Embodiment Construction

[0034] figure 1 A high-pressure fuel accumulator 10 for a direct-injection gasoline or diesel engine is shown with a fuel rail 12 . When the Otto or Diesel engine is running, the fuel is pressurized by the high-pressure pump and delivered into the fuel rail 12 , which distributes the fuel to the injectors. The injectors inject fuel into the corresponding cylinders. For this purpose, receptacles 14 , 16 , 18 and 20 of high-pressure fuel accumulator 10 are provided, into which receptacles are each fitted one injector and which can thus be supplied with fuel from fuel rail 12 .

[0035] such as an overview figure 2 and image 3As can be seen, high-pressure fuel accumulator 10 includes sleeves 22 and 24 for connecting high-pressure fuel accumulator 10 to a cylinder head of an Otto or Diesel engine. The sleeve 22 passes completely through the fuel rail 12 , ie is inserted through a corresponding through-opening in the outer surface 26 of the fuel rail 12 and passes through sai...

Abstract

The invention relates to a fuel feed device (10) for fastening to a cylinder head of an internal combustion engine, comprising at least one fuel distributing element (12) extending along a longitudinal direction, and at least one connecting element (22, 24) extending transversely to the longitudinal direction, wherein the connecting element can be used to connect the fuel distributing element (12) to the cylinder head. The fuel feed device (10) comprises at least one reinforcing element (30, 31), which is connected at one side to an outer lateral surface (26) of the fuel distributing element (12) and at the other side to the connecting element (22, 24) outside the fuel distributing element (12).

Description

technical field [0001] The invention relates to a fuel supply device of the type specified in the preamble of claim 1 and a method for producing such a fuel supply device of the type specified in the preamble of claim 9 . Background technique [0002] EP 177260 B1 discloses a device of the stated type for fastening a high-pressure fuel accumulator to a cylinder head, having a high-pressure fuel accumulator with a main line extending along a longitudinal axis. Furthermore, the device comprises a plurality of fluid-tight passages, which are designed to extend completely through the high-pressure fuel accumulator and extend substantially perpendicularly with respect to the longitudinal axis, as well as a plurality of screws, Screws can pass through a corresponding number of fluid-tight passages. In this case, the fastening element can be seated on the cylinder head, whereby the high-pressure fuel accumulator is fastened on the cylinder head. The fluid-tight passage is formed ...
