Abstract
A fuel metering and injection system for an internal combustion engine circulates fuel through a metering chamber (11) via valved fuel inlet and fuel outlet ports (25, 26) to prepare a metered quantity of fuel. Compressed gas is introduced into the metering chamber through a valved air inlet port (14) to displace the metered fuel and deliver it to the engine. Phasing of the valves is controlled to ensure that the fuel inlet and outlet valves (60, 61) are closed prior to opening of the air inlet valve (16), and that on completion of the injection phase residual gas in the metering chamber (11) is expelled through the fuel outlet port (26).
