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