ABSTRACT:
A fuel control system includes devices that generate parameter signals. The parameter signals include an engine runtime signal and at least one of an engine load signal, a temperature signal and a barometric pressure signal. A modification module generates a modification signal based on the parameter signals. A control module compensates for a current fuel volatility by adjusting a current air/fuel mixture of an engine based on the modification signal.
