    摘要: It is an object of the present invention to achieve the improvement of the combustion efficiency in the combustion chamber and the improvement of the fuel consumption rate by forming, in the inner circumferential surface of a sleeve into which a projection provided at an inlet valve rod is slidably fitted, fuel gas injection holes situated within the movement region of the projection of the inlet valve rod and opened and closed with the movement of the inlet valve rod, such that the fuel gas injection holes are each formed in an ellipse, to thereby lengthen the injection period of the fuel gas injected into an inlet path and promote mixing with the supply air through the inlet path. There is provided a fuel gas supply device for a gas engine in which a fuel gas flows along the axial direction on the outer circumferential side of an inlet valve rod (4), and is supplied to an inlet path (2) in a cylinder head (1). The device is characterized in that fuel gas injection holes (6a) to be opened and closed with the movement of a projection (5) are provided in the inner circumferential surface of a sleeve (6) into which the projection (5) is slidably fitted, the projection (5) being provided at the inlet valve rod (4), having a larger outer diameter than the inlet valve rod (4) and having a portion concentric with and in parallel with the inlet valve rod (4), and in that the fuel gas injection holes (6a) are each formed in an ellipse, and the opening upper and lower end region part of the ellipse is situated within the movement region of the projection (5).

    摘要: A fuel injector for an engine includes a fuel volume (24) having an air inlet port (30) having a porous membrane (38). The membrane (38) is permeable to air and impermeable to fuel whereby air inlet to the fuel volume (24) forms a two-phase air bubble/fuel dispersion within the fuel volume (24). Upon actuation of the needle valve (18) of the injector, this two-phase air bubble/fuel dispersion flows through the orifice (28) into the engine whereby improved atomization, burn and fuel economy with resultant reduction in emissions are provided.

    摘要: [Object]
    To provide a technique for further improving fuel economy.
    [Solution]
    An intake port 24 has a quadrangular port region that is substantially quadrangular in a cross section perpendicular to a longitudinal direction (flowing direction of intake air), and openings of injector attachment holes 26 to branch ports 24b and 24c are nearly entirely provided in upper flat wall portions 122b and 122c in quadrangular port regions of the branch ports 24b and 24c. Thus, the size of a dead volume 92 can be made smaller than when the injector attachment holes are provided in an intake port of circular cross section. Therefore, turbulence of intake air flowing in the intake port 24, particularly in the branch ports 24b and 24c can be suppressed, and mixability of fuel and intake air can be enhanced to improve combustion efficiency. As a result, fuel economy can be improved further.

    摘要: A flow-control assembly may include a fluid conduit and a flow-control valve in the fluid conduit. The flow-control assembly may further include a fluid expansion conduit with an inlet defined at least in part by the fluid conduit and configured to selectively receive flow of a fluid from the fluid conduit. The fluid expansion conduit may further include an outlet in fluid communication with the fluid conduit downstream of the flow- control valve. A rotating fluid expander in the fluid expansion conduit may be configured to expand the fluid and thereby rotate and in some embodiments generate electricity. In a first position flow is substantially blocked. In a second position flow is allowed through the fluid expansion conduit. In a third position flow through the fluid conduit is allowed without necessarily passing through the fluid expansion conduit.

    摘要: The fuel and air supply system of the present invention provides fuel from a fuel pump (42) at a first pressure upstream of a pressure reducer (46), fuel being provided directly to the fuel injector (10) at a reduced pressure on the downstream side of the pressure reducer (46). A bypass line (34) in communication with the fuel line (44) upstream of the pressure reducer (46) provides fuel to an air reservoir (50) at the first pressure. The air reservoir (50) lies in communication with a porous member(s) (30) in the fuel injector (10) in an air inlet (32) to a fuel volume (24) within the injector (10). Upon flow of fuel into the air reservoir (50) and closure of normally open fuel and air valves (58,60) in the reservoir (50), air at the first pressure is supplied the porous member(s) (30), creating a pressure differential across the member(s) (30), causing air to flow through the porous member(s) (30) to form air bubbles in the fuel volume (24) for two-phase flow through the fuel injector orifice (28). The air flows for a predetermined time until the reservoir (50) fills with fuel which precludes further air flow into the injector (10). Upon shutdown of the engine, the valves (58,60) in the air reservoir (50) open, draining the fuel from the air reservoir (50) and enabling air at atmospheric pressure to enter the reservoir (50), returning the system for reuse upon engine startup.
