Patent number: 8186149Abstract: A NOx reduction system comprises NOx treatment catalyst and air-fuel ratio control switch for changing the air-fuel ratio of an exhaust gas to a lean or rich state. The NOx treatment catalyst comprises at least a first catalyst layer containing a solid acid catalyst capable of adsorbing ammonia and a second catalyst layer containing a noble metal and a cerium oxide material. The second and the first catalyst layer are stacked in that order on a carrier, and the first catalyst layer constitutes the uppermost layer. NOx is passed through the first catalyst layer in the lean state and is temporarily stored in the second catalyst layer. Thereafter, in the rich state, NOx is converted to NH3 and is restored in the first catalyst layer. When the state is again returned to the lean state, NH3 is converted to nitrogen which is finally released from the first catalyst layer.Type: GrantFiled: July 30, 2007Date of Patent: May 29, 2012Assignee: Honda Motor Co., Ltd.Inventors: Naohiro Satoh, Osami Yamamoto, Koichi Inaba, Hiroshi Ohno
