ABSTRACT:
The fluctuations of the rotational speed of the engine crankshaft are detected by two torsionally coupled inertial discs with fiducial markers. The movement of these markers past an inductive sensor provides a signal which is fed to a logical control circuit that controls the generation of a voltage which is characteristic of the actual crankshaft fluctuations. This actual voltage is amplified and rectified and compared with a set-point voltage generated by a set-point generator. The resulting signal is used to control an integrating circuit which may engage the fuel injection system of the exhaust gas recycling system of the engine to change the fuel-air mixture so as to return the actual voltage value to the set-point value.
