Abstract
An assembly for an air assist fuel injection system have a rail configured to fluidly communicate pressurized gas to a fuel pressure regulator and to an air assist fuel injector of the system. The assembly further includes a cover configured to fluidly communicate fuel to the fuel pressure regulator and to a fuel injector of the air assist fuel injection system.
Claims58
An assembly for an air assist fuel injection system, comprising:
- a fuel injector;
- an air assist fuel injector;
- a pressure regulator having a gas reference chamber and a fuel chamber separated by a diaphragm;
- a rail having at least one conduit for supplying pressurized gas for said gas reference chamber and for said air assist fuel injector, a cavity that receives at least a portion of said pressure regulator, and a passageway that receives at least a portion of said fuel injector and that receives at least a portion of said air assist fuel injector;
- and
- a cover that receives at least a portion of said pressure regulator and said fuel injector, said cover including a conduit, for fluidly communicating fuel to said fuel chamber and to said fuel injector.

1 more element
A method, comprising:
- retaining a pressure regulator in a cavity of a rail and a fuel injector in a passageway of the rail by covering the pressure regulator and the fuel injector with a cover configured to communicate fuel to the pressure regulator and the fuel injector, the pressure regulator for maintaining a pressure differential between a fuel supply and a gas supply for an air assist fuel injector.
An assembly, comprising:
- a pressure regulator configured to maintain a pressure differential between a fuel supply and a gas supply, said pressure regulator having a fuel housing defining a fuel chamber and a gas reference chamber housing defining a gas reference chamber,
- a rail configured to receive at least a portion of said gas reference housing and having an internal conduit configured to supply pressurized gas to said pressure regulator;
- and
- a cover attached to said rail and covering said pressure regulator, said cover having a first internal conduit configured to supply fuel to a fuel inlet of said pressure regulator, said cover having a second internal conduit configured to receive fuel from a fuel outlet of said pressure regulator.
1 more element
