Does the car really have a break in period? Is there a run in period for the current car?

The earliest reason for the car run-in period is that the production process level and manufacturing accuracy of the car are not high enough, and there are some small defects on the uneven surface between the precision parts inside the engine and the gearbox, so it is not suitable for the driving mode of full power, and it is necessary to use the run-in period to achieve "self-adjustment" between the various parts, and the uneven small defects on the surface of each other are worn away, and slowly become a smooth and wear-resistant surface, so that the later use will have better durability and stronger bearing capacity. If the new car has not been run-in, long-term high-load driving will make the vehicle parts can not be run-in, and finally will affect the life of the vehicle.

With the improvement of mechanical processes, the level of design accuracy between parts is far higher than it was a decade ago. Most of the parts of the new car have been accurately calculated and cooperated, the level of car manufacturing technology and manufacturing accuracy have been greatly improved, and the surface between the internal parts has been smooth and wear-resistant. To put it simply, the manufacturing process of the car factory can meet the needs of the military industry, and the technology of lubricating oil has also improved, and the protection of parts and components has been quite high.

Nowadays, more and more car manuals do not require the vehicle to be run-in, of course, some conservative manufacturer manuals still require the owner to drive gently, such as avoiding emergency braking within 1000km, avoiding high-load engine work, etc. However, most automobile manufacturers have no requirements for running-in. Therefore, the current new car basically does not need a run-in period.

Due to processing and assembly errors, the frictional resistance of the moving parts of the new car is always much greater than normal when it starts to run, and the running-in (also known as walking) effect in the early stage of the car will have a great impact on the service life, working reliability and economy of the car. Therefore, the run-in regulations must be strictly implemented when using new cars.

1. Run-in regulations for new cars within 1000 kilometers:

1) Never drive at full speed.

2) - Generally not to drive at a speed of more than 100 km/h.

3) Avoid driving at high speeds in all gears.

2) The run-in of the vehicle between 1,000 and 15,000 km: it can be gradually increased to the maximum speed or at the maximum permissible speed of the engine.

2. After the run-in period, attention should be paid to:

1) When driving a car with a tachometer and shifting into the approaching high speed, the maximum engine speed allowed for a short time is 5 500 rpm when the pointer reaches the red indication zone at the latest. The maximum permissible speed in each gear is 40 kmh in the first gear, 65 kmh in the second gear, 100 kmh in the third gear, 135 km/h in the fourth gear, and 165 kmh in the fifth gear.

2) Avoid running the engine at unnecessarily high revs, and switch to high gear early to save fuel and reduce noise.

3) Do not drive the engine speed too low, and only change to low gear when the engine is working hard.

4) The speeds and rotational speeds listed in the instructions are only applicable to engines with normal temperatures. When driving cold, do not allow the engine to work at its highest revs, whether in neutral or in any other gear.

5) New tires don't have optimal adhesion when they start with use, so new tires also need to be walked, slower for the first 100 km, and driven with care.

6) The new brake friction pads also need to be run in, in the first 200 kilometers of driving, there is not yet the ideal friction, at this stage if the braking effect is slightly worse, you can appropriately increase the pressure of the pedal. The same is true after each subsequent replacement of the brake pads.

7) Under possible conditions, long-term continuous driving should be avoided during the run-in of the new car, so as to avoid the continuous working time of the engine and chassis parts for too long, resulting in aggravated wear and tear of the parts, which will directly affect the service life of the car. It is also necessary to avoid running at full load, generally in the first 1000 kilometers of driving, it is best to run below 80% of the rated load. Also, try to avoid driving at high speeds and don't go faster than 70% of the top speed with the throttle open for the first 2,000 km/h.

8) During the run-in of the new car, the driver should heat up in situ after the new car starts at the beginning, and then start after the water temperature rises to the working temperature range, and should choose a good road surface during driving, and slow down when the road conditions are poor; When driving, the throttle should be smaller, the operation should be light, once the engine or chassis sound is found to be abnormal, it should be stopped to check the fault in the embryonic period. <>

The description of the run-in period is generally not to drive at full throttle; The engine speed cannot exceed two-thirds of the rated speed; The trailer cannot be towed; The speed of the vehicle shall not exceed 110kmh or 120kmh; Tires and brake pads need to be run-in.

The so-called full throttle is what the little partner calls "floor oil". But this is a foot in the money, who will have nothing to do this when driving every day? Let's talk about the speed again, the so-called speed can not exceed two-thirds, that is, almost 5000rpm, what is the concept, some cars even if you step on the floor oil may not reach this number.

As for not being able to tow a trailer, it seems that if you drive like this on the land of China, there will be police officers coming to your door, and basically they will not drive like this. The speed of the vehicle cannot exceed 120km h, in fact, the high-speed speed limit is this value, and it will not be exceeded by ordinary driving, especially in urban areas. Finally, when it comes to tires and brake pads, the general manual will explain that the grip has not yet reached a good state in the first few hundred kilometers; The braking power of the brake pads in the first few hundred kilometers has not yet reached a good state.

But this little friend still wants it, but don't worry too much, as long as you drive normally, it's no problem. <>

Is there a "break-in period" for new cars now?

Does the current new car still need to be run-in? Regarding the run-in period of a new car, you may have heard a lot of such words: the accelerator and brake should be gentle, not too fast, do not go at high speed, and try to keep moving forward at a constant speed, otherwise it will hurt the vehicle engine and so on.

