Abstract
A fuel injector assembly for an internal combustion engine, including: a delivery chamber (5) located within the injector assembly (1); a mass flow rate control means (50) for controlling the mass flow rate of fuel and compressed gas supplied to the delivery chamber (5), the mass flow rate being a function of the differential pressure across the mass flow rate control means (50); and valve means (9) for selectively communicating the delivery chamber (5) to the engine to deliver fuel to the engine; wherein when the valve means (9) 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.
