Title: Akira Hashimoto: Innovator in Exhaust Emission Control Systems
Introduction
Akira Hashimoto is a prominent inventor based in Wako, Japan. He has made significant contributions to the field of internal combustion engine technology, particularly in exhaust emission control systems. With a total of 11 patents to his name, Hashimoto's work has had a substantial impact on reducing harmful emissions from vehicles.
Latest Patents
One of Hashimoto's latest patents is an exhaust emission control system designed for internal combustion engines. This system features a nitrogen oxide removing device that is integrated into the exhaust system. It effectively absorbs nitrogen oxides present in exhaust gases during lean operating conditions. The system estimates the change in sulfur oxide absorption based on the air-fuel ratio and engine operating conditions. When the estimated sulfur oxide amount reaches a predetermined value, it is removed from the nitrogen oxide removing device.
Another notable patent by Hashimoto involves an exhaust emission control system that includes a nitrogen oxides removing device and an oxygen concentration sensor. This sensor is positioned downstream of the nitrogen oxides removing device to monitor the oxygen concentration in the exhaust gases. The system determines the deterioration of the nitrogen oxides removing device based on the sensor's output after adjusting the air-fuel ratio from lean to rich conditions. It also identifies any abnormalities in the oxygen concentration sensor during rich air-fuel ratio conditions.
