Running-in refers to allowing the new car to walk for a period of time to allow all parts of the engine to run in smoothly. When a new car leaves the factory and starts to drive, since the moving parts of each part of the car have not run-in, it must be used with caution, otherwise the damage to the parts will be aggravated.Therefore, it is generally specified within a certain initial mileage, such as within 1500 to 2000 kilometerscarThe driving must be carried out strictly in accordance with the regulations. This period of time is called the running-in period of the car, or the running-in period. Of course, this is not to say that the car will inevitably be damaged if there is no fit. However, in order to maintain good performance of the car for a long time, it must be run-in. If the run-in can be performed correctly, the good feeling of driving can be greatly improved.
The running-in period of a car is like an athlete's warm-up exercise before the competition. The purpose is to adjust and improve the ability of various parts of the body to adapt to the environment. "A good start is half the success." The pros and cons of a car running-in will have an important impact on the life, safety and economy of the car, which should not be underestimated. Therefore, to do a good job in inspection and maintenance, to improve the quality of running-in, the following issues should be paid attention to.

In the use of the car during the running-in period, the following basic principles should be followed, which are the basic requirements for maintenance during the running-in period:
1. Load reduction: The load of the car during the running-in period cannot exceed 75% of the rated load. The new car should be loaded below the specified load or number of people, not to mention overloading, because overloading will aggravate the engine,transmission,Transmission system, Suspension system and other components, aggravate wear and tear, and cause damage to the vehicle.
2.Choose qualitylubricating oil: Choosing low-viscosity and high-quality lubricating oil can make the friction surface get good lubrication and slow down the wear of mechanical parts.
3. Reasonable use of fuel: Generally speaking, SE grade should be selected for gasoline engine, and gasoline of better quality should be added as much as possible (gasoline grade is not necessarily very high, but it must be clean). In addition, try to choose a better quality road surface to reduce the load on the body and power system.
4. Correctly adjust the ignition system and fuel supply system: Correctly adjust the ignition system and fuel supply system, which can solve the changes caused by the installation of the speed limiter and improve the economy of the running-in period.
Since the parts are still in the running-in period, excessive load and high speed will aggravate the impact on the parts. Not only will it not reduce the roughness, but it will also cause damage to the parts. If you step on the accelerator and accelerate quickly, it actually makes the engine work under a large instantaneous load. If the surface of the parts is not properly meshed, it is easy to wear due to impact. If you drive at a certain speed for a long time, you should also try to avoid high speeds and heavy loads.
