Title: Kenji Sugiura: Innovator in Internal Combustion Engine Technology
Introduction
Kenji Sugiura is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of internal combustion engine technology. With a total of 2 patents to his name, Sugiura's work focuses on enhancing the efficiency and effectiveness of exhaust gas purification systems.
Latest Patents
Sugiura's latest patents include an "Exhaust Gas Purifying Apparatus for Internal Combustion Engine" and a "Controller for Internal Combustion Engine." The controller patent addresses the issue of NOx purifying device deterioration due to sulfur contamination. It introduces a specific operating state flag that, when activated, varies the air-fuel ratio of the mixture supplied to the engine. This variation occurs at intervals of three seconds, alternating between leaner and richer than the stoichiometric air-fuel ratio. Additionally, when the temperature of the NOx purifying device exceeds a certain threshold, the system maintains a richer air-fuel ratio for a designated recovery period. The exhaust gas purifying apparatus patent outlines a method for determining whether the engine is currently operating in a lean state and executes reduction enrichment of NOx before stopping the engine.
