Abstract
Three impulse transmitters are provided of which one co-acts with an impu mark on the flywheel, another with an impulse mark on the camshaft drive wheel and a third with the teeth of the ring gear on the flywheel of the engine. The impulse mark on the flywheel enables a precise determination of a reference angle position of the crank drive and the impulse mark on the camshaft pinion by triggering a window enables correct association within the working cycle which covers 720.degree. of crank-angle. The time spacing and amplitude of the triggered window are controlled by the tooth sequence on the ring gear.
