Abstract
An ignition control system for a spark ignition internal combustion engine has: over-advancing means for over-advancing an ignition time for a cylinder of the internal combustion engine beyond an MBT; obtaining means for obtaining an adhering fuel amount that is the amount of fuel that adheres to the inner face of the cylinder of the internal combustion engine; and controlling means for controlling the over-advancing means to execute the ignition time over-advancement when the adhering fuel amount obtained by the obtaining means is equal to or larger than a predetermined amount.
Claims26
An ignition control system for a spark ignition internal combustion engine, comprising:
- an over-advancing portion configured to over-advance an ignition time for a cylinder of the internal combustion engine beyond an MBT;
- an obtaining portion configured to obtain an adhering fuel amount that is the amount of fuel that adheres to the inner face of the cylinder of the internal combustion engine;
- and
- a controller configured to control the over-advancing portion to execute the ignition time over-advancement when the adhering fuel amount obtained by the obtaining portion is equal to or larger than a predetermined amount.
