Abstract: A fuel metering apparatus having a metering chamber to hold fuel for subsequent delivery to an engine. A rigid metering member projecting into the chamber linearly movable relative to the chamber to vary the extent of projection of the metering member into the chamber to thereby control the quantity of fuel displaceable from the chamber. An inextensible flexible member secured to the metering member and a motor operated in accordance with the engine fuel demand, the motion of the motor being transmitted to the metering member through the inextensible flexible member. The inextensible flexible member is preferably adjustably coupled to the motor so the limit of movement of the metering member may be set as required.

Abstract: A method of delivering fuel to an internal combustion engine comprising delivering individual metered quantities of fuel into a conduit, and propelling each individual metered quantity of fuel along the conduit by an individual gas pulse. During the time interval between the respective gas pulses that deliver the metered quantities of fuel there is established a secondary gas flow in the conduit so as to limit variations in the quantity of fuel retained in the conduit as the metered quantity of fuel varies with engine fuel demand.
