Title: Michihiro Yamane: Innovator in Internal Combustion Engine Technology
Introduction
Michihiro Yamane is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of internal combustion engine technology, holding two patents that showcase his innovative approach to enhancing engine performance.
Latest Patents
One of his latest patents is the "Blowby Gas Circulating Apparatus for an Internal Combustion Engine." This apparatus is designed to circulate blowby gas to engine cylinders, featuring a cylinder head cover with a first wall that defines a first passage. The design includes a first flange that extends outwardly from the first wall, and a cylinder head with a second wall and a second flange that cooperate with the first flange to create an abutting surface. This configuration allows for efficient gas circulation between the first and second passages, ultimately improving engine efficiency.
Another significant patent by Yamane is the "Compression Ratio Control for Internal Combustion Engine." This invention addresses the operation of intake and exhaust valves in an internal combustion engine. At low speeds with low and medium loads, the intake valve closes at an advanced timing to enhance volumetric efficiency and increase the real compression ratio. Conversely, during low-speed operation with high loads, the exhaust valve closes at a retarded timing while the intake valve remains advanced, preventing knocking and maintaining engine performance.
Career Highlights
Yamane has worked with prominent companies in the automotive industry, including Nissan Motor Company Limited and Aichi Machine Industry Co., Ltd. His experience in these organizations has contributed to his expertise in engine technology and innovation.
