Injector is a precision device with very high processing accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. What are the specific categories?
   (1) Axle-needle electromagnetic injector
　　 When spraying fuel, the armature drives the needle valve to rise about 0.1mm from its seat surface, and the fuel is sprayed from the precision gap. In order to fully atomize the fuel, a section of the injection shaft needle is ground out at the front end of the needle valve. The suction and fall time of the injector is about 1 to 1.5ms.　　
   (2) Ball valve solenoid injector
　　 The valve needle of the ball valve is light in weight, and the spring preload is large, which can obtain a wider dynamic flow range. The ball valve has self-centering function and good sealing performance. At the same time, the ball valve simplifies the structure of the metering part, which helps to improve the accuracy of fuel injection.　　
   (3) The light-weight valve plate and hole-type valve seat of the plate valve electromagnetic injector are combined with the magnetically optimized injector assembly, so that the injector not only has a larger dynamic flow range, but also Strong anti-blocking ability.　　
   (4) The fuel injector that feeds in the lower part adopts the bottom fuel supply mode. Because the fuel can flow out from the upper part through the inner cavity of the injector around the valve seat area, the cooling effect on the metering part of the fuel injector is very obvious. , So it can effectively prevent the air resistance and improve the reliability of the car's hot start.
