Title: Hitoshi Satou: Innovator in Exhaust Gas Purification Technology
Introduction
Hitoshi Satou is a prominent inventor based in Fujisawa, Japan. He has made significant contributions to the field of internal combustion engine technology, particularly in exhaust gas purification systems. With a total of eight patents to his name, Satou's work has had a considerable impact on environmental sustainability in automotive engineering.
Latest Patents
One of Satou's latest innovations is an exhaust gas purification device for internal combustion engines. This device includes an exhaust gas after-treatment system that features an oxidation catalyst and a diesel particulate filter (DPF). The system is designed to enhance the efficiency of exhaust gas treatment by incorporating an exhaust pipe injector that feeds fuel to the oxidation catalyst. A control unit manages the regeneration of the filter, ensuring that it operates under optimal conditions. If the filter is not in a regeneration-possible state, the control unit halts the regeneration process until the necessary conditions are met.
Another notable patent is the diesel particulate filter system, which aims to reduce clogging of the DPF while enhancing user convenience. This system includes an accumulated particulate matter (PM) quantity estimator that assesses the PM levels during idle states. If the estimated PM quantity exceeds a predetermined threshold, the system initiates a long low idle forced regeneration process. This innovative feature allows for automatic regeneration of the DPF even while the vehicle is in motion, thereby improving overall efficiency.
