摘要： A three-way catalyst (20) and an NO x adsorption catalyst (22) are disposed in an engine exhaust passage. In a predetermined low-load engine operation area, combustion in a combustion chamber (5) is carried out at a lean base air-fuel ratio and an air-fuel ratio in the combustion chamber (5) is changed to a rich range at the time of discharging NO x from the NO x adsorption catalyst (22). In a predetermined high-load engine operation area, the air-fuel ratio in the combustion chamber (5) is controlled to a theoretical air-fuel ratio in a feedback manner. In a predetermined middle-load engine operation area, the combustion in the combustion chamber (5) is carried out at the base air-fuel ratio lower than the base air-fuel ratio in the low-load engine operation area and the air-fuel ratio in the combustion chamber (5) is changed to the rich range with a period shorter than a rich period of the air-fuel ratio for discharging NO x in the low-load engine operation area.

摘要： In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged. At the time of engine operation, the amplitude of change of the concentration of hydrocarbons which flow into the exhaust purification catalyst (13) is made to become within a predetermined range of amplitude by control of at least one of the injection time and injection pressure of hydrocarbons from the hydrocarbon feed valve (15). In this case, when only the injection time of hydrocarbons is controlled, the injection time of hydrocarbons under the same engine operating state is made longer the higher the temperature of the exhaust purification catalyst (13).
