Internal combustion engine

摘要

A first combustion mode in which an amount of an EGR gas within a combustion chamber (5) is more than the amount of the EGR gas when a generation amount of a soot becomes peak and the soot is hardly generated, that is, a low temperature combustion, and a second combustion mode in which the amount of the EGR gas within the combustion chamber (5) is less than the amount of the EGR gas when the generation amount of the soot becomes peak are selectively performed. Accordingly, a torque change amount of the engine output is detected by a detecting means (52, 40) when the first combustion mode is performed and a fuel injection timing is controlled so that the torque change amount becomes within a predetermined range.
