Coaxial flow through fuel rail with a damper for a recirculating fuel system |
摘要 |
A fuel rail has a high pressure inlet and a low pressure outlet. The high pressure inlet feeds pressurized fuel to a plurality of injectors along the fuel rail. A fuel return line, which is connected with the low pressure outlet, is positioned substantially centrally of and coaxial with the fuel rail. The fuel return line is non-circular in configuration having a width to height ratio greater than one. The configuration of the return fuel line and the flexibility of the walls thereof provide a damper that reduces the pressure pulsations in the high pressure fuel.
