Abstract
An output of a knocking discriminator is integrated by an integrator and the integrated value is reset by a resetting device in response to the operation in the ignition timing. The resetting operation of the resetting device is caused when both a cylinder pulse signal and an output signal from a micro-computer are inputted, and the resetting operation is cancelled when at least one of the signals disappears.
