Title: Innovations of Tuneyuki Tanizawa
Introduction
Tuneyuki Tanizawa is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of exhaust gas purification technology. With a total of two patents to his name, his work focuses on improving the efficiency of catalysts used in automotive applications.
Latest Patents
Tanizawa's latest patents include innovative catalysts designed for purifying exhaust gases. The first patent describes a catalyst that features a heat-resistant support, a porous layer, and a noble metal catalyst ingredient. This catalyst also incorporates an NO.sub.x storage component, which is crucial for enhancing the purification process. In fuel-lean atmospheres, the catalyst oxidizes NO to NO.sub.2, which is then stored and later released in fuel-rich conditions to react with hydrocarbons and carbon monoxide. This design significantly improves the NO.sub.x purifying performance.
The second patent outlines a similar catalyst but emphasizes the strategic placement of ceria (CeO.sub.2) away from the noble metal catalyst. This arrangement allows for controlled oxygen release, further optimizing the catalyst's performance in various atmospheric conditions. Both patents reflect Tanizawa's commitment to advancing automotive technology and reducing harmful emissions.
