<p>Oscillation of the engine is detected by an oscillation sensor (4) which outputs a signal representing the oscillation of the engine. The maximum value of the output of the oscillation sensor during combustion period in each cycle is detected. The maximum values obtained in a predetermined number of cycles are stored in a memory and knock occurrence is determined on the basis of the predetermined number of maximum values output from the memory.</p> |
