The acceleration performance of the car during the run in period is not to be at its best

It's a pleasure to buy a new car, and no matter what it's used for, we basically want it to be comfortable to drive and durable. While most car owners will want to get a new car in about 2-3 or 4-5 years, almost everyone wants the car to last as long as possible. In order to make your car live a long life, you should pay attention to maintenance from the beginning of the new car, especially during the run-in period, which has a long-term impact on the vehicle.

Many car owners are worried that the new car will run too fast, the engine will wear out abnormally, so they dare not step on the accelerator during the run-in period of the new car, so that in the long-term slow driving, the engine often keeps running at low rpm, but it is easy to cause carbon deposition inside the cylinder, so that the acceleration performance of the car is reduced. In addition, the new electronic jet engine control systems, such as the Buick, Opel, Saturn, etc., have an artificial intelligence transmission system that learns driving habits, and if you drive at a slow speed for a long time, the computer will adapt to this driving habit to slow down the response speed of the engine rpm increase. If you want to improve this situation after the run-in period, you can simply change your driving habits and let the computer shift system re-learn.

Basically, all vehicles are tested before leaving the factory, and they are also tested at high speeds to ensure that the new car can withstand the high-speed operation of the engine. However, during the run-in period, it is still necessary to keep the engine speed at about 3000 km as much as possible, not to exceed 3000 rpm, but in case of emergency, it is still necessary to go down with a big foot on the accelerator, and do not dare to step on the accelerator. And after 3000 km, the revs should be gradually increased so that the engine gradually exerts its performance.

At the same time, automatic transmission vehicles should avoid forced downshifts kick down, and manual transmission vehicles should not switch into low-speed files at high driving speeds to avoid engine overrotation. As for the engine lubrication oil, it can be replaced after about 3 months or 5000km, because some car manufacturers add special running-in oil to the engine of new vehicles, unless there are special circumstances, it is just a waste of money to replace it too early.

In addition, during the run-in of the new car, try to minimize the emergency braking, because at this time the brake disc hub and the brake order are also running-in, when the initial shape of its appearance has not been worn into the same, the frequent emergency braking will cause uneven wear, which is also one of the reasons why the new car has just started, and the braking is one of the reasons.

Not only the engine and brakes need to be run-in, but also many components such as bearings and other rotating components must be run-in, and making the driving as smooth as possible is the basic essentials of good running-in. In order to make a car have a long life, a good run-in period is only the beginning of success, in accordance with the original operation manual and maintenance specifications of the correct operation and regular maintenance, and remember to check 5 oil and 3 water frequently, in order to keep the vehicle in the best condition at any time.

The additive attributes of the run-in period determine the quality of the car.

If the new car does not perform at its best, the run-in will not be successful.

During the run-in period, the maximum speed of the new car is 100km/h.

The run-in period of a new car is generally divided into three stages: the initial period is 0-500km, the speed is maintained at 60-70km/h, and the speed should not exceed 2200 rpm; In the middle stage, it is 500-1000km, and it can be accelerated to 90-100kmh, and the speed is kept below 2500km; In the later stage, it is 1000-2000km, and the speed can be increased to less than 120km/h, and the speed should not exceed 3000 rpm.

During the run-in period, it is necessary to take it step by step, control the speed and rev of the car, do not drive violently, do not step on the accelerator, and do not brake sharply and slam the direction. Maintain the rpm and try to maintain the rpm while driving, it is not recommended to drive at high rpm.

Why should the new car be run-in

The reason why the new car needs to be run-in is because when the new car leaves the factory, the processing accuracy of the parts is not enough or there are errors in the assembly process, etc., and a certain mileage is needed to run in naturally, so that the ability of each part of the body to adapt to the environment can be adjusted and improved.

One of the most important is the run-in between the engine and the gearbox, which needs to be properly run-in in the first 2000 kilometers, which can play a very important role in the performance of the car and prolong the service life. But you don't need to deliberately run in, you just need to drive with good driving habits.

