Title: The Innovative Contributions of Koichi Kasahara
Introduction
Koichi Kasahara is a prominent inventor based in Ogasa-gun, Japan. He has made significant contributions to the field of exhaust gas purification, holding a total of 13 patents. His work focuses on developing catalysts that enhance the efficiency of exhaust gas purification systems.
Latest Patents
One of his latest patents is a catalyst for purifying exhaust gases. This catalyst exhibits effective purifying characteristics even at low temperatures, such as immediately after an engine starts. It also demonstrates a high exhaust gas purifying ability. The catalyst allows hydrocarbon (HC) adsorbed at low temperatures to be released at high temperatures, where the released HC is then purified by a catalyst metal. This innovation provides an excellent advantage in purifying HC at low temperatures while maintaining high exhaust gas purifying efficiency.
Another notable patent is a catalyst for purifying exhaust gas, which includes both an upstream side catalyst and a downstream side catalyst. The upstream side catalyst is positioned to interact with the exhaust gas flow first and consists of a loading layer made of alumina containing barium and lanthanum, along with a noble metal such as palladium, rhodium, or platinum. The downstream side catalyst features a second loading layer composed of alumina containing lanthanum and cerium, along with another noble metal. This dual-catalyst system enhances the overall effectiveness of exhaust gas purification.
