    >

    A method of operation of a dual fluid fuel injection system arranged to supply fuel to a cylinder of an internal combustion engine, the dual fluid fuel injection system being controllable to effect fuel metering events and fuel delivery events. The method comprises operating the dual fluid fuel injection system so as to have at least one fuel delivery event during each engine cycle and to have fewer than one fuel metering event, on average, per engine cycle. An electronic control unit for implementing the method is also described. The method and control unit allow dynamic range of a fuel metering injector, where included within the dual fluid fuel injection system, to be extended.

    CLAIMS:
    1 . A method of operation of a dual fluid fuel injection system arranged to supply fuel to a cylinder of an internal combustion engine, the dual fluid fuel injection system being controllable to effect fuel metering events and fuel delivery events, the method comprising operating the dual fluid fuel injection system so as to have at least one fuel delivery event during each engine cycle and to have fewer than one fuel metering event, on average, per engine cycle.
    2. The method according to claim 1 being implemented for low engine load /speed and high engine load/speed engine operating conditions. 3. The method according to claim 1 or 2 wherein a single fuel metering event provides fuel for a plurality of engine cycles.
    4. The method of claim 3 wherein relative length of fuel de of claim 12 or 13 wherein said ECU recalculates a map for controlling operation of said dual fluid injection system each said successive engine cycle.
