Abstract
PURPOSE:To stabilize regardless of the position of a combustion cylinder and detect knocking in such a way that a combustion cylinder detector is installed to detect the cylinder in combustion stroke, and knocking discriminating level is changed from the positioning relation with the combustion cylinder and the knocking detector. CONSTITUTION:Output signals from a knocking detector 1 are removed except knocking frequency through a filter 51, and detecting signals from a combustion cylinder detector 2 makes the desired discriminating level through a waveform shaping circuit 55 by a cylinder discriminating level circuit 56. Said result is given as input to a knocking detection circuit 52, and knocking pulses to be given as output comes into an ignition timing control U/D counter 53 to increase one count. In case where knocking pulses do not generate, one count is decreased by a progressive angle timer 54. The output is arithmetically operated together with reference ignition signals from a distributor 3 in the delay angle arithmetic circuit 58, in the event that knocking occurs, the angle is delayed, but if there is not cause of it, signals in progressive angle comes into a closing angle control circuit 59, the closed angle is controlled, and it is sent as ignition signals to an igniter 4.
