Title: Hirofumi Mutoh: Innovator in Air-Fuel Ratio Control Systems
Introduction
Hirofumi Mutoh is a notable inventor based in Wako, Japan. He has made significant contributions to the field of internal combustion engines, particularly in air-fuel ratio control systems. With a total of 4 patents to his name, Mutoh's work has had a considerable impact on engine efficiency and performance.
Latest Patents
One of Mutoh's latest patents is an air-fuel ratio control system for internal combustion engines. This innovative system includes an air-fuel ratio sensor arranged in the exhaust system, which generates an output that is substantially proportional to the air-fuel ratio of exhaust gases emitted from the engine. The system detects variations in combustion and adjusts the desired air-fuel ratio accordingly. When the engine is in a predetermined operating condition, the desired air-fuel ratio is set to a leaner value than the stoichiometric air-fuel ratio based on the detected variation. Feedback control is implemented to maintain the desired air-fuel ratio, ensuring stable combustion.
Another patent by Mutoh focuses on feedback control of the air-fuel ratio of the mixture supplied to the engine. This system utilizes an ECU that responds to the output from the air-fuel ratio sensor. It adjusts the feedback control gain based on the influence of evaporative fuel purged from the fuel tank. This ensures optimal performance and efficiency of the engine.
