ABSTRACT:
A control device for a multicylinder engine comprising a knocking detector for detecting the occurrence of knocking, a crank angle sensor for generating a signal indicative of the crank angle, an engine operating condition control device for governing the engine operating condition, and a control circuit for identifying one of the engine cylinders in which knocking has actually occurred, in dependence on both outputs from the detector and the crank angle sensor. The control circuit operates to cause the engine operating condition control device to control the at least one of the engine cylinders when the output from the detector is lower than a predetermined value, but to control all of the engine cylinders when it is higher than the predetermined value.