But there are also many old drivers who say that it doesn't matter, rest assured to drive boldly, and now there is no run-in period for new cars, and they can be used normally at will. So what should we do with our new cars, and do new cars need a run-in period?

The degree of fit between the various parts of the new car needs to be run-in.

Now the manufacturing process of automobiles is indeed much more advanced than before, and it will be run-in in advance before leaving the factory, and there is no need to go through a complex and long run-in period as before, but this does not mean that there is no need for run-in at all. When a new car is just starting to be used, the fit between the various parts is relatively jerky, and there will still be some debris that is not completely polished and smooth, which requires a certain run-in period.

There is also a need for a run-in between people and cars.

When you just get a new car, the owner also needs to have an adaptation process to understand and familiarize yourself with the performance of the vehicle, which is also the run-in period - the run-in between people and cars. Before fully mastering the nature of the vehicle, it is recommended that the driver should drive cautiously to avoid misoperation, and the speed of the vehicle should not be too fast, so that he can also give himself a time to react.

During the run-in period, the vehicle should not drive too fast, of course, there is no problem at all on the highway. Don't brake too hard, take a little care. In fact, these matters should be paid attention to even after the run-in period.

In addition, the new car is within 5000 kilometers, because there are impurities falling, the oil is easy to become dirty, so we need to pay attention to the number of kilometers of the first insurance, half a year or 5000 kilometers to change the engine oil, to provide new lubricants for the engine. In short, when you get a new car, although you don't need to be careful, you can't do it casually, and you still have to take care of the vehicle.

The experience of some old drivers tells us that the new car should be treated gently for a period of time when it is just bought, because it is the sweet period (run-in period) with it at the beginning, and you can not violently drive on the accelerator and brake, nor can you run at high speed, which can extend the service life of the car. However, there is another theory circulating in the market now:

Today's automobile manufacturing technology is very advanced, and the machining accuracy of each part is much higher than before, so the new car no longer needs to be run-in, and you can drive it as you want.

But what I want to say is that there is no big problem with the above two statements, both of which are reasonable but not to the point. For the first statement, it is right that a new car cannot be driven violently, but it does not mean that it must be driven slowly to be correct.

The second way of saying is that the automobile manufacturing process is indeed very advanced, but no matter how advanced, the errors in the processing process of the parts still exist objectively, especially the gears and metal parts inside the engine and gearbox, and the surface will be slightly uneven or not tightly matched, so it will take a period of running-in to smooth and grind, so that the engine can reach the best working condition.

Therefore, the run-in period still exists, the correct run-in can make the service life of the car longer, the working condition is better, and the wrong run-in will hurt the car, so how to run in is right? Let's start with the most important component, the engine.

The engine is undoubtedly the core component of the car, with high technical content, complex design, and many parts, and there are naturally many places that need to be run-in. Careful friends will find that when the new car is bought and driven for a period of time to go to the first warranty, there will be a lot of metal chips in the engine oil, which is the uneven place on the metal surface of the parts, which is ground off during the run-in period. The engine oil when the new car leaves the factory is not very different from the oil we usually use, and the manufacturer will add a running-in agent to help the new car run in.

After understanding this, it is easy to understand why the new car should be run-in. In addition, running-in is a step-by-step process, just like sharpening a knife, you need to sharpen it slowly little by little, otherwise the knife may be sharpened. The engine and gearbox are the same, and it is not advisable to drive fiercely during the run-in period, otherwise the parts will "hurt each other", so that the life will naturally be shortened.

Therefore, before the first insurance, I recommend that you keep the engine speed not more than two-thirds of the red line speed. For example, if the red line speed is 7000, then do not exceed 4600, especially in the first 3 to 500 kilometers on the road. In addition, there are people who are entangled, how much should the maximum speed not exceed during the run-in period?

What I want to say is that it is better to look at the speedometer, as long as you do not drive over the speed limit (generally 110km h), drive well in accordance with the law, and accelerate sharply, the speed and speed will be within the safe range of the run-in period, and you don't have to deliberately control it. Because, at a speed of 110km/h, the speed of the family car will not be too high, which does not harm the engine or gearbox.

Now all cars have a run-in period, if the run-in period is too fast for the engine, it may cause irreparable damage to the engine-related components.

First of all, under normal circumstances, the left side of our dashboard shows the speed of our vehicle, are such numbers, when the pointer points to 2, its real speed is 1000 times this number, that is, 2000 rpm, when the new car is driving during the run-in period, it is recommended that you best not exceed 3, that is, do not exceed 3000 rpm, it is best to keep it at about 2000 rpm.

Because the parts of the new car engine do not achieve a good fit, we need to continue to run in, if the speed is too high, it may cause wear and tear of the parts, and the engine parts can not achieve a good fit.

The second is speed. Nowadays, more and more cars are using electronic instrument displays, instead of the previous analog type, so that the instrument panel can display more information.

Under normal circumstances, our speed will generally not exceed 100km h, and it will not exceed 120km h when running at high speed, because most roads now have speed measurements, we must be optimistic about what the maximum speed of the road is when driving, do not exceed this number, once speeding will not only face deducted points and fines, but also increase the danger of our driving.

However, during the run-in period, the car should pay more attention to maintaining speed, not speeding, and generally not exceeding 100km h. If it exceeds 100km h, it is a high-speed operation, which will have a certain impact on the service life of the engine and gearbox in the later stage.

But you don't have to worry too much, it's okay to drive fast occasionally, and now the cars are generally almost run-in before leaving the factory, and the so-called run-in period is actually the run-in tires.
