How to run in the new car on the road to be scientific?

First of all, the speed of the vehicle must be controlled below 80 kilometers per hour, because the tires and various parts of the transmission shaft need to be run-in.

Although the new car has been simply run-in when it leaves the factory, the speed control below 80 mph is also a kind of protection for the tires and brake discs.

Secondly, it is best not to exceed 2000 rpm. After the new car left the factory, the engine has not yet been run under high load, and the various drive rods are still in the running-in stage.

Therefore, the speed must be in the low-speed range to ensure that the various parts of the engine are fully run-in.

After the run-in period of a new car, you must remember to change the oil. During the break-in period of the engine, debris caused by friction between various parts will remain in the oil, so in order to prevent these debris from entering the combustion chamber, the oil must be changed.

It is better not to run at high speed in a new car. Many times the driver thinks that running at high speed can have a comprehensive test of the performance of the vehicle, but it is best not to go on the high speed during the run-in of the new car, because the speed of the high speed must exceed 80 miles, and the speed must be 2000 rpm, so it is definitely not suitable.

The main thing is to pay attention to the following three points.

1. Power system: control engine speed.

It is generally recommended that a new Hyundai car should run a full 2,000 kilometers after purchase before the run-in ends, which is the basic mileage to ensure that the parts are fully contacted, rubbed, adapted, and finalized. There are speed regulations in the initial driving stage of new cars, and most cars usually stipulate that 75% of the nominal maximum speed should not exceed the initial 1000 km to 2000 km, and it is required to pay attention to the engine tachometer and speedometer in use, so that the engine speed and vehicle speed are working at medium speed. In general, the engine speed during the break-in period should be limited to between 1500 and 4000 rpm.

However, whether it is the speed of the run-in period and the engine speed is not too harsh, the average driver as long as he runs in according to his normal habits There is no problem. It is important to note that most people are used to idling the engine and waiting for the water temperature to reach a normal temperature before driving away, especially for new cars. In fact, if modern EFI engines are preheated for a long time, it is not only unnecessary but also harmful.

Shortening the warm-up time can extend the service life of the three-way catalytic converter, and can also improve the conversion rate of pollutants in the exhaust gas and save fuel. The correct way is to start the car after the engine starts, the engine falls back to the normal idle speed to get up and walk, and the speed can be properly controlled before the water temperature rises.

2. Suspension system: avoid overload.

Running a new car at full load will cause an excessive burden on the suspension parts. Therefore, in the first 2000 kilometers, the load of the new car should not exceed 75% of the rated load, and in addition, the road surface should be of good quality as much as possible to avoid the load on the body and suspension caused by excessive bumps. New car owners often care about the run-in speed and ignore the requirements of limiting the load of the vehicle during the run-in period.

For example, the rated load of a car is 400 kg, and the run-in period cannot exceed 75% of the rated load, that is, 300 kg, as long as there are 4 middle-aged men in the car, it is likely to exceed this limit, but it is difficult for ordinary people to realize this. Therefore, during the run-in process of the new car, please try to reduce the burden on the suitcase, and for the request of friends to take a ride, you should also weigh their weight in advance.

3. Brake system: Do not brake urgently.

Emergency braking not only impacts the braking system in the running-in, but also increases the shock load of the chassis and engine, so try to brake in advance within the initial 2000 kilometers, and do not use emergency braking. But as far as the run-in of the brake system is concerned, it only needs to go through about 400 kilometers of driving. The run-in of brakes mainly includes the running-in of brake pads and brake discs, brake pads and brake hubs, etc., which can be completed after about 400 kilometers. ‍‍

Today's American article: Time can't go back to the place where it started--- for some things that have been missed, maybe you don't have to try to keep it, and if you are wrong, you will be wrong. We should all be grateful for what we have gained, and who can guarantee that what should have been yours for what we have lost?

There are some things that are meant to be cared for rather than acquired. The world has changed, unforgettable people, dreams, expectations, roads, and some that I think should be cherished, so what now?

Automobile running-in refers to the process of polishing the processing marks of parts and components to make them more encrypted. Now many people think that the vehicle does not need to be run-in, the reason is: the machining technology has made great progress, the engine cylinder honing is extremely smooth, and the use of laser honing, so the precision of modern technology has not required people to drive the vehicle to run-in.

When the author asked an old employee of an automobile factory, it made me re-acquaint myself with the run-in, and the old employee said this: of course, the car is to be run-in, even if the technical level is much higher than the original, but the current run-in method is not the method of more than ten years ago, it can be said that most people are driving every day in the run-in vehicle.

Volkswagen owner's manual: Volkswagen puts forward four requirements for running-in, 1The run-in mileage should be more than 1500 kilometers; 2.

The rotational speed shall not exceed 3 2 when running-in;3.For the first 600 kilometers, the grip of the new tires is not as good as it can be; 4.The friction of the new brake pads was not optimal for the first 200 km.

