If the engine is compared to the heart of your car, then the fuel system is the artery of your car. When heavy metals and other deposits accumulate and block blood circulation, it will inevitably affect your health! The most critical precision component in the "artery" (oil system) of your car is the fuel injector.
What is a fuel injector for a car?
The fuel injector is a simple solenoid valve. When the solenoid coil is energized, suction is generated, the needle valve is sucked up, the spray hole is opened, and the fuel is sprayed out at high speed through the annular gap between the needle pin at the head of the needle valve and the spray hole to form a mist. The better the atomization effect, the more conducive to full combustion. Simply put, it is a component in the engine fuel injection system, which is used to spray gasoline into the cylinder, mix with air and burn to generate power. The main function of the fuel injector is to control the time and amount of fuel injection to ensure that the engine can operate normally.
Common Failures and Causes of Fuel Injectors
1. Fuel injector blockage
Because impurities and water in the fuel will be deposited in the spray hole of the fuel injector, the fuel injector will be blocked. Blockage can cause problems such as engine shaking, weak acceleration, and increased fuel consumption.
2. Injector leakage
Poor sealing of the injector control valve or excessive pressure of the injector driver can cause the injector to leak. Oil leakage
Can cause problems such as reduced engine power and increased fuel consumption.
3. Damage to the injector solenoid valve
The injector solenoid valve is a key component that controls the operation of the injector. If the solenoid valve is damaged, it will cause the injector to fail to work properly, thereby affecting engine performance.
How to maintain and maintain the injector
1. Injector cleaningIt is recommended to clean the injector regularly, with an interval of 4-6w kilometers. You can use a special cleaner or fuel bottle to clean the injector.
2. Check the sealing of the injector and the pressure of the driver
Regularly check the sealing of the injector control valve and the pressure of the injector driver. If abnormalities are found, repair or replace parts in time.
3. Use high-quality fuel
Using high-quality fuel can reduce the impact of impurities and moisture on the injector, thereby extending the service life of the injector.
4. Avoid driving at low speed for a long time
Long-term low-speed driving will cause the fuel injector to be blocked, so it is recommended to drive at high speed appropriately to keep the fuel injector working normally.
