Title: Shigeru Sakurai: Innovator in Engine Technology
Introduction
Shigeru Sakurai is a notable inventor based in Hiroshima, Japan. He has made significant contributions to engine technology, holding a total of 9 patents. His innovative designs focus on enhancing engine performance and efficiency.
Latest Patents
One of his latest patents is the V-type two cycle supercharged engine. This engine features scavenging ports for its cylinders and includes a mechanical supercharger along with a surge tank. The design incorporates a pair of rotors arranged horizontally in parallel, with one rotor positioned directly below the other. The supercharger is offset laterally toward one of the banks from the center of the V-shaped space defined between the left and right banks. An air expulsion opening is strategically formed in the supercharger housing on the side nearest to the other bank. Additionally, the surge tank is located below the supercharger and is partly expanded upward on the side nearest the other bank.
Another significant patent is the intake system for diesel cycle engines. This system includes a timing valve positioned in the intake system during the engine's starting and warming-up period under cold conditions. The timing valve opens in the final period of the intake stroke, producing a strong suction pressure in the combustion chamber. When the timing valve opens, intake air rushes into the combustion chamber at high speed, compressing the air and increasing its temperature. The timing valve responds to the suction pressure in the combustion chamber, opening when the pressure exceeds a predetermined level.
