Abstract
A controller for an internal combustion engine that switches combustion modes in accordance with the running conditions of the engine. When there is a need to reduce the engine torque, the controller decreases the torque by a predetermined torque reduction method. The controller decreases the engine torque by a first torque reduction method when the engine is in a first combustion mode. When the engine is in a second combustion mode, the controller reduces the torque by a second torque reduction method. The controller sets a first control amount, which corresponds to the torque reduction requirement, according to one of the first and second torque reduction methods. The controller converts the first control amount into a second control amount, which corresponds to the other torque reduction method.
