ABSTRACT:
An ignition timing control system is provided for an in-cylinder injection internal combustion engine to reduce a torque shock upon switching a fuel injection mode between a compression-stroke injection mode, in which an injection of fuel is performed primarily in a compression stroke, and an intake-stroke injection mode, in which an injection of fuel is performed primarily in an intake stroke, in accordance with an operation state of said internal combustion engine. The ignition timing control system is provided with an injection timing correction unit for correcting ignition timing of a spark plug, which is arranged in a combustion chamber, upon switching said fuel injection mode. A correction amount for ignition timing, by which said ignition timing is corrected by said ignition timing correction unit upon switching from said compression-stroke injection mode to said intake-stroke injection mode, is greater than a correction amount for ignition timing, by which said ignition timing is corrected upon switching from said intake-stroke injection mode to said compression-stroke injection mode.
