1.Turbocharger

The turbocharger increases the intake air volume by compressing air. It uses the exhaust inertial impulse of the engine to push the turbine in the turbine chamber. The engine speed increases, the exhaust gas exhaust speed and the turbine speed also increase synchronously, the turbine drives the impeller to compress more air into the cylinder, and the pressure and density of the air can increase. Burn more fuel to increase the output power of the engine.

Because the supercharger is often operated at high temperature, its lubricating oil pipeline is subject to high temperature, and the internal engine oil is likely to have some coking, which will cause insufficient lubrication of the supercharger bearing and damage. Therefore, the lubricating oil pipeline should be cleaned after running for a period of time, and turbochargers should be regularly repaired and pay attention to the correct operation method.

2.Electrical junction box Assy

The automobile electrical junction box assembly is the central unit of vehicle power distribution and signal transmission. It integrates relays, fuses, and some electronic modules to achieve the distribution of power and control signals for vehicle electrical equipment and to each electrical equipment. And wire harness for overload or short circuit protection. It plays an extremely special and important role in car driving.

The malfunctions mainly include: ablation or melting of the fuse, reverse connection of the relay coil, etc. Once a similar fault occurs, the vehicle will not work properly and drive, which shows that the reliable connection of the electrical junction box is essential, replace the fuse or relay, etc. must be standardize operations.
