More Information
Summary:PROBLEM TO BE SOLVED: To provide an exhaust emission control system capable of eliminating the need for a treatment of removing a sulfur constituent adsorbed by a lean NOx catalyst, and efficiently purifying exhaust emission in a reduced space. SOLUTION: The exhaust emission control system uses a composite oxide containing Li and Ti (hereinafter referred to as a Li and Ti composite oxide) as a high-level SOx trap material. More specifically, the exhaust emission control system includes a three-way catalyst or an oxidation catalyst, a SOx trap material, and a lean NOx catalyst. COPYRIGHT: (C)2009,JPO&INPIT
