Abstract: A method for producing fuel rails, which contain a hollow chamber that communicates with a fuel source via a connection. The fuel rail supplies fuel to a number of injection valves. At least one preassembled unit of an injection valve is integrated into the fuel rail by means of a materially adhesive connection during the production of the fuel rail and an electrical contacting of the individual injection valves is produced at the same time.

Abstract: An intake tract for an internal combustion engine, including a number of divided intake line sections corresponding to the number of cylinders in the internal combustion engine. These intake line sections are mountable on the internal combustion engine in the intake area. A fuel distributor and at least one injector supply fuel to the combustion chambers of the internal combustion engine. At least one injector unit, the mounting locations thereof as well as fuel supply components and their contacting elements are integrated into a cover element to be joined to a lower-shell-shaped intake manifold section.

Abstract: A device for supplying fuel to combustion chambers of an internal combustion engine is described. An injector (2), which is supplied with fuel through a fuel line (10), is accommodated in a receptacle (34) in the receiving body (1) of an internal combustion engine. The injector (2) is positioned in the receiving body (1) by using a hold down (9), the hold down (9) having areas (12, 18, 19) for receiving electric contact elements (13, 14, 16).

Abstract: The present invention relates to a distributor device (1) for fuel injection systems of internal combustion engines for supplying gas and for electrical contacting of fuel injection valves (2).The distributor device has a gas supply line (70) for the joint gas supply to the fuel injection valves (2), comprising a supply orifice (71) and a number of connecting parts (7) for connecting the supply orifice (71) to gas inlet channels (13) of the fuel injection valves (2). Furthermore, a plurality of bushings (78) are provided along the gas supply line (70) and work together with plugs (47) provided on the fuel injection valves (2) to establish electric contact with the fuel injection valves (2).In the refinement according to this invention, a locking spring (88) is provided for each bushing (78) to lock the connection of the bushing (78) to the plug (47) of the respective fuel injection valve (2).

Abstract: A fuel injection system includes a substantial integration of various components, the fuel injection system including at least one fuel injector and at least one intake manifold, as well as a fuel supply channel, which are all surrounded by a plastic sheathing. The full integration of the fuel injectors into an induction pipe component made of plastic leads to the reduction or elimination of both electrical and hydraulic interfaces. Thus, only a compact component remains that is very simple to attach to a cylinder head of an internal combustion engine. Means for electrically contacting the fuel injectors (1), such as connector sockets, are also fully integrated in the plastic sheathing. This fuel injection system is especially suited for use in mixture-compressing internal combustion engines having externally supplied ignition.

Abstract: The invention joins the intake module or intake tube to the engine with the aid of a displaceable retaining element. The retaining element, which in the mounted state is under initial tension, is braced against an engine retention face associated with the engine and against at least one counterpart intake module retention face joined to the intake module or intake tube. Because of the displaceability of the retaining element, the expense and effort of mounting and dismantling the intake module or intake tube to the engine by screws are substantially reduced. The engine is intended in particular for motor vehicles.

Abstract: A device for attaching and securing a valve is particularly suited for fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition. The device provides a twistable holding-down clamp which, together with an inner pressure element, prevents a fuel-injection valve from slipping and which, together with an outer fixing ring as a part of a bayonet catch, whose corresponding bayonet locking bars are constructed on the fuel distributor, ensures a simple and reliable attachment to the fuel distributor. The holding-down clamp is sealed by the sealing cap, which is set down on the holding-down clamp and through which the connecting cables also run. The fuel-injection valve does not have any functional elements for attaching in the valve-mount opening of the fuel distributor.

Abstract: A fuel distributor, including a plug connection which serves to provide electrical contact for the fuel injection valves comprising a socket and a plug. The plug connection that is located directly on the valve connection neck, in a region between two sealing elements, that seal off a connection between the fuel distributor and the fuel injection valve, so that the fuel-carrying region is sealed off from the guide conduit, which in turn is sealed off from external influences such as splashing water. Thus, even the plug connections located in the region of the guide conduit are protected. The fuel distributor is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
