Abstract
A fuel rail is provided which includes a housing formed by a first member with a first thickness. A bracket is provided, connected to the first member to connect the fuel rail to an internal combustion engine. A second stamped member is provided and is sealably connected to the first member to form a control volume therewith. The second member has a second thickness that is materially lower than the first thickness. Accordingly, the second member has a wall to damp pulsations caused by the opening and closing of the injectors fluidly connected with the rail.
Claims13
A fuel rail for delivering fuel to a plurality of fuel injectors for a reciprocating piston internal combustion engine, comprising:
- a sealed housing including a first stamped metallic member having a first thickness, said first member having at least first and second injector outlets for delivering fuel to said fuel injectors;
- injector cups fixably connected with said first member adjacent said injector outlets;
- and
- a second stamped metallic member sealably connected to said first member forming a control volume therewith, said second member having a second thickness materially thinner than said first thickness to damp pulsations caused by opening and closing of fuel injectors connected to said injector cups.
A fuel rail for delivering fuel to a plurality of fuel injectors for a reciprocating piston internal combustion engine comprising:
- a sealed housing having an inlet for receiving fuel, said housing including:
- a first stamped male metallic member having a first thickness between 0.030 and 0.045 inches, said first member having at least first and second injector outlets for delivering fuel to said fuel injectors;
- injector cups fixably connected with said first member adjacent said injector outlets;
- a bracket fixably connected to said first member for connecting said fuel rail to said internal combustion engine;
- and
- a second stamped female metallic member sealably connected to said first member with legs overlapping legs of said first member, and forming a control volume therewith, said second stamped member having a second thickness materially lower than said first thickness between 0.010 and 0.030 inches to damp pulsations caused by opening and closing of said injectors.
