Injector Classification

(1) Pin-type electromagnetic injector

When fuel is injected, the armature drives the needle valve to rise about 0.1mm from its seat surface, and the fuel is sprayed out from the precision gap. In order to fully atomize the fuel, a section of fuel injection shaft needle is ground at the front end of the needle valve. The suction and fall time of the injector is about 1-1.5ms.

(2) Ball valve electromagnetic 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) Disc valve electromagnetic injector

The combination of lightweight valve plate and orifice valve seat and magnetically optimized fuel injector assembly makes the fuel injector not only have a large dynamic flow range, but also have strong anti-clogging ability.

(4) Fuel injector with oil inlet from the lower part

The bottom fuel supply method is adopted, since the fuel can flow out continuously from the upper part through the inner cavity of the fuel 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 generation of air resistance and improve the reliability of the hot start of the car.

In addition, injectors that use bottom injection can save fuel rails and help reduce costs.
