ABSTRACT:
A combustion control apparatus operates an internal combustion engine in a split retard combustion mode during regenerating an exhaust purifier such as a particulate filter. In the split retard combustion mode, the combustion control apparatus controls a first fuel injection to cause preliminary combustion at or near top dead center, and controls a second fuel injection to cause main combustion after an end of the preliminary combustion. In this manner, the combustion control apparatus controls an exhaust gas temperature, or an exhaust air-fuel ratio, without increasing exhaust smoke. During the split retard combustion mode, the combustion control apparatus controls an EGR rate of the engine. The EGR rate in the split retard combustion mode is set lower than in the normal combustion mode, in each operating point of the engine.
