Latest Patents

Among Mizushima's latest innovations are two notable patents related to two-cycle engines. The first patent describes a two-cycle engine that features a cylinder block containing at least one pair of first and second cylinders, with corresponding exhaust ports. Each cylinder houses a piston that operates in reciprocal movement, cleverly controlling the exhaust ports' opening and closing during its cycle. The arrangement allows for a synchronized movement of two pistons out of phase, improving the engine's efficiency.

The second patent introduces an innovative design that includes an engine body with a single cylinder, an exhaust port, and a scavenge port positioned opposite the exhaust. The piston within the cylinder is designed to effectively manage the closure of these ports through its reciprocal movement. A unique aspect of this design is the integration of a transverse bore within the piston, allowing it to interact with both the exhaust and scavenge ports, further enhancing engine performance.
