Abstract

An intake system assembly including an intake manifold including a housing defining an interior conduit in fluidic communication with an intake valve and a lattice structure extending from an outer surface of the housing. The lattice structure includes a plurality of intersecting walls and the lattice structure and the housing form a continuous piece of material.

First claim

The invention claimed is:

1. An intake system assembly, comprising:
an intake manifold including a housing defining an interior conduit in fluidic communication with an intake valve; and
a lattice structure extending from an outer surface of the housing;
where the lattice structure includes a plurality of intersecting walls and a plurality of airflow channels are formed between the plurality of intersecting walls and extend between two opposing sides of the lattice structure; and
where the lattice structure and the housing form a continuous piece of material.

2. The intake system assembly of claim 1 , where the intake manifold includes a first section and a second section and the lattice structure extends between the first and second sections.

3. The intake system assembly of claim 2 , where the first section is in fluidic communication with a first cylinder bank and the second section is in fluidic communication with a second cylinder bank.

4. The intake system assembly of claim 1 , further comprising a flow diverter coupled to the housing and directing airflow into the lattice structure.

5. The intake system assembly of claim 4 , where the flow diverter is arranged at a non-perpendicular angle with regard to the outer surface of the housing.

6. The intake system assembly of claim 1 , where the lattice structure is positioned external to an engine compartment.

7. The intake system assembly of claim 1 , where the lattice structure and the housing are constructed out of an equivalent material.

8. The intake system assembly of claim 7 , where the equivalent material is aluminum.

9. The intake system assembly of claim 1 , where the intake manifold and the lattice structure are cooperatively constructed using additive manufacturing.

10. A method for manufacturing an intake system assembly, comprising:
printing a plurality of layers of metal to form the intake system assembly including an intake manifold and a lattice structure forming a continuous shape;
where the intake manifold includes a housing defining an interior conduit in fluidic communication with an intake valve;
where the lattice structure extends from an outer surface of the housing; and
where the lattice structure includes a plurality of intersecting walls and a plurality of airflow channels are formed between the plurality of intersecting walls and extend between two opposing sides of the lattice structure.

11. The method of claim 10 , where the plurality of layers of metal are layers of aluminum.

12. The method of claim 10 , where printing the plurality of layers of metal includes implementing a direct laser metal sintering process.

13. The method of claim 10 , where the lattice structure is positioned external to an engine compartment.

14. The method of claim 10 , where the intake manifold includes a first section and a second section and where the lattice structure extends between the first and second sections.

15. An intake system assembly, comprising:
an additively manufactured intake manifold and a lattice structure forming a continuous shape;
where the additively manufactured intake manifold includes a housing defining an interior conduit in fluidic communication with a plurality of intake runners providing intake air to a plurality of intake valves;
where the lattice structure extends from an outer surface of the housing; and
where the lattice structure includes a plurality of intersecting walls defining a plurality of airflow channels positioned between the plurality of intersecting walls.

16. The intake system assembly of claim 15 , where the additively manufactured intake manifold includes a first section and a second section and the lattice structure extends there between and where the first section is in fluidic communication with a first cylinder bank and the second section is in fluidic communication with a second cylinder bank.

17. The intake system assembly of claim 16 , where the lattice structure is positioned external to an engine compartment and where the engine compartment at least partially encloses the first cylinder bank and the second cylinder bank.

18. The intake system assembly of claim 15 , where the housing of the additively manufactured intake manifold and the lattice structure are constructed out of aluminum.

19. The intake system assembly of claim 15 , further comprising a flow diverter coupled to the housing and directing airflow into the lattice structure and where the flow diverter is arranged at a non-perpendicular angle with regard to the outer surface of the housing.

20. The intake system assembly of claim 15 , where the plurality of intersecting walls in the lattice structure includes a first wall intersecting a second wall at an angle between 30 and 60 degrees.