In today's new cars, the concept of running in is not as important as before. Because the production technology has improved, the precision has also improved, and the importance of running-in has decreased.

The run-in is still needed, but it is not as long as it used to be. In the past, 3000-5000 km is now 1000-1500 km is enough. Even many high-end cars no longer need to be deliberately run-in.

Running-in is two-fold.

One is the run-in of the engine. Because there are many models, it is difficult to accurately limit the speed of the vehicle. Now it is common to use engine speed limiting.

Generally speaking, for a new car, within 1000 km, the engine speed cannot exceed 3000 rpm. to protect the engine. Remember that the speed of each gear should not be exceeded.

The second is the run-in of the whole vehicle. Running-in of all the moving parts of the vehicle. Like wheels, brakes, gearbox, etc. The run-in of the engine is actually only one of the most important parts of the run-in of the whole vehicle.

But how to run in? You need to walk around in all kinds of road conditions. It's okay to take the highway, and it's better to take the national highway.

Walking for a while, stopping and waiting for a red light, and so on, are all running in on the various moving parts of the car. Remember not to press the brakes too hard, of course, in an emergency, you can press as you want. Run-in, for now, there is no difference from driving in normal times, and it is very rare for you to drive in times when the engine speed exceeds 3000.

After the run-in period, you decide when to change the oil (you can change it first, pull it first, pull it again), and pull it on the highway. Step on the throttle as much as you can, pull the revs up, and hold it for a while. Pull every gear.

This has a certain amount of fines, risks and dangers. It is possible not to pull the high speed. Because you can't use a car in your life to catch up with the limit driving a few times.

If you don't have the guts or don't think it's necessary, forget it. If you pull it, the car will run a little more smoothly, and it is estimated that ordinary people will not feel much difference.

Okay, that's all for the rest of it, I'm in the automotive world, and you can continue to ask me questions if you have relevant questions.

Do not exceed 100 kilometers before 2000 kilometers, do not accelerate sharply, that is, do not add cold oil.

Do not exceed 3000 kilometers at a speed of 80. After that, you have to run at high speed, run as fast as you can, so that the car will have strength in the future.

The car run-in period is not only the run-in between you and your car, but also the run-in between the various contact friction parts of the vehicle. Due to the progress of modern automobile manufacturing technology, the run-in process of new cars is also greatly shortened, and you only need to run 1000 kilometers "carefully", and your car can be fully fired.

So in the more than 1,000 kilometers before the new car is running-in, how to drive to extend the life of your car?

1.Do not brake suddenly:

Emergency braking not only impacts the braking system during the break-in, but also increases the shock load on the chassis and engine. Therefore, Xiaohuniu suggests that it is best not to brake urgently within 300 kilometers of the initial drive.

2.Do not overload:

If the new car starts to run at full load during the run-in period, it will cause damage to the parts. Therefore, within the first 1000 kilometers, the general load capacity should not exceed 75%-80% of the rated load.

3.Try to run as little as possible:

If the new car starts to run long distances during the run-in period, the continuous working time of the engine will increase, which is easy to cause wear and tear of the parts.

4.Don't drive at high speed:

Novices take a new car on the road, be sure to ask for stability, don't drag race with old drivers! In fact, this is because there is also a speed limit during the run-in period of the new car, and the domestic car is generally within 40-70 kilometers per hour, and the imported car is generally within 100 kilometers per hour. When the throttle is fully open, the speed of the vehicle should not exceed 80% of the top speed, and pay attention to the engine tachometer and speedometer while driving to ensure that it works at medium speed.

Under normal circumstances, the engine speed should be 2000-4000 rpm during the run-in period. If you think these numbers are too difficult to remember, then you can safely open 60 yards, and it will definitely be no problem

Speed limit during the run-in period of the new car. Generally speaking, domestic cars are within 40 to 70 km/h, and imported cars are generally within 100km/h. Ensure that the engine speed and vehicle speed work at medium speed, in general, the engine speed should be 2000 4000 rpm during the run-in period; Do not run long distances, the car runs long distances during the run-in period, and the continuous working time of the engine will increase, which is easy to cause wear and tear of parts.

