Deterioration of a selective catalytic reduction (SCR) catalyst (5) can be diagnosed with sufficient accuracy, by making use of a sensor (7) for measuring an air fuel ratio of exhaust gas flowing into an exhaust gas purification apparatus, which is equipped with the SCR catalyst (5), and a further sensor (8) for measuring an air fuel ratio of exhaust gas flowing out from the exhaust gas purification apparatus. In an exhaust gas purification apparatus for the exhaust gas purification apparatus, in a time period in which inducement-processing is carried out which is to induce a water gas shift reaction in a catalyst disposed at the upstream side of the SCR catalyst (5), by changing an air fuel ratio of exhaust gas discharged from an internal combustion engine (1) from a lean air fuel ratio into a predetermined rich air fuel ratio, an air fuel ratio of exhaust gas flowing into the SCR catalyst (5) and an air fuel ratio of exhaust gas flowing out from the SCR catalyst (5) are measured by said air fuel ratio sensors (7, 8), respectively, and deterioration of the SCR catalyst (5) is diagnosed based on a difference between the measured values of these sensors, wherein the inducement-processing is carried out when the amount of NH3 adsorption in the SCR catalyst (5) is equal to or less than a predetermined amount.

| PURPOSE:To maintain air-fuel ratio at a proper value so as to reduce the quantity of exhausted waste contaminant as much as possible by performing air-fuel ratio feedback control using an integration constant which is larger during transient operation of an internal combustion engine than while the engine is in its steady state. CONSTITUTION:During air-fuel ratio feedback control under transient operating conditions, a correction factor IMET(<1) for correcting an integration constant used for setting an air-fuel ration feedback correction factor alpha is set in proportion to the density of alcohol detected by an alcohol sensor 7. Next, a basic integration constant IO found by retrieval, etc., from a map according to engine speed N and a basic fuel injection quantity TF is multiplied by the correction factor IMET so as to set an integration constant (I) and then the air-fuel ratio feedback correction factor alpha is renewed by a value obtained by addition of the integration constant (I) to the previous value of the correction factor alpha, and then air-fuel ratio feedback control is started with the integration constant (I) being maximized in the same way as with gasoline in order to enhance responsiveness. | ||||||

| An internal combustion engine is equipped with an exhaust purification catalyst (20), an upstream air-fuel ratio sensor (40), a downstream air-fuel ratio sensor (41), and sensor heaters (56) of the upstream air-fuel ratio sensor (40) and the downstream air-fuel ratio sensor (41). A control device comprises an air-fuel ratio control part configured to control the air-fuel ratio of the exhaust gas and a heating control part configured to control the heating of the air-fuel ratio sensors.

| An engine control system of a vehicle includes a fuel control module that controls fuel injection of a first cylinder of an engine based on a first target air/fuel ratio that is fuel lean relative to a stoichiometric air/fuel ratio and that controls fuel injection of a second cylinder of the engine based on a second target air/fuel ratio that is fuel rich relative to stoichiometry. The first cylinder outputs exhaust to a first three way catalyst (TWC), and the second cylinder outputs exhaust to an exhaust gas recirculation (EGR) valve. An EGR control module controls opening of the EGR valve to: (i) a second TWC that reacts with nitrogen oxides (NOx) in the exhaust and outputs ammonia to a selective catalytic reduction (SCR) catalyst; and (ii) a conduit that recirculates exhaust back to an intake system of the engine. | ||||||
