Title: Akira Takai: Innovator in Engine Technology
Introduction
Akira Takai is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of engine technology, holding a total of 3 patents. His work primarily focuses on enhancing engine performance and efficiency.
Latest Patents
One of his latest patents is for a supercharged engine. This engine features a geometric compression ratio of more than 8.5. The specifications establish a relationship where the intake port closing timing, expressed by a crank angle after the piston reaches BDC, and the overlapping angle, expressed by a crank angle for the overlapping time period during which both the intake and exhaust valves are open, are defined by the equation Y ≥ -1.75X + 10.
Another significant patent is for an engine air-fuel ratio control system. This system includes an air-fuel ratio detector that measures the concentration of oxygen in the engine exhaust gas. It provides a signal representing the air-fuel ratio of the engine intake mixture. A control unit compares this signal with a reference signal representing a desired air-fuel ratio. It adjusts the air-fuel ratio by a predetermined control factor, ensuring that the actual air-fuel ratio aligns closely with the desired ratio. The control factor is smaller when the desired air-fuel ratio is relatively lean compared to when it is relatively rich.
