Abstract:
A control device for an engine that produces power by burning a mixture of air and fuel in a combustion chamber, wherein the engine has an acceleration pedal and a throttle valve for adjusting an amount of intake air to the combustion chamber, and the engine switches a combustion mode between homogeneous charge combustion and stratified charge combustion, the control device comprising:a controller that controls the engine in accordance with a load acting on the engine, wherein, when homogeneous charge combustion is executed, the controller uses an intake parameter representing the amount of intake air as a value representing an engine load; and a computer for computing, as a virtual parameter, a value equivalent to the intake parameter presuming homogeneous charge combustion is executed with an amount of manipulation of the acceleration pedal when executing stratified charge combustion, wherein, when stratified charge combustion is executed, the controller uses the virtual parameter as a value representing the engine load.
