Latest Patents

Miyazaki's latest patents include the **Stratified Scavenging Two-Stroke Cycle Engine**. This groundbreaking engine design enhances leading air suction efficiency with a simple structure that remains cost-effective. The engine features an exhaust port and a scavenging port connected to a cylinder chamber, along with a leading air suction port not directly connected to the cylinder chamber. Additional components include an air-fuel mixture suction port, a scavenging flow passage, and a piston groove located at the outer edge of the piston. This innovative arrangement allows for efficient air intake, positioning the leading air suction port opposite the air-fuel mixture suction port relative to the cylinder axis.

Another important invention by Miyazaki is the **Air Cleaner for Engine**. This air cleaner design comprises openings along the circumference surrounding a suction chamber linked to a carburetor's suction port. Incorporated features include a filter that covers these openings, an internal suction path, partition walls that separate the suction path from the suction chamber, and a communicating path to manage airflow. This design helps to mitigate the sound produced by the engine's suction without compromising the air intake area.
