The fuel injector is one of the key components of the automobile engine and plays a key role in the performance of the engine. The fuel injector used in automobiles is actually a simple solenoid valve. When the electromagnetic 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, forming a mist that is conducive to full combustion. The engine fuel injector valve plate is an important component installed in the automobile engine. During the production process, the cleanliness requirements of the valve plate are very high. When cleaning, it is necessary to clean it with hydrocarbon cleaning fluid in a vacuum cleaning machine. The fuel injector valve plate is required to be cleaned 360 degrees in the vacuum cleaning machine basket, and the fuel injector valve plate has very high precision requirements and cannot be damaged during cleaning. The existing fuel injector valve plate cleaning device has low cleaning efficiency and poor cleaning effect, which can easily cause damage to the fuel injector valve plate.
