ABSTRACT:
A method of fuel injection for an internal combustion engine having one or more combustion chambers and wherein a metered individual quantity of fuel entrained in a gas charge is injected individually by the pressure of the gas directly into each combustion chamber each combustion cycle thereof. The method including the steps of delivering gas from at least one combustion chamber of the engine to a common gas reservoir, and controlling said delivery of gas to the gas reservoir to substantially maintain the gas therein at a pressure above the maximum compression pressure in the combustion chamber prior to commencement of combustion in said combustion chamber. Supplying gas at a regulated pressure from said gas reservoir to receive the metered quantity of fuel and effect in sequence delivery of that fuel into the respective combustion chambers of the engine.
