Various embodiments may include a long injector for fuel injection comprising: a base portion and an extension portion electrically connected to the base portion. An end of the extension portion may include an electrically conductive terminal with contact clips. The contact clips are spaced at a distance from each other or from a side wall of the electrically conductive terminal. An end of the base portion comprises electrical contacts positioned so each of the electrical contacts can slide into a contact clip of the electrically conductive terminal. The electrically conductive terminal includes a latch mechanism. An electrical connection between the base portion and the extension portion is created when the electrical contacts are inserted into the contact clip and held by the latch mechanism. The long injector further comprises an overmolded body encapsulating the electrical connection between the base portion and the extension portion.

A system, which is used in particular as a fuel injection system for the high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element, which has a supporting surface. The cup has a contact surface on an underside, by way of which the cup is supported at the supporting surface of the holding element by a damping layer. The holding element is attached to the cup. In addition, the fuel injector has a collar, which is braced on the holding element. Because of the damping layer, vibrations are able to be dampened, and the noise transmissions is able to be reduced.

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.

A system, which is used especially as a fuel injection system for the high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element. The holding element has an at least essentially straight first leg and an at least essentially straight second leg. The cup includes at least one recess, which extends through a wall of the cup. The first leg and the second leg are guided through the at least one recess. Furthermore, the connection sleeve of the fuel injector has a collar, which is braced on the first leg of the holding element and on the second leg of the holding element in order to secure the fuel injector on the cup. This makes it possible to fasten the fuel injector on the cup in a reliable manner.
摘要:
A sensor for detecting the properties of the fuel of an internal combustion engine includes at least one pair of internal electrodes (12, 13), extending in an axial direction relative to a further or third external electrode (14) which surrounds them. The invention also relates to a fuel rail (2) to which the sensor may be mounted, and a method for detecting the properties of the fluid.

A coupling device comprises a body in which a passageway is formed which extends from an end aperture of such body to receive a pipe. A collar is positioned partially within the passageway to allow axial translation and has an annular flange outside the end aperture and flexible arms which extend in the passageway. The coupling device further comprises a safety mechanism having a cylindrical portion capable of being fitted on the portion of pipe straddling the end aperture so as to position the cylindrical portion between the pipe and the collar. The safety mechanism also has a safety fork connected to the cylindrical portion and which accommodates positioning of the collar between the body and the annular flange of the collar to inhibit axial movement of the collar towards the body of the device.
