Abstract:
A fuel injection assembly for an internal combustion engine comprising:a delivery chamber located within the fuel injector assembly; a gas supply means for supplying gas; a mass flow rate control means for controlling the mass flow rate of fuel and gas supplied to the delivery chamber, the mass flow rate being a function of a differential pressure across the mass flow rate control means, wherein the mass flow rate control means includes at least a gas mass flow rate control means, the gas mass flow rate control means being a gas orifice located in the gas supply means; and valve means for selectively communicating the delivery chamber to the engine to deliver fuel to the engine, wherein when the valve means is opened, at least compressed gas is caused to flow thereby generating a differential pressure across the mass flow rate control means such that a controlled fuel flow is provided to the engine.
