Abstract
The present invention provides a method of compensating for changing fuels in a flexible fueled vehicle using a fuel composition sensor. The methodology detects and models an alcohol concentration transition at fuel injector tips following a fuel addition. The methodology improves the accuracy of engine fueling during an alcohol concentration change by delaying the application of a fuel composition multiplier until the fuel analyzed by the fuel composition sensor actually reaches the injectors.
