摘要： PROBLEM TO BE SOLVED: To judge a deterioration level of a catalyst more precisely in an exhaust emission control system of an internal combustion engine having an exhaust emission control device installed to an exhaust passage of the internal combustion engine and constituted to include a catalyst having an oxidizing function.
SOLUTION: This system comprises a CO
2 concentration detection means for detecting concentration of CO
2 in an exhaust air flown from a catalyst. When a reducing agent is supplied to the catalyst, the concentration of CO
2 in the exhaust air flown from the catalyst assumed in an initial condition is estimated based on an intake air volume of the internal combustion engine, a volume for supplying the reducing agent to the catalyst, and a temperature of the catalyst (S104). It is determined that a deterioration level of the catalyst is larger, as a difference between the estimated value and a value detected by the CO
2 concentration detection means is larger (S106).

摘要： PROBLEM TO BE SOLVED: To provide an emission control device for reducing a quantity of sulfur component included in exhaust gas flowing out of a sulfur component hold-back agent even if a sulfur component holding quantity of the sulfur component hold-back agent increases. SOLUTION: The sulfur component hold-back agent 61 for holding the sulfur component included in the flowing-in exhaust gas and an NOx hold-back agent 62 for holding NOx in the flowing-in exhaust gas are arranged in an exhaust passage of an internal combustion engine. NOx separating processing is performed for adjusting the air fuel ratio of the exhaust gas flowing in the sulfur component hold-back agent so that the air fuel ratio of the exhaust gas flowing in the NOx hold-back agent becomes almost the stoichiometric air fuel ratio or rich when separating NOx held in the NOx hold-back agent. Here, when the sulfur component holding quantity of the sulfur component hold-back agent is a prescribed quantity or more, the air fuel ratio of the exhaust gas flowing in the sulfur component hold-back agent is prohibited from becoming almost the stoichiometric air fuel ratio or rich.
