摘要： A fuel injector for an internal combustion engine having an elongated body with a fuel inlet end and a fuel discharge end. The injector body includes an outwardly extending plate attached at a position between its ends and this plate includes at least one radially outwardly extending tab so that the cross-sectional shape of the plate is noncircular. A fuel cup receives the fuel inlet end of the fuel injector and includes a radially inwardly extending ledge at a mid position of the cavity. This ledge includes a through bore complementary in shape to the shape of the plate so that, with the fuel injector and plate aligned at a predetermined angular assembly position, the plate passes through the ledge upon insertion of the fuel injector into the cavity. Thereafter, rotation of the fuel injector and attached plate to a locking position positions the tabs above the ledge thus locking the fuel injector to the fuel cup.

摘要： An internal combustion engine for a motor vehicle includes at least one cylinder, an injection valve associated to the cylinder for direct injection of fuel into a combustion chamber of the cylinder. The injection valve is received in a receiving opening of a cylinder head of the internal combustion engine and held by a support element in the receiving opening. The support element is secured in its rotational position by a formfitting engagement of a first formfit element on the injection valve, and by a formfitting engagement of a second formfit element on the cylinder head. A support element of this type ensures a particularly satisfactory securement of the rotational position of the injection valve. In the event of structural changes to the cylinder head or at the injection valve, it is only necessary to adapt the support element so that such modifications can be realized particularly inexpensively.

摘要： A fuel injector cup assembly (26) includes a fuel injector cup (10) having an opening (18) to receive fuel from a fuel rail (15). An open end (27) receives an inlet of a fuel injector (10) therein such that an O-ring (16) seals with the injector cup. A mounting portion (20) extends from a body (29) of the cup and mounts the cup with respect to a cylinder head. Rotation limiting structure (26) is associated with the mounting portion such that when the cup is coupled to the cylinder head and when a first moment is created about the mounting portion causing rotation of the cup with respect to the fuel injector, the rotation limiting structure will engage at least the mounting portion of the cup and create a second moment equal and opposite to the first moment, to prevent further rotation of the cup.

摘要： A covering body (10) made of a synthetic resin and including a rear shoulder part (16) oriented toward a fuel inlet part (6) side is formed around an outer periphery of an intermediate portion in an axial direction of a fuel injection valve (I). The rear shoulder part (16) includes: a first semicircular shoulder part (16a) extending over a half periphery of the covering body (10); a second semicircular shoulder part (16b) shifted in the axial direction with respect to the first semicircular shoulder part (16a) and extending over the other half periphery of the covering body (10); and a standing wall (16c) standing to connect the first and second semicircular shoulder parts (16a, 16b). On a front end of a fuel supply cap (20), a semicircular holding surface (28b) holding at least one of the first and second semicircular shoulder parts (16a, 16b) to prevent the fuel injection valve (I) from being fallen off from the mounting hole (2), and a rotation stopper surface (28c) abutting against the standing wall (16c) to prevent rotation of the fuel injection valve (I) are formed. Accordingly, it is possible to provide a fuel injection valve mounting structure including positioning means capable of firmly restricting an orientation of a coupler in a given direction without forming projections on a fuel injection valve and a fuel supply cap.

摘要： A nested fuel injector that includes an injector housing having a bore longitudinally therethrough, and a pintle assembled to the housing and positioned substantially within the bore. The pintle has a head located at an end of a cylindrical portion, wherein the head is seated in one end of the bore, and the seating of the head defines a variable-area exit orifice. A wave spring is assembled onto the pintle and configured to urge the pintle into the seating position. The bore is configured for the passage of a pressurized flow of fuel. The fuel pressure urges the pintle head away from the exit orifice to permit the pressurized fuel to flow from the bore out through the exit orifice.
