Transmitter arrangement for cylinder identification in an internal

Control system for the electric fuel pump of an internal combustion

A control system for an internal combustion engine which includes a crankshaft sensor for sensing a crankshaft transmitter disk and a camshaft sensor for sensing a camshaft transmitter disk. Both sensors supply signals to a control device which calculates ignition and injection signals based upon operating parameters, such as engine load and rotational speed, with the rotational speed being based on the signals for the crankshaft sensor or camshaft sensor. In case of crankshaft sensor failure, an emergency function in the control device simulates the crankshaft signals based on the signals from the camshaft sensor. Preferably, the number of segments on the camshaft transmitter disk are equal to the number of cylinders of the engine.
