Abstract
The present invention provides an internal combustion engine control device which is capable of implementing a plurality of functions desired to the internal combustion engine. An adder unit determines a total energy E_total that should be generated by the engine by adding a target work, a target exhaust energy and cooling heat loss, which are calculated in a style of energy. A target fuel supply quantity calculation unit calculates a target fuel supply quantity necessary for generating the E_total. A target intake quantity calculating unit calculates a target intake quantity based on the target fuel supply quantity and a target A/F. A target ignition timing calculation unit calculates a target ignition timing necessary for realizing the target exhaust energy.
