Embodiment Construction

[0052] figure 1 and figure 2 A fuel supply device 10 for an internal combustion engine, in particular a direct injection gasoline or diesel engine, is shown. The fuel supply device 10 comprises a fuel distribution pipe 12 which extends in a longitudinal direction according to a direction arrow 14 . An elongated receiving chamber 16 is formed by the fuel distribution pipe 12 , in which fuel for the internal combustion engine under very high pressure can be received. To this end, fuel is conveyed from the fuel tank by means of at least one pump device, placed under high pressure and conveyed via the connecting piece 18 into the receiving chamber 16 of the fuel distribution line 12 .

[0053] An at least substantially circular connection opening 24 is formed on the side 20 of the jacket surface 22 of the fuel rail 12 , through which fuel under high pressure can be discharged from the receiving chamber 16 . In addition, a valve box 26 is arranged on the side 20 , which is in f...

Abstract

The invention relates to a fastening arrangement (11) of a fuel supply device (10) on an internal combustion engine, and also relates to a method for fastening the fuel supply device (10) of said type to the internal combustion engine. In the fastening arrangement (11), at least one fuel distributing element (12) which runs along a longitudinal direction (14) and which has at least two connection openings (24) for connecting a respective fuel injection device is fastened to the internal combustion engine by means of at least one connecting part (36, 36'), wherein the connecting part (36, 36') is connected to the fuel distributing element (12) via a holding part (30, 30') which has a receptacle (32, 32') which completely surrounds at least one outer circumferential region of the fuel distributing element (12) and in which at least one portion of the fuel distributing element (12) is held, and wherein a point (62, 62'), which is situated in an elongation of the connecting element (36, 36') in a direction of extent (38, 38'), of the fuel distributing element (12) lies on a straight line (64) which connects the two connection openings (24).

Description

technical field [0001] The invention relates to a fastening device of a fuel supply device on an internal combustion engine according to the preamble of claim 1 and a method for fastening a fuel supply device to an internal combustion engine according to the preamble of claim 13 . Background technique [0002] WO 2006 / 105388 A1 discloses a fuel distribution pipe having an elongated tubular body with a wall by which a hollow chamber is delimited. The elongated tubular body is constructed of a thermoset composite material. The fuel distribution tube includes a pressure connector having a hollow chamber that is fluidly connected to the hollow chamber of the elongated tubular body. Furthermore, the fuel distribution pipe can have a layer by which the elongated tubular body is injection-moulded and which completely surrounds at least one outer circumferential region of the elongated tubular body. The connecting element is then connected to the injection-molded layer, via which ...
