Title: Toyosei Yamauchi: Innovator in Combustion Chamber Technology
Introduction
Toyosei Yamauchi is a notable inventor based in Tachikawa, Japan. He has made significant contributions to the field of internal combustion engines, particularly in the design of combustion chamber structures. With a total of 2 patents to his name, Yamauchi's work focuses on enhancing engine efficiency and performance.
Latest Patents
Yamauchi's latest patents include innovative designs for combustion chambers that feature unique piston cavity structures. One of his patents describes an internal combustion engine with a pentroof-shaped combustion chamber. This design incorporates a piston with a cavity and a caldera-shaped protrusion around it. The configuration allows for fuel injection directed downward into the piston cavity, with a spark plug positioned obliquely near the intake valve. This arrangement promotes the formation of a locally rich air-fuel mixture around the spark plug, facilitating stratified charge combustion.
Another patent outlines a similar combustion chamber structure, where the piston features a circular protrusion. In this design, fuel is injected in a hollow cone shape, colliding with the piston cavity and diffusing effectively. The diffused fuel is carried by the tumble flow of intake air, gathering around the spark plug electrode, which contributes to stable stratified charge combustion. The circular protrusion also helps prevent fuel from scattering towards the cylinder wall.
