Abstract
An intake system for an engine includes: an intake manifold including a plurality of ports; a cover mounted to the intake manifold over the plurality of ports; a fluid distribution track defined by the cover, the fluid distribution track including a plurality of openings in fluid communication with an interior of the intake manifold by way of the plurality of ports of the intake manifold; and a dampening material between the cover and the intake manifold, the dampening material configured to dampen at least one of noise, vibration, and harshness.
Claims18
An intake system for an engine, the intake system comprising:
- an intake manifold including a plurality of ports;
- a cover mounted to the intake manifold over the plurality of ports;
- a fluid distribution track defined by the cover, the fluid distribution track including a plurality of openings in fluid communication with an interior of the intake manifold by way of the plurality of ports of the intake manifold;
- a cap mounted over the fluid distribution track;
- wherein an air core is defined between the cap and the fluid distribution track;
- and a dampening material between the cover and the intake manifold, the dampening material is configured to dampen at least one of noise, vibration, and harshness.
An intake system for an engine, the intake system comprising:
- an intake manifold including a plurality of columns extending outward from an outer surface of the intake manifold, the plurality of columns defining a plurality of ports;
- a cover welded to the intake manifold by welds at an outer periphery of the cover;
- a fluid distribution track defined at an exterior of the cover, the fluid distribution track including a plurality of openings in fluid communication with an interior of the intake manifold by way of the plurality of ports of the intake manifold, the plurality of ports of the intake manifold are vertically aligned with the plurality of openings of the fluid distribution track;
- a cap mounted to the cover over the fluid distribution track, an air core is defined between the cap and the fluid distribution track;
- and
- a dampening foam between the cover and the intake manifold, the dampening foam configured to dampen at least one of noise, vibration, and harshness.
An intake system for an engine, the intake system comprising:
- an intake manifold including a plurality of columns extending outward from an outer surface of the intake manifold, the plurality of columns defining a plurality of ports, an inner surface of the intake manifold includes runners configured to distribute fluid entering the intake manifold through the plurality of ports;
- a cover welded to the intake manifold by vibration welds at an outer periphery of the cover and between the cover and the plurality of columns;
- a fluid distribution track defined by the cover, the fluid distribution track including a plurality of openings in fluid communication with an interior of the intake manifold by way of the plurality of ports of the intake manifold, the plurality of ports are vertically aligned with the plurality of openings;
- a cap vibration welded to the cover over the fluid distribution track, an air core is defined between the cap and the fluid distribution track;
- and
- a dampening foam between the cover and the intake manifold, the dampening foam is configured to dampen at least one of noise, vibration, and harshness, the dampening foam defines a plurality of apertures, each one of the plurality of apertures receives, and wraps around, one of the plurality of columns.