I want to cry, but I'm still laughing; I obviously care, but I pretend I don't care; is obviously very painful, but he says that he is very happy; I can't forget it, but I say I've forgotten it; Obviously very vulnerable, but pretending to be strong; Obviously said a lie against his will, but said that it was his true words; It's irretrievable, but it's still persistent; I knew that I would be harmed if I said such a thing, but I endured the pain and said it easily.

Do not drive over the speed limit, do not exceed 100 km/h on high speeds, and do not drive aggressively and do not allow long periods of overload when starting.

Do not exceed 3000 rpm! Do not exceed 80 km/h.

Different cars have different requirements, and run in according to the requirements of the manual.

1. The main thing to pay attention to when running in a new car is not to always exercise at one speed.

2. For the problem of the number of run-in kilometers, it varies from time to time, from car to car, I have heard two kinds of sayings, one is that under the modern technical conditions, the new car has passed the static run-in factory, and after the car is bought at home, it is necessary to pay a little attention to it when exercising, and there is no need to run in deliberately; Then there is the mainstream point of view, that the car mentioned home, until the end of the first guarantee, about 5000 kilometers, this section is the number of run-in kilometers, probably agree with the second point of view of the majority, after all, gears and other systems, all need a certain amount of lubrication and anastomosis connection.

3. The speed of running-in should not always run at a speed, and the speed of the car should not exceed 80. Since it is a run-in, it should be all in the city, and the city roads should not allow more than 80.

4. Non-special circumstances, you should choose the first insurance after pulling the high-speed, I personally recommend opening the sx4 pull the high-speed should grasp the principle, abide by the law, cherish life, 120 is enough, especially the sx4 4-speed automatic transmission, the first section to watch the news, there is a new car to pull the high-speed, the result of gameover. In the end, even the insurance company is exempt from liability.

There is no problem with automatic transmission in the end, generally speaking, the automatic transmission car takes a very steep downhill, rain, snow and mud road, you can choose to hang the corresponding L gear, under normal road conditions, the uphill and flat road is basically not necessary, because even if you hang 2 gears to run, it is not regarded as a car from 2 gears, but to control the movement between gears. Therefore, whether it is driving an automatic transmission car, or driving a manual automatic, there are almost few gear-shifting games, and they are all running the world in one d!

I don't know if my explanation can be understood!

The following aspects should be noted in the run-in of the new car:

Do not allow the machine to rotate too high.

During the run-in period, we all know that the speed can not be too fast, such as can not exceed the speed of 80 kilometers or 90 kilometers per hour, but one thing to note, the speed does not explain any problems, more important is the speed, as mentioned earlier, the run-in period is the process of engine smoothing and grinding, too high speed will damage the surface of the wheel axle, therefore, more attention should be paid to the speed than the speed, no matter how many gears, the speed generally should not exceed 3000 rpm, such as automatic transmission should not exceed 3500 rpm.

However, there are many cars with fifth or even sixth gear that is already high at 3000 rpm. It doesn't matter, the speed is just the embodiment of the power under a certain speed, so as long as the speed is not exceeded, it doesn't matter.

Do not allow the machine to rotate too low.

If the speed is too low, it will not achieve the running-in effect under normal use, and the speed should be kept between 2000 to 2500 rpm during driving.

Do not hold one gear for a long time.

Some friends in order to make the car fast past the run-in period, often hang five or four gears, in order to grind the car and grind the car, do not know that this will make the engine age rapidly, the surface is uneven under the premise, and it is a long time of physical work, the machine can not stand it (automatic transmission does not need to be considered).

It is best not to idle.

Don't let the machine be overloaded, generally use oil to give the car some force, and don't use first or second gear to idle.

Do not drive with weight.

During the run-in period, the lighter the car, the better, it is best not to pull five people to run around at once, and the weight of the machine will also be damaged. Don't pull heavy objects, such as pulling hundreds of pounds of rice.

Use daily use to run-in, and each gear must be grinded.

From first gear to fifth gear, you have to use one gear, so the best thing to do 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).

Don't prematurely take out the insurance, usually 2000 or 2500 and then go.

Some people like to maintain before the specified first insurance date, in fact, this is not good, a certain first insurance date is scientifically calculated, so it is not advisable to first protect in advance.

Don't drive for too long, let the machine have time to adjust.

Don't let it run all day long, like a taxi, you have to put it on for a few hours at most, let it rest, don't buy a new car and fresh, and practice, run all over the city on Saturdays and Sundays, but I don't know how much it hurts the car.

After grinding, the car is powerful and the gear is clear, and the few pieces of iron under your feet will be much lighter. Grinding is not good, driving will not have any feeling, but the kilometers up, small problems will come out, at this time you don't want to say that the car is not good, think about how to grind the car, grinding will also reduce the engine life, maybe 10,000 or 10,000 kilometers after your car will be boring, the machine may also have to be overhauled in advance, grinding the car is the foundation of driving, should be the top priority, please pay attention, not child's play.

Do you still need to run in on the new car you buy now? Is it okay to drive directly on the highway?
