Title: Michiyoshi Yamane: Innovator in Carburetor Technology
Introduction
Michiyoshi Yamane is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of carburetor technology, holding a total of 4 patents. His work focuses on improving air-fuel mixture control systems for internal combustion engines.
Latest Patents
Yamane's latest patents include innovative methods for controlling air supply in carbureted engines. One of his patents describes a closed-loop air-fuel mixture control system that utilizes an exhaust gas sensor to provide feedback to a control unit. This system modifies the feedback signal to meet the control characteristics of the closed loop. The modified signal is then converted into digital pulses, allowing for both coarse and fine control of the air-fuel ratio. This innovation eliminates the need for calibration, accommodating the time-varying characteristics of individual carburetors.
Another significant patent involves a closed-loop fuel control system that detects various engine operational conditions. This system utilizes a mode detector to identify states such as idling, steady, and accelerating. It selectively actuates integrators with predetermined time constants, integrating output signals from a P-I controller. The integrated signals are stored in capacitors, which control electromagnetic valves in the carburetor, enhancing the efficiency of fuel delivery.
