Abstract
Abstract A fuel rail for a fuel injected engine is located directly above the engine and is formed by passages (17) in spacers (10,12,14) which space an air plenum (24) from the intake manifold (26). The rail has at least one main fuel passage (17) which is straight and on which fuel injector cups (28) are directly mounted with direct communication from the cups to the passage.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
73 words
A fuel rail for a V-configuration engine, the rail comprising a spacer body adapted to be located between an air plenum and the inlet manifold of the engine and having air passages therethrough to connect the plenum and the manifold, at least. one longitudinal bore which defines a fuel passage extending through the spacer body, and a plurality of fuel injector cups projecting from the spacer body and communicating with the fuel passage.
Claim 2
Dependent Claim
73 words
A fuel rail for a V-configuration engine, the rail comprising a spacer body adapted to be located between an air plenum and the inlet manifold of the engine and having air passages therethrough to connect the plenum and the manifold, at least. one longitudinal bore which defines a fuel passage extending through the spacer body, and a plurality of fuel injector cups projecting from the spacer body and communicating with the fuel passage.
Claim 3
Dependent Claim
33 words
A fuel rail as claimed in Claim 1, wherein the spacer body comprises a number of separate spacer members joined together by a rail member or members through which the fuel passage runs.
Claim 4
Dependent Claim
41 words
A fuel rail as claimed in any Claim 1 or Claim 2, wherein the rail member forms a dividing wall in the air passage through each spacer member, so that the separation between the air passages from the plenum is maintained.
Claim 5
Dependent Claim
59 words
A fuel rail as claimed in any preceding Claim for an engine which has centrally located air inlet tracts, wherein a single longitudinal bore is positioned centrally above the engine to provide the fuel passage so that it is possible to use a single, straight passage to serve the cups for the injectors on both banks of the engine.
Claim 6
Dependent Claim
38 words
A fuel rail as claimed in Claim 1 or Claim 3, wherein there are two parallel longitudinal bores, connected by cross drillings at each end, so that two rows of injectors can be served by the one rail.
Claim 7
Dependent Claim
27 words
A fuel rail as claimed in any preceding claim, which is manufactured as an aluminium stamping with subsequent machining to define the internal contours of the cups.