In addition, you should change gears in time when driving to avoid driving at low rpm in high gear and high rpm in low gear. Generally speaking, the speed of each gear is controlled in the range of top speed 3 4; During the run-in period, the car should also pay attention to not doing emergency braking as much as possible, and strive to start slowly and stop slowly.

There are other things to note.

First: Avoid overloading.

The loading capacity of the car during the run-in period cannot exceed 75% of the rated load. When loading, the new car should be lower than the specified load capacity and number of people, let alone overloaded. Overloading can burden the engine, transmission, drivetrain, suspension and other components and accelerate wear and tear.

Generally speaking, domestic cars cannot exceed 75% of the rated load, and imported cars cannot exceed 90% of the rated load. In addition, in order to reduce the load on the body and power system, a relatively flat road surface should be selected to avoid vibration, collision or emergency braking.

Second: use high-quality gasoline.

The gasoline used in the run-in period of the new car should not be lower than the grade specified by the manufacturer, and the anti-wear oleaceum should not be added, so as not to have enough mileage and insufficient run-in. In addition, by correctly adjusting the ignition system and the oil supply system, it is possible to solve the changes caused by the vacuum economizer caused by the installation of speed limiting plates, and improve the economy of the running-in period. In addition, proper driving also includes gently lifting the clutch and accelerator pedal when starting.

After starting, it should run at low speed, preheat up to 50 60 and so on.

"1.Do not let the machine speed too high, during the run-in, we all know that the speed can not be too fast, such as: can not exceed 80 or 90 and the like, but one thing to note, speed does not explain any problems, more important is the speed, as mentioned earlier, the run-in period is the engine in the grinding and grinding process, too high speed will damage the surface of the uneven axle, therefore, more attention should be paid to the speed than the speed, no matter how many gears, the speed should generally not exceed 3000 rpm, If the automatic gear should not exceed 3500 rpm (slow work).

Conditionally, it is recommended to install the engine protection Shenhuixing MC Magnetic Blaster, and the run-in will be better.

2.Do not let the speed of the machine be too low, too low rotation can not achieve the running-in effect of normal use, and at least keep the speed between 2000 to 2500 rpm during driving.

3.Can not maintain a gear for a long time, some friends in order to make the car faster than the run-in, long hang five or four gears, in order to grind the car and grind the car, they do not know that this will make the engine age quickly, the surface is uneven under the premise, but also a long time of physical work, the machine can not stand (automatic transmission does not need to be considered).

4.It is best not to drive at speed, do not let the machine be too heavy, generally use oil to give the car some force, do not use the first or second gear to drive at speed.

5.The car should not be driven with weight, the lighter the car during the run-in period, the better, it is best not to pull five people running around at once, the machine will also be damaged if the load is too large, and do not pull heavy objects. For example, pulling hundreds of catties of rice and the like.

6.With daily use to run-in, all gears have to be grinded, from first to fifth gear, all have to be used, so the best way is to drive in the city, starting and stopping from time to time, which is also good for the machine (in other words, running in all kinds of road conditions). "

Due to the slight unevenness on the surface of the engine parts of the new car, the resistance will be relatively large, which will improve after running-in. However, this difference in drag is very small, as long as there are one or two other external factors, such as: insufficient tire gas, more and less engine oil, more gasoline and more weight, etc., will make this difference insignificant.

In addition, the speed of the run-in period is usually slower, and the driving state after the run-in is not very comparable, so the landlord does not need to care about the difference in power, if the power is much worse, it must be something else.

Hello, if the run-in period is smooth, the fuel consumption and power will be enhanced.

No, there are few problems after the run-in of the engine.

Hello car owners, the power of the new car will be improved to a certain extent after the run-in period, but you must develop good driving habits during the run-in period! Try to keep driving at a constant speed, try not to accelerate sharply, brake suddenly, I hope it can help you, I wish you a happy life! [If you have a problem with the car, ask the car master.]
