ABSTRACT:
A combustion control device for internal combustion engines, comprising cylinder pressure detecting means for detecting the combustion pressure in a cylinder, crank angle detecting means for detecting a crank angle of the engine to be controlled, cylinder pressure monitoring means for finding and monitoring the waveform of the cylinder pressure based on the cylinder pressure detected by the cylinder pressure detecting means and a crank angle signal outputted from the crank angle detecting means, calculating means for calculating thermal efficiency based on the found waveform, and combustion control means for controlling the amount of fuel supply to the engine, ignition timing and the amount of exhaust gas recirculation, depending on the results of the calculation by the calculating means.
