ABSTRACT:
An ignition timing control system for an internal combustion engine, which is capable of properly carrying out ignition timing control over a wide control range, thereby making it possible to improve fuel economy, and is capable of suppressing combustion fluctuation, thereby making it possible to improve drivability. Ignition timing is calculated, when the engine is determined to be in an intense combustion mode, such that a largest in-cylinder pressure angle at which in-cylinder pressure becomes largest converges to a target angle, whereas when the engine is determined to be in a weak combustion mode, the same is calculated by feedback, based on the target angle and combustion state parameters indicative of a combustion state in the cylinder.
