Latest Patents

Okui's latest patents focus on innovative cooling structures for internal combustion engines. One of his patents describes a spacer that covers the intermediate portions of respective cylinder bores within a water jacket. This design allows the intermediate portion of each cylinder bore to reach higher temperatures, leading to thermal expansion. As a result, the clearance between the cylinder bore and the corresponding piston increases, reducing friction and improving fuel efficiency. Additionally, the temperature of the oil lubricating the intermediate portion rises, decreasing viscosity and further enhancing friction reduction. The cooling performance of the upper and lower portions of the cylinder bores is also secured, preventing overheating.

Another patent by Okui involves a spacer arranged inside a water jacket surrounding the cylinder bores. This spacer is designed with a lower height in the intermediate portion, which improves the cooling performance of the intermediate cylinder bores compared to the end-portion cylinder bores. This innovation ensures uniform temperatures across all cylinder bores, contributing to the overall efficiency of the engine.
