ABSTRACT:
In order to accomplish aforementioned and other objects, a spark ignition timing control system, according to the present invention, is adapted to perform spark ignition timing control for an internal combustion engine combustioning a blended fuel, such as gasoline/alcohol mixture fuel. The control system performs MBT control by adjusting spark advance angle toward a maximum pressure point in feedback manner. The spark advance angle derived in MBT control is modified with a correction value derived on the combustion propagation speed which is variable depending upon blending ratio of one of the fuels in the blended fuel.
