one by one, so you won’t need to stand at traffic lights and check it often.
In Russia, on a straight line, you can engage fourth gear and roll with speed, which does not exceed 80 km per year.

When going uphill, it’s better to switch to a lower gear. It is recommended to revise the engine at least 2 times during one trip and turn off the engine to allow it to cool down, check the level of oil and allow it to cool down. If possible, it is necessary to check the oil in

automatic transmission . After checking the oil, do not close the hood yet, start the engine and listen to the sound of the robot, test the electrical installation of the robot. Such checks must be carried out before the mileage reaches 1000 km. This is the minimum mileage of the diesel engine for running-in.
