Problems solved by technology
The quality of the brazed joint depends on the extension of the filler material over the entire desired area as it melts in the furnace, and there is a risk of incomplete brazing or no brazing in some areas, which can be caused by insufficient heat transfer to the filler material or Due to the failure of the fill material to extend over the entire intended area

Embodiment Construction
[0035] now refer to Figure 1A , showing a schematic diagram of a portion of a fuel rail assembly for a fuel injection system for an internal combustion engine. The fuel rail assembly 2 has a fuel rail 4 in the form of an elongated substantially tubular body comprising a reservoir for fuel. Fuel is supplied to fuel rail 4 through a fuel inlet by a fuel pump (not shown). The fuel rail 4 has multiple fuel outlets, but for simplicity only one fuel outlet is shown. The fuel outlet has a fuel adapter 6 connected thereto which provides hydraulic communication between the fuel rail 4 and a fuel injector cup 8 having an open lower end 12 where the fuel inlet of the fuel injector (not shown) is located. in the lower end.
[0036] The fuel injector 6 is shaped to adjoin as Figure 1C shown on the outside of the fuel rail 4, Figure 1C showing along Figure 1AThe cross-section of line A-A. In this embodiment the fuel rail is a tubular body and the fuel adapter 6 has an arcuate engag...

The invention relates to a brazed article, comprising a first component (4) and a second component (6) and a brazed joint therebetween to secure the two components (4, 6) together by means of a brazing filler material distributed between a first joining area formed by a surface portion of the first component (4) and second joining area formed by a surface portion of the second component (6), wherein one or both of the joining areas have formed therein at least one elongate slot (14) adapted to contain a brazing material. The first component (4) may comprise a fuel rail of a fuel rail assemblyfor a fuel injection system for an internal combustion engine and the second component (6) may comprise a fuel adapter connecting the fuel rail to a fuel injector or a fixing bracket.
Description
technical field [0001] The present disclosure relates to brazed articles and to methods for producing brazed articles, particularly but not exclusively for components of fuel rail assemblies for internal combustion engines. According to one aspect, the present disclosure thus relates to a fuel rail assembly and to a method for producing a fuel rail assembly, in particular comprising or representing a brazed article. Background technique [0002] Producing a braze joint to join two components involves applying a braze filler material to the parts, bonding the two parts together with the filler material in between, and subjecting the part with the braze filler material to heat in a furnace for melting Brazing filler material. The quality of the brazed joint depends on the extension of the filler material over the entire desired area as it melts in the furnace, and there is a risk of incomplete brazing or no brazing in some areas, which can be caused by insufficient heat trans...
