Abstract

To provide a signal representative of angular crankshaft position from an ignition distributor, independently of change of ignition timing, the ignition distributor includes a further or additional rotating transducer system (8, 9, 10, 11), for example a rotating disk (8) positively coupled to the shaft (3) of the distributor. The disk (8) carries markers (10) which are picked up by an optic, magnetic (Hall generator) or inductive pick-up (9). To provide a reference marker output, for example a reference, e.g. TDC position of a reference piston, the rotating disk (8) can carry an additional reference marker (10a) picked up by a reference pick-up (9a) which can be similar to the other pick-ups used in the construction. The specific crankshaft position signals are especially suitable and desirable if the engine is coupled to an engine knock sensing and knock prevention system (KS).
