Abstract
An integrated fuel delivery module for a fuel injected engine includes a fuel rail having a fuel distribution channel and a plurality of spaced-apart fuel injector sockets connected with the fuel distribution channel. A high-pressure fuel pump has a high-pressure chamber connected internally to the fuel distribution channel without external high-pressure fuel lines.
Claims17
An integrated high-pressure fuel delivery module, comprising:
- a one piece integral unit including an intake manifold part having a plurality of intake ports configured to flow air to a cylinder head, and a fuel rail having a fuel distribution channel and a plurality of space-apart fuel injector sockets connected with said fuel distribution channel;
- said one piece integral unit further including a pump housing and a high-pressure fuel pump having a high-pressure chamber connected internally to said fuel distribution channel without external high-pressure fuel lines.
An integrated high-pressure fuel delivery module for connection to a high-pressure fuel pump having a high-pressure chamber connected internally to said fuel distribution channel without external high-pressure fuel lines for an engine,
- said fuel delivery module comprising a fuel rail having a fuel distribution channel and a plurality of spaced-apart fuel injector sockets connected with said fuel distribution channel;
- and wherein said fuel pump includes a follower adapted to connect a cam lobe to actuate said fuel pump.
An internal combustion engine of the type having a plurality of combustion chambers and an intake system supplying air to said combustion chambers, said intake system comprising:
- an intake manifold part including a plurality of intake ports configured to supply air to the combustion chambers;
- a plurality of fuel injectors supplying fuel directly to said combustion chambers;
- a fuel rail extending along said intake manifold and formed integrally therewith, said fuel rail including a fuel distribution channel supplying fuel to said fuel injectors;
- and
- a fuel pump mounted to said fuel rail and having a fuel pump housing formed integrally with said fuel rail, said fuel pump having a high-pressure chamber connected internally to said fuel distribution channel without external fuel lines.
An integrated fuel delivery module for a fuel injected engine, comprising:
- an intake manifold part having a plurality of intake ports configured to supply air to combustion chambers of an internal combustion engine;
- a fuel rail formed integrally with said intake manifold part and having an elongated fuel distribution channel and a plurality of spaced-apart fuel injection sockets connected to said fuel distribution channel;
- and
- a fuel pump having a high-pressure chamber connected internally to said fuel distribution channel, said fuel pump including a housing, at least a portion of which is integrally formed with said fuel rail.
An integrated fuel pump and fuel rail for a fuel injected engine, comprising:
- a fuel rail having an elongated fuel distribution channel and a plurality of spaced-apart fuel injection sockets connected to said fuel distribution channel;
- and
- a fuel pump having a high-pressure chamber connected internally to said fuel distribution channel, said fuel pump including a housing, at least a portion of which is integrally formed with said fuel rail, said fuel pump including a follower adapted to contact a cam lobe to actuate said fuel pump.
