Latest Patents

One of his latest patents is an air-fuel ratio controlling method and apparatus for an internal combustion engine. This invention involves a method and apparatus that selectively performs closed-loop and open-loop control based on the engine's operating conditions. The closed-loop control determines the air-fuel ratio of the mixture supplied to the combustion chamber by analyzing the oxygen concentration in the exhaust gas. Meanwhile, the open-loop control adjusts the air-fuel ratio determined in the closed-loop control to ensure it is leaner by a predetermined ratio. Another significant patent is an air flow rate measuring apparatus. This device features an air flow sensor whose electric characteristics change with the air flow rate. The sensor is mounted on a heat-insulating support member and is strategically placed in a bypass tube near the main venturi of the engine. This design minimizes thermal interference, thereby enhancing the accuracy of air flow rate measurements.
