Device for controlling internal combustion engines

In a device for controlling an internal combustion engine of a motor vehicle, comprising a sensor system including a sensor disk rotating with a shaft of the internal combustion engine, and a stationary signal receiving element cooperating with said sensor disk, said sensor disk including structural elements generating impulses and affected by said signal receiving element, said signal receiving element being connected to a control circuit for ignition, fuel injection or other system of the vehicle, the improvement comprising said structural elements being arranged on said sensor disk as additional segments and being formed each of at least two discrete but combinable elements, and the number of said discrete and combinable elements on said sensor disk being equal to the number of cylinders in said engine, said structural elements being formed so that a single additional control impulse or no additional control impulse is generated on a respective structural element.
