Abstract:
A controller of an engine having a plurality of combustion modes, one of which being selected depending on the running conditions of the engine, wherein the controller reduces the output torque of the engine according to one of a plurality of predetermined torque reduction methods when a torque reduction requirement is in effect, the controller comprising:control means for controlling the engine to decrease the output torque according to a first torque reduction method when the engine is in a first combustion mode and for controlling the engine to decrease the output torque according to a second torque reduction method when the engine is in a second combustion mode, which is different from the first combustion mode;setting means for setting a first control amount that corresponds to the torque reduction requirement according to the first torque reduction method; andconverting means for converting the first control amount to a second control amount according to the second torque reduction method;wherein the control means controls the engine according to the first control amount when the control means reduces the output torque by the first torque reduction method, and wherein the control means controls the engine according to the second control amount when the control means reduces the output torque by the second torque reduction method.
