Abstract
Abstract @ A compact central fuel rail (16) supports injectors (18) which deliver fuel to both banks of a V-engine. Each injector (18) is clipped into place in a respective socket (28) in the fuel rail (16), and the fuel rail is held in place by bolts (72) applying a downward force to the fuel rail (16). The fuel rail (16) is extruded with both fuel supply (24) and fuel return passages (26), a single circular plug (40) provides a closure for the associated ends of the passages (24, 26), and a plug (70) in the return passage (26) limits interconnection of the passages (24, 26).

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
201 words
A compact fuel rail (16) for a V-engine having a plurality of fuel injector openings (20) arranged in two lines, said fuel rail comprising an elongated body (22) mountable above and between said lines and having a plurality of axially spaced fuel injector sockets (28), some-of said sockets extending transversely leftwardly and downwardly toward one of said lines and the remainder of said sockets extending transversely rightwardly and downwardly toward the other of said lines, said body (16) further having an axially extending fuel passage (24) intersecting said sockets (28) for supplying fuel to said sockets, each of said sockets (28) being adapted to receive a fuel injector (18) suitable for delivering fuel from its socket through one of said openings(20), characterised in that each of said injectors (18)has a clip (32) for securing said injector to said fuel rail (16), each of said injectors further has a tip(36) adapted to be received in one of said openings, and there are means (72) for securing said fuel rail (16) to said engine above and between said lines by exerting only a downward force on said body (22) to thereby retain said injectors (28) between said fuel rail (16) and the engine.
Claim 2
Dependent Claim
201 words
A compact fuel rail (16) for a V-engine having a plurality of fuel injector openings (20) arranged in two lines, said fuel rail comprising an elongated body (22) mountable above and between said lines and having a plurality of axially spaced fuel injector sockets (28), some-of said sockets extending transversely leftwardly and downwardly toward one of said lines and the remainder of said sockets extending transversely rightwardly and downwardly toward the other of said lines, said body (16) further having an axially extending fuel passage (24) intersecting said sockets (28) for supplying fuel to said sockets, each of said sockets (28) being adapted to receive a fuel injector (18) suitable for delivering fuel from its socket through one of said openings(20), characterised in that each of said injectors (18)has a clip (32) for securing said injector to said fuel rail (16), each of said injectors further has a tip(36) adapted to be received in one of said openings, and there are means (72) for securing said fuel rail (16) to said engine above and between said lines by exerting only a downward force on said body (22) to thereby retain said injectors (28) between said fuel rail (16) and the engine.
Claim 3
Dependent Claim
133 words
A compact fuel rail according to claim 1, in which the elongated body (22) of said fuel rail (16) has a second axially extending fuel passage (20) alongside said fuel passage, and said fuel passages (24, 26) are interconnected, characterised in that at least one end of said body (22) has a circular recess (42) intersected by and encompassing the associated ends of said fuel passages (24, 26), one of said passages (26) is circular in cross section, a circular plug (70) is received in said circular cross section passage (26) adjacent said recess (42) for limiting interconnection of said passages (24, 26) through said recess (42), and a circular plug (44) is received in and seals said recess (42) to provide a closure for the associated ends of said passages (24, 26).
