ABSTRACT:
An acceleration sensor senses mechanical noise components and knock signals originating from an internal combustion engine. An output from a filter used for attenuating the noise components is applied to both an analog gate which is closed for some time period after each ignition time by a gate timing controller and to a noise level detector. An outpt from the analog gate is compared with a DC voltage due to the attenuated noise components delivered by the detector to form pulses. After having been integrated, the pulses shift a phase of an ignition signal to cause the ignition timing to be retarded.
