Abstract
A device for controlling ignition or fuel injection and the like of an internal combustion engine includes an angular position sensor of a shaft of the engine. The sensor is in the form of a disc rotating together with the shaft and being provided on its periphery with as many radially projecting segments separated by gaps as many cylinders has the engine. A gap between the segments is provided with a single sloping ramp terminating with a steep flank. The flank of one segment and the steep flank of the ramp cooperate with a detector which generates a marking pulse coordinating during single rotation of the shaft the distribution of control pulses to respective cylinders.
