Abstract
A fuel rail for a non-return fuel injection system and a method of breaking-up pressure pulsations in the fuel rail. The fuel rail comprises an inlet, at least one first outlet, and a first tube providing fluid communication between the inlet and the at least one outlet. The inlet is adapted for fluid communication with a source of pressurized fuel. Each at least one first outlet is adapted for fluid communication with a respective fuel injector. The first tube extends along a first axis and includes a first portion and a second portion. The first portion extends a first length along the first axis and has a first cross-sectional shape transverse to the first axis. The second portion extends a second length along the first axis and has a second cross-sectional shape transverse to the first axis. The second cross-sectional shape has a first indentation toward the first axis, and the first indentation disrupts pressure pulsations propagating through the first tube.
