ABSTRACT:
A combustion knock detection signal for retarding the ignition timing of the internal combustion engine is disabled upon detection of an unstable condition of the storage battery voltage level. Switching means is provided which is operative in response to the unstable condition of the voltage level of the storage battery to disable the knock detection signal, thereby eliminating the production of a false knock detection signal during the engine cranking operation or a certain period after the starting of the engine in which the engine speed is lower than a predetermined level.
