(1) Axial needle electromagnetic injector
When the fuel is injected, the armature drives the needle valve to rise about 0.1mm from its seat surface, and the fuel is sprayed from the precise 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 to 1.5ms.
(2) Ball valve solenoid injector
The ball valve has a light weight of the valve needle and a large spring preload, which can obtain a wider dynamic flow range. The ball valve has automatic 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) Piece valve solenoid injector
The combination of the lightweight valve plate and orifice valve seat with the magnetically optimized injector assembly gives the injector not only a large dynamic flow range, but also a strong resistance to clogging.
(4) Injector with lower oil inlet
The bottom oil supply method is adopted, since the fuel can flow out from the upper part continuously around the valve seat area through the inner cavity of the injector, the cooling effect on the metering part of the injector is very obvious, so it can effectively prevent the occurrence of air resistance and improve the hot start of the car. reliability.
In addition, the use of bottom-injected injectors eliminates the need for a fuel manifold and helps reduce costs.
