Compression ignition type engine

摘要

A compression ignition type engine, wherein a first combustion where the amount of the recirculated exhaust gas supplied to the combustion chamber is larger than the amount of recirculated exhaust gas where the amount of production of soot peaks and almost no soot is produced and a second combustion where the amount of recirculated exhaust gas supplied to the combustion chamber is smaller than the amount of recirculated exhaust gas where the amount of production of soot peaks are selectively switched between. When the first combustion is switched to the second combustion or the second combustion is switched to the first combustion, the amount of fuel injection is reduced and the amount of reduction of the output torque of the engine is compensated for by the output torque of an electric motor.
