ABSTRACT:
The fuel-air mixture of an engine in a motor vehicle is controlled on the basis of a signal related to the fluctuations in the cyclic variations of the average combustion chamber pressure. This signal is derived indirectly from a sensor which monitors the rotational speed of engine members, e.g. the crankshaft. In order to provide closed-loop control, there is provided a reference value which is adapted continuously to changing engine speed. In addition, a correction of the reference signal is made to account for varying degrees of damping induced by changing inertial masses coupled to the engine, in particular the elements of the transmission connected between the engine and the vehicle. The correction for damping is made on the basis of signals related to the prevailing gear ratio either by direct indication of the gearshift lever position or by measuring the rotational speeds of the input and output shafts of the transmission.
