Abstract
A fuel control for an engine using a liquid mixture of two fuels, such as gasoline and methanol, having different volumetric heat contents is responsive to a fuel compostion sensor to update a stored engine fuel control parameter. When a significant change in fuel composition is sensed, the stored engine fuel control parameter is not updated for a fuel transition time duration to allow the unchanged fuel still in the conduit between the sensor and engine to be used with the unchanged stored engine fuel control parameter.
