[汽车维修知识]Knowledge of car repair

When the driver finds that the vehicle is malfunctioning, he must go to the repair shop for maintenance. At this time, if you can’t accurately explain the situation, it will not only be detrimental to the thorough troubleshooting, but will also extend the troubleshooting time and bring unnecessary losses to yourself. For this reason, the author reminds the vehicle to be repaired to master the following two points:
1. Strengthen the understanding of vehicle technology.Some drivers report for repairs inaccurately, and the scope is large and wide. It is difficult for mechanics to make accurate judgments on faults, such as "engine failure", "chassis abnormal noise", etc., abnormal chassis noise may be caused bytransmission, There is a problem with the drive train or reducer, or the differential or suspension is faulty. The engine is weak or difficult to start. There are twenty to thirty causes, including the starting system, ignition system, fuel supply system and mechanical parts. Therefore, this requires the driver to have a comprehensive understanding of the technical status of the vehicle, so that when reporting for repairs, they can put forward their own views and provide them to the maintenance personnel, so as to shorten the repair time and improve the quality of the repair.
Second, troubleshoot timely and accurately.carDuring the driving process, as the mileage increases, each component will be abraded, deformed, damaged, and loosened, leading to failure. Generally, failures have symptoms before they appear.For example: the steering wheel is unstable and sometimes jitters (some drivers do not realize or think it is a small problem that is insignificant, but they do not know that this is the root cause of the failure.) If the necessary maintenance is not carried out, the steering ball may fall off orSteering knuckleThe breakdown of the arm will cause a bigger accident and cause serious losses. Therefore, if the fault is found, it should be reported for repair in time, so that the maintenance personnel can diagnose and eliminate the fault in time. The car can drive safely if it has no faults.
