Title: Koichiro Takeuchi: Innovator in Engine Intake Systems
Introduction
Koichiro Takeuchi is a notable inventor based in Iwata, Japan, recognized for his contributions to engine intake systems. With a total of 2 patents, Takeuchi has made significant advancements in improving the efficiency of internal combustion engines.
Latest Patents
Takeuchi's latest patents include innovative designs for engine intake systems. The first patent focuses on several embodiments of engine intake systems that enhance charging efficiency. This is achieved by providing a closed branch passage that forms a volume in the intake tract between the throttle valve and the discharge point into the engine chamber. The designs cater to both four and two-cycle engines. Additionally, a plenum chamber is illustrated to increase the effective volume of the branch passage without significantly extending its length. Certain embodiments are oriented to increase turbulence during the intake cycle, thereby improving combustion efficiency.
The second patent presents two embodiments of induction systems for internal combustion engines, specifically aimed at enhancing charging efficiency at low speeds and throttle openings. Each embodiment features a plenum chamber that connects with the induction system between the throttle valve and the chamber it serves. A control valve regulates the communication of the plenum chamber with the induction passage, effectively restricting communication when the throttle valve is fully open.
