    摘要： A connecting device for fuel injection systems is used for joining a fuel injector to a cup and to a fuel-conveying component. In this context, connecting elements are provided, which are insertable into the cup in such a manner, that they are situated at least approximately in one plane, which is oriented perpendicularly to a longitudinal axis of a cup. Connecting elements take the form of pin-shaped connecting elements. In addition, the connecting elements are formed in such a manner, that they are inserted into the cup, inside an outer cross-section of the cup. A securing element is also provided for securing the connecting elements. Furthermore, a fuel injection system having such a connecting device is provided.

    摘要： A fuel injector may include a housing, a poppet valve assembly, and an actuation assembly. The housing may define a longitudinal bore, a high pressure fuel duct in communication with the longitudinal bore and a valve seat including a valve seat surface and an aperture. The poppet valve assembly may include a stem and a valve head, be disposed within the longitudinal bore and be variably displaceable between a first position and a second position. In the first position, the valve head may abut the valve seat to seal the aperture. In the second position, the valve head may be displaced from the valve seat to open the aperture. The actuation assembly may operate to move the poppet valve assembly between the first position and the second position. The high pressure fuel duct may carry pressurized fuel that biases the poppet valve assembly to be in the first position.

    摘要： The invention relates to an internal combustion engine comprising a cylinder head (1) with a fire deck (7) on the combustion chamber side, at least one injector sleeve (2) detachably connected to the cylinder head (1) for mounting an injection unit, wherein the injector sleeve (2) is screwed to the fire deck (7) on a fire-deck-side first end (5) via a first screw connection (4), and wherein the injector sleeve (2) comprises in the region of the first end (5) at least one radially protruding first bearing area (9) with a first contact face (10) facing the fire deck (10), which contact face rests on a first counter surface (11) formed by the cylinder head (1). In order to increase the rigidity of the cylinder head (1) at low material cost, it is provided that the injector sleeve (2)—preferably in the region of a second end (6) facing away from the first end (5)—comprises at least one radially protruding second bearing area (12) with a second contact face (13) facing the fire deck (7), which contact face rests on a second counter surface (14) formed by the cylinder head (1).

    摘要： An electrical connector assembly of a fuel injector includes a body with external walls defining an internal volume and an internal wall dividing the connector in a first part adapted to be fixed in a complementary engagement with the body of the injector and, in a second part adapted to receive another electrical connector. The electrical connector assembly also includes at least one electrical terminal extending through the internal wall from an inner extremity protruding in the inner volume of the first part of the body, to an outer extremity protruding in the outer volume of the second part of the body. The outer extremity is shaped to receive in a complementary engagement an electrical terminal of said another electrical connector. The connector assembly is adapted to be in fluid communication with the back leak return conduit of the injector.
