ABSTRACT:
A combustion control system includes a waveform shaping device for producing an ON signal from an ion current detected value, a down timing detecting device for detecting down timings of the ON signal, an operating device for converting the down timings into times elapsing from a reference crank angle, mask time section setting device for setting a mask time section corresponding to a combustion period in accordance with a running condition of the internal combustion engine, a selecting device for selecting at least one of said down times detected within the mask section, and a determining device for determining a combustion parameter of said internal combustion engine in accordance with the combustion ending time, whereby the combustion state of each cylinder is detected from the combustion ending time detected by the mask time section to determine the combustion parameter so as to suppress a combustion change. In this configuration, by operating a small quantity of data, an inexpensive and accurate combustion control system for an internal combustion engine can be obtained.
