Abstract
A compression ignition type engine selectively switching between a first combustion where an amount of recirculated exhaust gas supplied in a combustion chamber ( ) is greater than an amount of recirculated exhaust gas where the amount of production of soot peaks and a second combustion where the amount of recirculated exhaust gas supplied in the combustion chamber ( ) is smaller than the amount of recirculated exhaust gas where the amount of production of soot peaks. A particulate filter ( ) carrying a NO absorbent ( ) is arranged in the engine exhaust passage. When SOx should be released from the NOx absorbent ( ) and there is leeway in the electrical energy stored in the battery ( ), the first combustion is performed even when the second combustion should be performed and the drop in output power of the energy is made up by the output torque of an electric motor ( ).
