摘要： An exhaust gas after-treatment device 31 including an oxidation catalyst 31a and a DPF 31b in order from an upstream side is provided in an exhaust passage 15 of an internal combustion engine 10. A target value Et of an EGR rate E in EGR control is set to be a second EGR rate E2 higher than a first EGR rate E1 at the time of a normal operation of the internal combustion engine 10 and the EGR control is performed, in a case where a catalyst index temperature T that indexes a temperature of the oxidation catalyst 31a falls within a set temperature region Rab between a lower limit set temperature Ta and an upper limit set temperature Tb which are preliminarily set, and where an estimated PM deposition amount V of the DPF 31b is less than a preliminarily set regeneration start threshold value Vc, after an operation state of the internal combustion engine 10 transitions from a traveling operation state to an idling operation state. Thereby, in the idling operation state after travel of a vehicle, generation of NO 2 by the oxidation catalyst 31a included in the exhaust gas after-treatment device 31 of the exhaust passage 15 is decreased, and emission of NO 2 to the atmosphere is suppressed.

摘要： A nitrous oxide (N2O) removal catalyst composite is described, which includes: a N2O removal catalytic material on a carrier, wherein the catalytic material comprises a platinum group metal (PGM) component on a ceria-containing support having a single phase, cubic fluorite crystal structure. The catalytic material is effective to decompose nitrous oxide (N2O) to nitrogen (N2) and oxygen (O2) and/or to reduce N2O to N2 and water (H2O) and/or (CO2) under conditions of an exhaust stream of an internal combustion engine operating under conditions that are stoichiometric or lean with periodic rich transient excursions. Methods of making and using the same are also provided.
