The car run in period is fast, and how to run in the new car during the run in period is better

The run-in period of the new car is more reasonable according to the mileage regulations. The calculation of mileage should be based on the running-in situation of auto parts, generally starting from the new car, and the mileage required to run in the appropriate run-in of each part is the run-in period mileage. According to the measurement, the domestic car will pass 1500km of the run-in period mileage, the amount of cylinder wear and tear of other parts has basically reached the appropriate degree of combination, therefore, 1500 km is determined as the maximum mileage of the run-in period.

Of course, different types and brands of vehicles, the run-in process must be different, and the provisions on the run-in period mileage are not the same. Car owners should be mindful of these regulations and use their vehicles in strict accordance with them. The most important thing for the maximum speed limit car is to limit the engine speed during the run-in period.

In the run-in, the engine speed is too high will increase the possibility of damaging the piston ring, so the general manufacturer will recommend that the new car speed limit is 80 90km h in the speed section of 80 90kmh, whether it is a manual transmission car or an automatic transmission car, according to the normal shift requirements into an automatic speed switching point, the engine speed in this speed section is about 2500r min, and the maximum will not exceed 3000r min This is the key and essence of the speed limit: speed limit, In fact, it is limiting the speed of the engine! "Do not artificially increase the speed of the engine during the break-in period".

Generally speaking, the run-in period is divided into three stages: the early stage, the middle stage and the late stage, the initial stage, the maximum speed is generally controlled at about 40km h; In the medium term, the maximum speed can be increased to 60 km h in good road conditions; In the later stage, it can be increased to about 80 km h. During the run-in period, you can keep driving at a medium speed, and the speed can not be too high or too low, and the speed is too low to increase fuel consumption.

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 does 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 2500 rpm; 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 whole run-in period, you need 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.

Precautions for new car running-in.

Be careful not to change the oil too early: the initial oil of the car is a special lubricating oil for the run-in period, which requires low viscosity, good heat dissipation, superior cleaning and oxidation resistance, and some car factories have also added abrasives that are conducive to running-in, so the oil during the run-in period only needs to be changed according to the time specified by the manufacturer, and should not be replaced too early.

Be careful not to start without heating up the car: the new car must be warmed up before starting, the so-called preheating is actually to give the engine a full lubrication time, especially turbocharged models, must be warmed up before starting, and the lubrication time should be at least one minute or more.

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.

1. Preheat before starting. Before the EFI truck starts, you should turn the key to the second gear and wait for 5 to 10 seconds before starting. After the key door is opened, the gasoline pump is turned on to adjust the oil pressure and fuel injection volume, so it is good for the motor and engine of the car to start it after a few seconds.

In fact, this method of preheating is very wrong, because the EFI engine is not like the carburetor engine, before reaching the working temperature, the fuel supply system can not work normally, and the phenomenon of unstable speed and stalling will naturally occur when driving reluctantly, so the carburetor engine is a last resort. However, if the EFI engine is 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.

2. Don't drive at high speeds. There are speed regulations in the initial stage of new cars, and domestic cars are generally stipulated within 40-70 kilometers per hour; Imported cars are generally stipulated in the initial 1000 kilometers, when the throttle is fully open, the speed does not exceed the maximum speed of 80, and it is required to pay attention to the engine tachometer and speedometer in use, so that the engine speed and speed are working at medium speed. Generally speaking, the engine speed during the break-in period should be strictly specified between 2000 and 4000 rpm.

3. Avoid overload. Running a new car at full load will cause damage to the parts. Therefore, in the first 1000 km, domestic cars can not exceed 75 -80 of the rated load; Imported cars cannot exceed 90 percent of the rated load.

In addition, try to choose a better quality road surface to avoid excessive vibration, collision or emergency braking, and reduce the load on the body and power system.

4. Do not remove the speed limiter in advance. The speed limiter is a throttling device installed between the carburetor and the intake pipe. The driver should not remove it in advance, but after the initial 1000 kilometers in conjunction with the initial driving maintenance.

Imported cars generally do not add speed limiters, and the driver completely controls the speed by himself.

5. Do not run long distances. The long distance of the new car will increase the continuous working time of the engine, resulting in increased wear and tear of the parts.

Don't run in too strictly according to the instructions, control the speed to 2500 rpm before 5000 km, and change the oil once at 2000 km! Then go to 5000 high-speed running-in, the fastest speed on the manual is 30 minutes to 50 minutes high-speed running-in! My car has been running in like this, and it has been 4 years without any problem and the speed has just increased.

Because the new car may have deviations in the installation process and its parts are likely to have insufficient processing accuracy, etc., it is necessary to run in a certain mileage, which can bring great effect to the full play of the characteristics of the car and increase the service life. The run-in period of the whole vehicle is generally around 2000 kilometers, which is divided into new tire running-in, automobile engine running-in and gearbox running-in. Among them, the most important is the run-in between the engine and the gearbox.

The car run-in period is generally divided into three links:

Early stage (new tire running-in): 0-500km, the run-in between the tire and the floor, the speed does not have to exceed 2200 rpm;

Middle and late stage (automobile engine running-in): 500-1000km, the key includes the piston rod and cylinder liner middle, crankshaft and axle liner middle of these running-in, the speed is maintained at 60-70km h, can be accelerated to 90-100km h, and the speed is maintained below 2500 rpm;

Middle and late stage (gearbox running-in): 1000-2000km, the speed can be increased to below 120 kilometers with the run-in between the transmission gears of the box, and the speed does not have to exceed 3000 rpm.

During the whole run-in period of the car, it is necessary to go from shallow to deep, control the speed and speed, do not drive vigorously and safely, do not need to give oil violently, and do not need to brake sharply and hit the azimuth. The fuel consumption of the general run-in period is relatively very high, 1-two oil higher than the normal condition, which is specifically due to the fact that the middle of the new automobile components have not yet reached the best operating state, and is not very smooth, the friction is very large, and the driving lead is very laborious, so the relative fuel consumption is relatively relatively high. However, after the break-in period, the fuel consumption will be reduced to a certain extent.

Special attention must be paid to the fact that during the run-in period of the new car, the average speed should be maintained as much as possible and overload should be prevented. For manual transmission cars, it is necessary to immediately and moderately carry out gear shifting to prevent high-speed and low-speed operation at low gear, and do not have to drive in the same gear for a long time, so that the run-in between the car engine and gearbox is more sufficient.

For the selection and replacement of engine oil, it is recommended to refer to the car guide.
