ABSTRACT:
An ignition timing control apparatus for an internal combustion engine having an in-cylinder injector for injecting a fuel into a cylinder and an intake port injector for injecting a fuel into an intake port is configured to correct a basic ignition timing, having been determined corresponding to an operation state, in accordance with a fluctuation of at least one factor affecting the combustion rate selected from a coolant temperature, an intake air temperature and an EGR (exhaust gas recirculation) amount, to set a final ignition timing. The correction amount of the ignition timing is set greater for the port injection than for the in-cylinder injection.
