Ignition timing control system for an internal combustion engine

摘要

An ignition timing control system for use in an internal combustion engine equipped with a supercharger, including intake air quantity detecting means for detecting an amount of intake air flowing in an intake air passage defined at the upstream side of the supercharger, engine speed detecting means for detecting the engine speed, ignition timing control means for controlling the ignition timing on the basis of outputs from the intake air quantity detecting means and the engine speed detecting means, intake air condition detecting means for outputting a signal reflecting a substantial pressure of the intake air drawn into a combustion chamber of the engine, and correcting means for correcting the ignition timing in compliance with an output from the intake air condition detecting means.
