CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To sufficiently improve an output torque based on advance angle of fuel injection timing by suppressing ignition in an insuitable air-fuel ratio around an ignition plug accompanied with elongation of the time from the fuel injection to the ignition timing. SOLUTION: An electronic control unit(ECU) for controlling operation conditions of an engine 11 advances or retards a fuel injection timing and an ignition timing while controlling a fuel injection valve 40 and an ignitor 41a, for stabilizing a combustion state of the engine 11 and obtaining an output torque. The fuel injection timing and the ignition timing are advanced or retarded while keeping an interval between the fuel injection timing and the ignition timing constant. It is thus possible to prevent occurrence of ignition by an ignition plug 41 when the air-fuel ratio around the ignition plug 41 is not suitable for ignition at the time of advance angle of the fuel injection timing.
