Title: Kenichi Sato: Innovator in Exhaust Gas Purification Technology
Introduction
Kenichi Sato is a prominent inventor based in Yokohama, Japan, known for his significant contributions to the field of exhaust gas purification technology. With a total of 14 patents to his name, Sato has made remarkable advancements that enhance the efficiency and effectiveness of internal combustion engines.
Latest Patents
One of Sato's latest patents is an exhaust gas purification control device for an internal combustion engine. This innovative device includes a detection unit that monitors the air-fuel ratio or the rich/lean state of exhaust gas flowing from a first catalyst. It features an estimating unit that assesses the oxygen adsorption amount on both the first and second catalysts. Additionally, the enrichment control unit adjusts the richness of injected fuel based on the estimated oxygen adsorption, ensuring optimal performance even after reaching a stoichiometric air-fuel ratio.
Another notable patent is a diagnostic apparatus for an exhaust gas purification system of an internal combustion engine. This apparatus comprises a main exhaust passage and a main catalytic converter, along with a bypass exhaust passage and a bypass catalytic converter. A valve regulates the flow within the main exhaust passage, while sensors measure the air-fuel ratios in both the bypass and main catalytic converters. The controller uses this data to determine if the valve leaks exhaust gas, thereby enhancing the reliability of the exhaust gas purification system.
