Title: Yasuhiro Furuhashi: Innovator in Fuel Injection Technology
Introduction
Yasuhiro Furuhashi is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of 3 patents. His innovative designs have improved the efficiency and functionality of fuel injection systems in internal combustion engines.
Latest Patents
One of his latest patents is a fuel injection timing apparatus. This apparatus features a pair of weights that rotate synchronously with the engine. The adjustment of the injection timing of a fuel injection pump is achieved through the movement of these weights against the biasing forces of springs. Additionally, it includes stopper members that move perpendicularly to the weights' movement and temperature-sensitive driving devices that adjust the stopper members based on ambient temperatures. This design ensures that the weights are restrained when the engine starts, enhancing performance.
Another significant invention is a device for adjusting the injection timing of a distribution-type fuel injection pump. This device allows for the adjusting piston to be moved in response to fuel pressure and the resilient force of a timer spring. It features an additional cylinder and a sliding shaft that enables easy adjustment of the piston position without requiring strict machining precision. This innovation simplifies the initial timing adjustment when mounting the fuel injection pump on the engine.
