Abstract
A method for controlling the amount of spark advance for an internal combustion engine using a fuel mixture having a first and a second fuel of different volatility and volumetric energy content. The percentage of the first fuel in the fuel mixture is sensed and a desired base spark advance is determined. The desired base spark advance is adjusted as a function of the percentage of the first fuel to achieve a desired engine operating condition.
