Problems solved by technology

However, intense heating occurs due to welding, which changes the shape and / or mutual position of the parts to an undesired extent
This deformation of the components complicates the installation of the injector into the cylinder head which allows only minimal changes in the shape and / or position of the injector due to pre-specified tight tolerances
Therefore, often when installing the injector or the structural unit, such great stresses arise that the injector no longer works completely effectively

Embodiment Construction

[0035] figure 1A structural unit 100 of a fuel system for an internal combustion engine, in particular a direct injection internal combustion engine, is shown in a schematic diagram. The structural unit 100 is preassembled as a module and preferably tested for tightness. The structural unit 100 is thus ready as a ready module for final installation on an internal combustion engine (not shown).

[0036] The structural unit 100 has four fuel-injecting injectors 1 which are each held by a holder 2 . In this case, the number of injectors depends on the design of the internal combustion engine. Constructional units with one, two, three or even more than four injectors are therefore also conceivable.

[0037] The structural unit 100 also has fuel lines 3 , which are each connected at one end to the carrier 2 and at the other end to the fuel distributor 4 . The fuel lines 4 are preferably inserted into the associated holder 2 with a friction fit, so that the fuel lines 4 are each...

Abstract

The present invention relates to a component units (100, 100') for a fuel system of an internal combustion engine, in particular for use in an internal combustion engine having direct injection, having at least one injector (1) which injects fuel, and / or at least one mounting (2), on which at least one injector (1), which injects fuel, is fixable, and having at least one fuel line (3), using which the injector (1) or the mounting (2) is connectable to a fuel distributor (4). It is provided that the injector (1) or the mounting (2) is connected to the fuel line (3) using a plug connection (9). Furthermore, at least one positioning aid is provided, which holds the injector (1) or the mounting (2) in a specified location.

Description

technical field [0001] The invention relates to a fuel system for an internal combustion engine, in particular a structural unit for use in a direct-injection internal combustion engine, with at least one fuel-injecting injector and / or at least one carrier, said at least one fuel-injecting injector It can be fastened to the support and has at least one fuel line by means of which the injector or the support can be connected to the fuel distributor. The invention also relates to an internal combustion engine, in particular for a motor vehicle. Background technique [0002] A structural unit of the type described here usually consists of a plurality of injection valves or injectors for injecting fuel into the combustion chamber of an internal combustion engine or at least consists of a carrier for the injectors and a fuel line by means of which the The injectors are connected with fuel distributors, for example of the distributor pipe type. [0003] Such structural units are...
