Title: **Michiaki Uzihashi: Innovating Two-Cycle Internal Combustion Engines**

Introduction

Michiaki Uzihashi is a notable inventor based in Mishima, Japan, recognized for his contributions to the field of internal combustion engines. With a total of two patents to his name, Uzihashi has been instrumental in advancing automotive technology, particularly within his role at Toyota Motor Corporation.

Latest Patents

Uzihashi’s latest innovations focus on two-cycle internal combustion engines. His first patent describes a two-cycle internal combustion engine that features a cylinder head with both an intake port and an exhaust port, opening into a combustion chamber. This innovative design introduces compressed fresh air through an intake valve and includes an inclined concavity on the piston’s top face. In this system, the exhaust valve opens earlier than the intake valve during rapid piston descent, allowing part of the exhaust gas to flow back into the combustion chamber. This creates an exhaust gas swirl, which is effectively managed by the inclined concavity.

His second patent improves upon this design, introducing a cylinder head with an intake port and two exhaust ports. Here, the intake and exhaust valves are synchronized according to the crank angle, with one exhaust valve opening earlier than the others to facilitate the flow of exhaust gas back into the combustion chamber. This arrangement again fosters an exhaust gas swirl, further optimizing the combustion process.
