Latest Patents

Yasuo Moriyoshi holds a patent for a two-stroke engine. In this design, fresh air is introduced through a scavenging port into a combustion chamber, creating an airflow directed to the top surface of a piston. This airflow is guided by a concave shape on the piston top surface, producing a reverse tumble flow. The combustion gas is expelled through an exhaust port, which is opened and closed by the piston, in a stratified state due to the scavenging flow. Additionally, when the exhaust port closes, a strong tumble flow occurs in the combustion chamber. At the ignition point near the top dead center, the reverse tumble flow interacts with a squish developing between the piston top surface and the lower surface of the cylinder head, gathering in the concave in a disturbed state.
