Abstract
A fuel rail for a direct injection engine. The fuel rail includes an elongated tubular housing which defines an elongated main chamber. An elongated tube is disposed in the main chamber of the housing and defines an inlet chamber inside of the tube and an annular outlet chamber between the housing and the tube. The tube has a fuel inlet open to its inlet chamber and adapted for connection with a fuel pump. At least two orifices are formed through the tube which fluidly connects the inlet chamber with the outlet chamber. The orifices are positioned and sized to minimize fuel pressure gradients in the fuel rail caused by fuel injection by the fuel injectors.
