Cases of Repairing Auto Parts

Introduction of Vehicle Failure

Vehicle in use process of failure is normal, so the driver cannot avoid dealing and repair plant. But the two sides will often around the quality of parts, repair rate repair, quality and price, have some conflicts. Therefore, it is very important to distinguish between right and wrong.

The Case of Repairing Trunk Release Solenoid

Some owners have a 17 passenger car, engine is a turbocharged. Already travel about three hundred thousand kilometers, which in the about two hundred thousand km at once overhaul. Some time ago because of burning oil and repair once, subsequent engine working normally and travel ten thousand kilometers. In a running for, the driver feel the loss of engine power and abnormal noise, continue to run, the deterioration of the situation until the engine stops. For the reasons of the roof caused by laser cladding, car repair factory accessories that have quality problems, repair quality does not pass. While the repair shop that the trunk release solenoid after the overhaul has traveled over ten thousand kilometers, and the used car accessories are authentic original, there is no quality parts and repair quality problems. Repair of the vehicle carried out a detailed diagnostic analysis, excluding parts quality and repair quality to melt top trouble, give both parties a claim. After the owner, also no longer find repair plant. Then, the fault diagnosis is how?

The Fault of Remote Trunk Release

First, carefully examine oneself melt top cars piston. The cylinder of the cylinder has been strained, piston ring and piston ring groove sticking together. By observing that, cylinder and piston and piston ring groove strain of adhesions is due to piston top melting caused by. Excluded from the mechanical part improper assembly by friction heat and causing the car to the piston top possibilities through examination of fusion, and ruled out by engine caused by over high temperature melt top factors. To provide manufacturers of accessories after detailed understanding. Through comprehensive analysis, concluded that failure occurs in a vehicle fuel system of fuel injector. As a result of remote trunk release mounted diesel engine, therefore, the work of the fuel injector condition quality, directly affects the working condition of the engine. Therefore, not only requests the injector can take certain pressure diesel fuel injected into the cylinder, but also in the jet when accurate timing, uniform distribution, good atomization. If not to spray to atomization and timing, appear even by automotive fuel injector seal failure caused by fuel leakage, so that the fuel in the cylinder will be gathered in one part of the continuous burning.
