ABSTRACT:
A method and apparatus for metering liquid fuel for delivery to an engine including delivering during each cycle a predetermined quantity of liquid fuel into a control chamber (71) charged with compressed gas, and thereafter, adjusting the quantity of fuel in the control chamber (71) in accordance with the engine load and/or speed to the required quantity per cycle, and discharging the adjusted quantity of fuel from the control chamber to an injection chamber (70) charged with compressed air for delivery to the engine combustion chamber. Conveniently, as the quantity of fuel is maintained in said control chamber (71) under pressure, the adjustment of the quantity of fuel is effected by opening a bleed valve 73 for a time period determined by the quantity of fuel required to be retained for delivery to the engine.
