Latest Patents

Kawahara holds a patent for a fuel injection system designed for internal combustion engines. This system features a vacuum-operated air-valve actuator that maintains communication with the intake air passage at strategic points. In low load engine operation, the actuator utilizes a relatively high vacuum from the downstream side of the throttle, along with a lower vacuum in the Venturi. This mechanism increases the air valve's opening, thereby reducing the vacuum in the Venturi and minimizing the density of unburnt ingredients in the engine exhaust gases. He has 1 patent to his name.
