When the fuel injection armature driven needle valve from its seat up about 0.1mm, the fuel spray from the precision gap. In order to make the fuel fully atomized, the front end of the needle valve grinds an injection needle. Injector suction and fall time is about 1 ~ 1.5ms.
Valve ball valve light weight, spring preload, get a broader dynamic flow range. Ball valve with automatic centering, good sealing. At the same time, the ball valve simplifies the structure of the metering section, helping to improve the fuel injection accuracy.
The combination of a light weight valve plate and ported seat with a magnetically optimized injector assembly allows the injector not only to have a large dynamic flow range but also to resist clogging.
The bottom of the oil supply, the fuel can be around the seat area through the injector cavity from the top of the continuous outflow of the metering unit of the fuel injector cooling effect is very obvious, it can effectively prevent air resistance and improve the car hot start The reliability.
In addition, the use of the bottom of the fuel injector can save the fuel manifold, and help to reduce costs.
