Problems solved by technology

[0003] The configuration of the fuel injection system known from DE 10 2005 020 380 A1 has the disadvantage that vibrations can be transmitted between the connection stub and the inlet stub of the fuel injection valve via the wire ring
This leads to a strong noise development on the cylinder head and on the fuel distributor guide plate

Embodiment Construction

[0023] figure 1 A fuel injection system 1 with a suspension 2 is shown in a simplified, schematic sectional illustration according to a first exemplary embodiment. The fuel injection system 1 can be used in particular for high-pressure injection in internal combustion engines. The fuel injection system 1 can be used in particular in hybrid compression external ignition internal combustion engines. The suspension device 2 is particularly suitable for such a fuel injection system 1 .

[0024]The fuel injection system 1 has a fuel guide part 3 which, in the exemplary embodiment, is designed as a fuel distributor guide plate 3 . The fuel distributor guide plate 3 has a tubular base body 4 and a connecting body 5 . An elongated fuel chamber 6 is formed in the tubular base body 4 , from which a connecting channel 7 led by the connecting body 5 branches off. In this case, a further connecting body is preferably attached to the tubular base body 4 , said further connecting body ha...

Abstract

The invention relates to a mounting (2) for fuel injection systems (1), which is used to connect a fuel injection valve (17) to a fuel-guiding component (3), comprising a connecting body (5) and a connecting piece (9) which are interconnected. A receiving chamber (15) is formed inside the connecting body (5) and the connecting piece (9), in which a fuel nozzle (16) of the fuel injection valve (17) is at least partially arranged. The connecting piece (9) comprises an inner collar (12). The invention also relates to an elastically deformable element (27). Said elastically deformable element (27) is at least indirectly supported on the inner collar (18) of the connecting piece (9). Also, the fuel nozzle (16) is supported at least indirectly on the elastically deformable element (27). The invention also relates to a fuel injection system comprising said type of mounting (2).

Description

technical field [0001] The invention relates to a mount for a fuel injection system for connecting a fuel injection valve to a fuel guide component, and to a fuel injection system with such a mount. The invention relates in particular to the field of fuel injection systems for hybrid compression externally ignited internal combustion engines. Background technique [0002] A fuel injection system of this type with acoustic decoupling is known from DE 10 2005 020 380 A1. The known fuel injection system comprises fuel injection valves, receiving bores for the fuel injection valves in the cylinder head and fuel distributor lines with connection stubs. The fuel injection valve is partially introduced into the nipple. In one possible embodiment, the fuel injector has a wire ring in the region of its inlet stub which engages in the groove. Furthermore, a coupling body in the form of a union nut is provided, which is screwed onto an external thread on the circumference of the cou...
