ABSTRACT:
A pulse generator disk is secured to a crankshaft of an engine. The disk has notches representing a compression top dead center of each cylinder. A first magnetic pickup is provided for producing a first output signal in accordance with the notches. A rotary member is secured to a camshaft of the engine. The member has toothed portions comprising projections provided at positions corresponding to respective cylinders. The number of the projections in each toothed portion is set to represent a corresponding cylinder. A second magnetic pickup is provided for producing a second output signal in accordance with the projections. A control system is provided to respond to the second output signal determining the number of the projections to produce a cylinder designating signal, and to respond to the first output signal after the cylinder designating signal to produce a crank angle signal.
