[0002] The injector pressure plate is an important component in the engine. It can be fixed to the engine cylinder head by bolts to limit the position of the injector in the engine and prevent the injector from shaking when the engine is running, which would affect the normal operation of the injector.
[0003] The fuel injector is a precision device with very high processing accuracy. It is required to have a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The fuel injector receives the injection pulse signal sent by the ECU and accurately controls the fuel injection amount. The spray characteristics of the fuel injector include atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle, etc. When installing the fuel injector on the engine, it is necessary to use a pressure plate component to achieve rapid positioning.
