摘要： An exhaust passage of an internal combustion engine is provided with an upstream side three-way catalyst capable of purifying exhaust gas and a particulate filter (PM filter) for trapping particulate matter PM contained in exhaust gas. Catalyst warm-up control is exercised for the purpose of warming up mainly the upstream side three-way catalyst at cold start. Filter regeneration control for removing the particulate matter PM accumulating on the particulate filter from the filter is exercised at the cold start after the catalyst warm-up control is exercised.

摘要： The air-fuel ratio of exhaust gas supplied to a catalyst is alternately and actively switched between a rich state value and a lean state value. In conjunction with the performance of this active air-fuel ratio control, the oxygen storage capacity of the catalyst is measured. Whether the catalyst is normal or abnormal is determined by comparing the measured value of the oxygen storage capacity with a predetermined determination value. The temperature of the catalyst is acquired, and the determination value is set based on the acquired catalyst temperature. The determination value is set so as to decreases with increasing catalyst temperature when the catalyst temperature is equal to or higher than a predetermined temperature.

摘要： An EGR apparatus includes a EGR passage for allowing part of exhaust gas discharged from a combustion chamber of an engine to an exhaust passage to flow in an intake passage and recirculate back to the combustion chamber, and an EGR valve provided in the EGR passage to regulate an EGR passage in this passage. The EGR valve includes a valve seat, a valve element to be seatable on the valve seat, and a step motor for driving the valve element to open and close. An electronic control device controls the EGR valve to repeat opening and closing of the valve element between a closing position and a small opening position in order to remove foreign matters adhered to the valve seat or valve element during deceleration fuel cutoff of the engine.
