ABSTRACT:
A fuel control system and method for an engine having a returnless fuel system uses a fuel blend sensor to adjust a desired air/fuel ratio to allow continuous fuel blend changes. Engine operating conditions are monitored and used to track the movement of small fuel quantities from the fuel blend sensor to the fuel injectors. The system and method use the cells in the stack to represent the volume of the fuel quantities and their corresponding measured fuel blend.
