Title: **Innovative Contributions of Satoru Okuma: A Pioneer in Engine Technology**
Introduction
Satoru Okuma is an esteemed inventor residing in Kanagawa, Japan. With a remarkable portfolio of four patents, Okuma has significantly contributed to advancements in internal combustion engine technology. His innovative designs aim to enhance engine efficiency and performance, making notable strides within the automotive industry.
Latest Patents
Among his latest patents is a groundbreaking multi-link piston-crank mechanism for internal combustion engines. This invention features a lower link formed in a manner where the outer circumferential sides of both end portions of a crankpin through-hole are designed to be stiffer than the center portion. The bifurcated shape of these portions ensures structural integrity during operation. Additionally, the center portion's inner circumferential surface is situated inward of the end portions and maintains a straight configuration in the axial direction of the crankshaft without load input, contributing to improved performance.
This innovative mechanism addresses the variable compression ratio of internal combustion engines. At low compression ratios, lubricating oil is ejected from the lower link oil passage and reflects off the upper link, supplying oil to the cylinder's inner wall. Conversely, at high compression ratios, the oil is directed to the backside of the piston crown, optimizing lubrication under varying operational conditions.
