When the solenoid valve of the car is broken, it will cause the transmission to shift gears frustratingly, slip, enter the gear shock, and fail to upshift some problems. Many people who don't understand think that the turbocharger is broken, and it is also on the turbo.
If the valve controlled by the electromagnetic coil pulse is closed, the electromagnetic fuel injection valve, the idle speed control electromagnetic valve, the electromagnetic coil of the ignition device, and the automatic transmission electromagnetic valve will directly affect the fuel injection, ignition, idle speed, starting, etc. of the car. Work problems arise.
Automotive electromagnetic injectors are composed of a set of electromagnetic coils, armature switches, injection needles and valve seats. They are used frequently and for a long time. Occasionally, due to poor energization of the electromagnetic coil, the needle valve is stuck and no fuel is injected, resulting in poor or non-atomized gasoline atomization, which will hinder or stop the engine from working. If the car is found to be faulty after the running-in period, mainly check the use of fuel injectors and spark plugs. If the cold start is difficult, check the operation of the fuel injector and related connection circuits, because the fuel injector does not work well or does not work during cold start, which directly affects the start-up and refueling work. It will also lead to high fuel consumption, damage to the three-way catalytic converter and a series of problems such as carbon deposits, which will affect the service life of the car.
