ABSTRACT:
An internal combustion engine includes an engine control unit for setting a ratio of fuel injection quantity of both the injectors. The engine control unit includes a memory storing four sheets of ignition timing maps, with reference to which the maximum torque generation timing and knocking limit torque generation timing, at the direct injection injector (100%) and port fuel injection injector (100%), are calculated. The engine control unit further operates to calculate a correction amount from correction amount map, and calculates first interpolation value of the maximum torque generation timing at the above 100% operation time of both the injectors and second interpolation value of the knocking limit torque generation timing at the above 100% operation time of both the injectors. A value in which the correction amount is added to either one of the above first and second interpolation value on a delay angle side is calculated as ignition timing.
