Title: Junichi Kaku: Innovator in Fuel Injection Technology
Introduction
Junichi Kaku is a prominent inventor based in Iwata, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of 11 patents. His innovative designs focus on improving the efficiency and responsiveness of fuel injection systems.
Latest Patents
One of his latest patents is the Fuel Air Injector, which features four embodiments aimed at minimizing variations in fuel discharge due to pressure differences between the injector valve and its seat. This is achieved by incorporating a restricted orifice downstream of the fuel injection point, which dampens combustion chamber pressures. The injector valve is designed as a poppet valve with a specially configured stem that allows for smooth operation while maintaining flow. In two embodiments, fuel is delivered above the configured portion of the poppet valve, while in the other two, it is delivered below, enhancing responsiveness.
Another notable invention is the Fuel Injection System, which includes an injection device with a pumping chamber. This device utilizes an electrically operated mechanism that can rapidly increase localized fluid pressure without the need for reciprocating a piston. The system is equipped with a discharge port for fluid release and a circuit that provides an energizing voltage to the device, allowing for adjustments in various characteristics of the voltage.
