ABSTRACT:
A control signal is generated to actuate a solenoid-operated valve at an angle phase of rotation of an engine for cutting off a fuel supply to an engine cylinder. The control signal is determined by a reference angle signal produced at a reference angle of rotation of the engine, and a rotational angle signal produced for each crank angle. Rotational angle signals are counted which are produced after each reference angle signal before the angle phase is reached with any remainder angle smaller than the crank angle. The remainder angle is converted into a time based on an average number of r.p.m. of the engine at the time the conversion is effected. The control signal is issued upon elapse of the counted rotational angle signals and the converted time. A ratio of an instantaneous number of r.p.m. of the engine in the vicinity of the angle phase to an average number of r.p.m. of the engine is issued and used for correcting the time converted from the remainder angle with the ratio.
