Now that the new semi-trailer is still in use, there is no need to run it in. What is the scientific adjustment? In response to this problem, experts from the Zhucheng trailer factory have something to say. First of all, we must emphasize that although the manufacturing precision of modern semi-trailers has reached a very high level, if we want to get the best working conditions for cars, the necessary adjustments are indispensable. Of course, many old drivers are too cumbersome to work with, and the operation is difficult. It is for old semi-trailers with extremely low manufacturing precision in the past. For modern semi-trailers, especially intermediate-level joint ventures or imported trailers, they can only seize the following three The key part of the targeted driving can be fine.
Power system: control engine speed modern new car is generally recommended to run after 2000 km to calculate the end of running, this is to ensure full access to the parts, friction, adaptation, stereotypes of the basic mileage. In general, the engine speed during the run-in period should be limited to between 1500 and 4000 rpm. However, both the running speed and the engine speed are not harsh during the running-in period. Generally, the driver will have no problem if he drives in accordance with his normal usage habits.
It is important to remind that, after hitting a car, most people are accustomed to allowing the engine to run idly and wait until the water temperature reaches normal temperature before driving away, especially for new cars. It is not only unnecessary and harmful for the EFI engine of its generation to adopt long-time preheating. Shortening the warm-up time can prolong the service life of the three-way catalytic converter. It can also increase the conversion of pollutants in the exhaust gas and save fuel.
The correct approach is to start the walker after the engine is started and the engine falls back to the normal idling speed. Before the water temperature rises, the speed can be properly controlled.
Suspension system: Avoid overloading The vehicle will be overloaded when it is fully loaded. Therefore, within the first 2,000 km, the load of the new car should not exceed 75% of the rated load. In addition, the quality of the road surface should be selected as much as possible to avoid the load caused by excessive bumps on the body and suspension. New car owners often care about the running-in speed and neglect the requirement of limiting the vehicle load during the run-in period. For example, if a car has a rated load of 400 kg, the running-in period must not exceed 75% of the rated load, that is, 300 kg. As long as four senior men ride on the car, it is likely to exceed this limit, but it is difficult for ordinary people to realize this. a little. Therefore, during the running-in process of the new car, please try to reduce the burden on the trunk. However, for the requirement of friends to ride on the wind, you should also weigh in advance about their weight.
Braking system: Avoid emergency braking The emergency braking not only impacts the braking system during running-in, but also increases the impact load of the chassis and the engine. Therefore, it is necessary to brake in advance within 2,000 km of the initial driving and do not use emergency braking. However, with regard to the running-in of the brake system, it only takes about 400 kilometers to drive. The break-in of the brakes mainly includes the brake pads and brake discs, brake pads and brake hubs running in, etc. It can be completed by driving about 400 kilometers.
In addition, experts recommend not using the "first away from the rear brake" approach to the brakes running.
Although doing so can relatively reduce the impact on the engine during braking, it may pose a danger, and once it is established, it becomes even worse.
At the end of the Luzhou trailer factory experts reminded that the new semi-trailer should always check the engine oil, coolant, battery electrolyte is sufficient during the running-in period, found that the lack of a certain must be promptly added. After reaching the factory-specified driving range, it is necessary to promptly go to the service station to carry out the first inspection and maintenance of the vehicle, change the oil, filter, etc., and fully check the chassis system. The completion of the first insurance means that the new semi-trailer has successfully passed through the running-in period and will be able to serve you better.
