초록 ▼

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.

[ I claim:] [1.] A fuel injection system, comprising:an engine having a plurality of cylinders;a common air rail;a common fuel rail;a pressure regulator which maintains a generally constant pressure differential between said common air rail and said common fuel rail;a plurality of fuel injection arrangements, each of said plurality of fuel injection arrangements being located at an associated one of said plurality of cylinders, each of said plurality of fuel injection arrangements comprising:a fluid passageway formed within a head of said engine and extending into fluid communication with said associated one of said plurality of cylinders at an injection port, said fluid passageway being in fluid communication with said common air rail;a valve movable between a closed position and an open position with respect to said injection port;a fuel injector disposed in fluid communication with said fluid passageway and with said common fuel rail to cause a preselected quantity of fuel to flow from said common fuel rail to said fluid passageway, said preselected quantity being determined by the pressure within said common fuel rail and the time that said fuel injector permits fuel to flow from said common fuel rail toward said fluid passageway; andwhereby said common air rail and said common fuel rail are both connected in fluid communication with each one of said plurality of fuel injection arrangements, said common air rail being formed within and as an integral part of said head of said engine.
