ABSTRACT:
An apparatus for detecting combustion in an internal combustion engine which comprises: a plurality of cylinders wherein an ignition control is performed being synchronized with a revolution number of the internal combustion engine; and an ionic current detector installed at an ignition plug of at least one cylinder of the plurality of cylinders; the ionic current detector including a device for generating a voltage which corresponds to a level of an ionic current generated by the ignition plug, a device for generating a threshold value which is a combustion determining standard, and a comparator which generates an output signal that shows a combustion state, by comparing the voltage with the threshold value; the device for generating a threshold value is composed of a threshold level variable circuit which generates a threshold value corresponding to a running condition of the engine.
