Abstract
A control apparatus of an internal combustion engine which comprises: a pressure detecting means for detecting an inner cylinder pressure of each cylinder of a plurality of cylinders of the internal combustion engine; a crank angle detecting means for detecting a crank angle of the internal combustion engine; indicated mean effective pressure calculating means for calculating an indicated mean effective pressure of each cylinder from an output of the pressure detecting means and an output of the crank angle detecting means; load detecting means for detecting a load of the internal combustion engine; engine speed detecting means for detecting the internal combustion engine speed from an output of the crank angle detecting means; running condition determining means for determining a running condition of the internal combustion engine from an output of the load detecting means and an output of the engine speed detecting means; and averaging and controlling means for controlling at least one of an air-fuel ration and an ignition timing independently for each cylinder, so that an average value of each indicated means effective pressure of the plurality of cylinders is independently maxi…
