Title: Shinichiro Otsuka: Innovator in Exhaust Purification Systems

Introduction

Shinichiro Otsuka, based in Wako, Japan, is a notable inventor with a strong focus on innovative exhaust purification systems for internal combustion engines. With a total of three patents to his name, Otsuka contributes significantly to the automotive industry, particularly in developing technologies that enhance engine efficiency and reduce emissions.

Latest Patents

Otsuka's latest patents include an advanced exhaust purification system which is designed to optimize the air-fuel ratio of exhaust gas. This system incorporates a Linear Air-Fuel (LAF) sensor positioned in the exhaust pipe to generate a signal corresponding to the air-fuel ratio of the exhaust gas. An upstream catalytic converter is integrated downstream of the LAF sensor to purify the exhaust, and an O2 sensor further enhances this process by providing additional data for the engine's control unit (ECU). The implementation of a Gasoline Particulate Filter (GPF) downstream ensures that the exhaust gas is purified effectively, converging to a target value near the stoichiometric ratio.

Another significant patent involves a gasoline particulate filter that outperforms traditional purification systems. This innovative GPF captures particulate matter in the exhaust gas utilizing a filter substrate defined by porous partition walls, which alternate openings to enhance the purification process. This filter is also equipped with a three-way catalyst that contains catalytic metals and composite oxides to improve its efficiency significantly.
