Abstract:
A combustion control system for a diesel engine, comprising:a section for changing an ignition delay period defined as a time period between the instant when fuel injection is started and the instant when fuel starts burning;a section for changing a fuel injection rate defined as a quantity of fuel per unit of time;a section for detecting an ignition at which fuel starts burning;a section for controlling at least one of the section for changing the ignition delay period and the section for changing the fuel injection rate based on the detected ignition timing in a predetermined engine operation region to complete the fuel injection within the ignition delay period; andan engine EGR rate sensor to sense an EGR rate, wherein, when the sensed EGR rate increases, the timing of the fuel injection start is retarded toward top dead center of a compression stroke.
