Abstract

PURPOSE: To detect the knocking of an internal-combustion engine at accurately by a method wherein the discrimination between the presence and absence of the knocking is performed by a function computing circuit.
CONSTITUTION: An ignition timing calculation circuit 10 determines a delay angle or an advance angle of the ignition angle for an ignition device 3 in accordance with a detection signal fed from a knocking detector 2. A knocking detection circuit 14 incorporates the function computing circuit 24 which is inputted with a signal from the knocking detector 2 and by which the input signal having linearity to a vibrating force is converted into a non-linear output signal. Whether the knocking is generated or not is discriminated by the output signal.
