Abstract

A device for controlling an internal combustion engine of a motor vehicle comprises a sensor disk rotating with the shaft of the engine and a stationary signal receiving element scanning signals from the sensor disk. Sensing elements are positioned on the sensor disk. The number of these elements is proportional to the number of cylinders of the engine. Each sensing element includes a sickle-shaped portion and a lug coordinated with the signal receiving element. The control system is formed as an assembly of prefabricated structural components.
