Provided is an engine control device capable of, when performing control of an in-cylinder oxygen concentration according to engine operation state, controlling an engine to accurately realize vehicle behavior intended by a driver, while suppressing generation of knock noises due to abnormal combustion. The engine control device comprises: a basic target torque-determining part (61) configured to determine a basic target torque based on a driving state of a vehicle including manipulation of an accelerator pedal; a torque reduction amount-determining part (63) configured to determine a torque reduction amount based on a driving state of the vehicle other than the manipulation of the accelerator pedal; a final target torque-determining part (65) configured to determine a final target torque based on the basic target torque and the torque reduction amount; and an engine control part (69) configured, based on a fuel injection parameter preliminarily set correspondingly to an operation state of an engine, to control a fuel injector to enable the engine to output the final target torque, and, when the final target torque changes correspondingly to a change in the torque reduction amount, to correct the fuel injection parameter.
