Abstract
An engine component includes an intake manifold of stratified layers defining a plurality of runners each having a gas outlet leading to a cylinder head, and a plenum including partial walls forming channels radiating from a common gas inlet extending into a gooseneck conduit having an incorporated throttle body. The gooseneck conduit transitions into the channels and runners such that there is no seal between the gooseneck, plenum, and runners.
Claims20
An engine component comprising:
- an intake manifold of stratified layers defining a plurality of runners each having a gas outlet leading to a cylinder head, and a plenum including partial walls forming channels sharing a common gas inlet that extends into a gooseneck conduit, having a throttle body incorporated therewith, such that the gooseneck conduit transitions into the channels and runners without a seal.
An engine system comprising:
- a cylinder head;
- and
- layered material defining an intake manifold having
- a plurality of runners each including a gas outlet communicating with the cylinder head, and
- a plenum including endoskeletal support structure forming channels radiating from a common gas inlet, the gas inlet extending outwardly into a gooseneck conduit that has an incorporated fuel injector and gradually transitions into the channels and runners such that there is no seal between the gooseneck conduit, plenum, and runners.
2 more elements
A method comprising:
- forming, by additive manufacturing, layers of materials defining an internal combustion engine intake manifold having a plurality of runners each including a gas outlet leading to a cylinder head, and a plenum including partial walls that form channels sharing a common gas inlet that extends outwardly into a gooseneck conduit having a fuel injector, a throttle body, or both incorporated therewith, the gooseneck conduit transitioning into the channels and runners such that there is no seal between the gooseneck conduit, plenum, and runners, and the partial walls forming endoskeletal structure configured to support the intake manifold.
