Latest Patents
Naotake Ohi holds a patent for a fuel injection system that features a solenoid valve unit strategically placed in the fuel supply path leading to the compression space of an injection pump main body. This system allows for precise adjustment of the fuel injection quantity through the open and close control of the solenoid valve unit. During the preliminary injection phase, the plug valve is moved to seat on the valve seat, ensuring optimal fuel delivery. The design includes an arrangement for leaking fuel from the compression space, which stabilizes the movement of the plug valve and achieves a nearly constant small quantity for preliminary injection, regardless of engine rotation speed. This innovation enhances the stability of injection characteristics from pilot injection through to main injection.
