Abstract

See full text

The present invention provides an ignition timing control device and ignition timing control system for an internal combustion engine, capable of controlling an ignition timing of the engine promptly in response to a change in engine operating conditions. An ignition timing adjustment unit (43) is adapted to correct the ignition timing to a proper ignition timing in a retard region with reference to a maximum advance value based on a knocking signal outputted from a knocking detection unit (41) and a reference ignition signal (A) outputted from an external electronic control unit (37). The output signal from the ignition timing adjustment unit (43) can be thus promptly adjusted by retarding the ignition timing relative to a reference ignition timing given from the external electronic control unit (37) upon detection of engine knocking.
