ABSTRACT:
An apparatus and method for determining an engine operation control based engine revolution displacement for a multi-cylinder four-stroke internal combustion engine are disclosed in which a reference crank angle sensor is disposed on an engine crankshaft so as to output a reference signal which corresponds to a predetermined crank angular position with respect to a top dead center of each cylinder whenever the engine has revolved through a set crank angular displacement according to the number of cylinders (720.degree./6=120.degree., in the case of a six-cylinder engine). A unit crank angle sensor is disposed on the engine crankshaft so as to output a unit angle (1.degree. or 2.degree.) of the engine crankshaft revolution, a first counter (C1) is built in a gate array (IC-package or gate arrary IC) so as to count the unit angular signal (POS) upon receipt of the reference signal (REF) and so as to be reset to zero when a count value of the first counter has reached a predetermined count value corresponding to the set crank angular displacement and when the first counter receives the subsequent reference signal.
