ABSTRACT:
Disclosed is an apparatus for detecting the reference rotational angle for each cylinder in a multiple-cylinder internal combustion engine, in which a reference pulse signal is output at a position of a predetermined rotational angle of the engine at a specific stroke of each cylinder synchronously with the revolution of the engine, a cylinder-discriminating pulse signal is put out just after termination of specific one of the reference pulse signal, the precedent and present values of elements, concerning the time, of the pulse signal are detected, and when the present value is smaller than the precedent value by at least a predetermined value, discrimination of cylinders is performed.
