Abstract:
1. A controller of an internal combustion engine having a heat generating unit projecting into a combustion chamber of the engine, the controller controlling an output of the engine and comprising: an abnormality detecting means for detecting an abnormality in the heat generating unit; a changing means for changing an operation mode of an actuator of the engine to control a state quantity in the combustion chamber of the engine such that lowering of startability due to the abnormality is compensated and such that the startability is improved on the occasion of starting of the engine if the abnormality in the heat generating unit is detected; and a valve characteristic varying means for varying a valve characteristic of an intake valve as the actuator, wherein the changing means includes a temperature raising means for raising temperature in the combustion chamber of the engine through an operation of the actuator of the engine, and the temperature raising means includes a compression ratio increasing means for increasing a compression ratio by operating the valve characteristic varying means.
