ABSTRACT:
A fuel injection system incorporates a plurality of fuel injection arrangements, wherein each fuel injection is associated with a particular cylinder of the engine. Each of the fuel injection arrangements comprises a fluid passageway in which fuel and air are combined prior to injection into a combustion chamber of the cylinder. A valve is moveable with respect to an injection port to allow the pressurized fuel/air mixture to flow from the fluid passageway into the combustion chamber. A fuel injector is used to inject liquid fuel into the fluid passageway to be combined with pressurized air within the passageway. The system has a common air rail and a common fuel rail which are each connected to a plurality of the fuel injection arrangements. Upward movement of a piston within a cylinder is used to pressurize the air within the common air rail. All of the fuel injection arrangements can be used to contribute pressurized air to the common air rail.
