IPC: F01N3/24
Filed: 2002-04-24
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem of inadequate cleaning of HC which is easily discharged since HC desorption from an HC trap agent starts before a ternary catalyst reaches an activated temperature after cold start of an engine in an engine exhaust cleaning system using an HC trap catalyst.  <P>SOLUTION: In an catalyst converter subjecting coating of the HC trap agent to a catalyst carrier, one or more slits are formed so as to cross a cell of the catalyst carrier.
