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 positive crankcase ventilation (PCV) apparatus. The gooseneck conduit transitions into the channels and runners such that there is no seal between the gooseneck, plenum, and runners.
Claims20
An engine system comprising:
- a cylinder head;
- and
- a layered intake manifold defining
- runners each having a gas outlet leading to the cylinder head, and
- a plenum including partial walls forming channels radiating from a common gas inlet that extends into a conduit, the conduit having an integrated positive crankcase ventilation (PCV) apparatus and transitioning into the channels and runners such that there is no seal between the conduit, plenum, and runners.
2 more elements
An engine component comprising:
- stratified layers defining an intake manifold having runners each including a gas outlet leading to a cylinder head, and a plenum including partial walls forming channels radiating from a common gas inlet, the gas inlet extending outwardly into a conduit having an incorporated exhaust gas recirculation (EGR) apparatus, the conduit gradually transitioning into the channels and runners without a seal, and the partial walls forming endoskeletal structure configured to support the intake manifold.
A method comprising:
- forming, by additive manufacturing, an internal combustion engine intake manifold of stratified layers that define runners each having a gas outlet leading to a cylinder head, and a plenum including partial walls that form channels radiating from a common gas inlet that extends outwardly into a gooseneck conduit having an incorporated positive crankcase ventilation (PCV) apparatus, exhaust gas recirculation (EGR) apparatus, or both, the gooseneck conduit transitioning into the channels and runners such that there is no seal between the gooseneck, plenum, and runners, the partial walls forming endoskeletal structure configured to support the intake manifold.
