  • Fuel blending ratio inferring method
    Patent number: 6016796
    Abstract: A fuel blending ratio inferring method responsive to an air/fuel feedback control system for an internal combustion engine is disclosed having a feedback correction loop generating a feedback variable derived from an output of an exhaust gas sensor. A fuel blending ratio is inferred in response to a refueling indication by observing the size and magnitude of the feedback variable. Thus, the effect of the fuel blend can be isolated from other errors in the feedback control system.

  • Fuel control system
    Patent number: 5934255
    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.
