Abstract

An engine component includes a tubular member, of stratified layers, curved on both ends and comprising outwardly protruded nozzles located on one side. Each of the nozzles comprising an elongated body and a tip defining apertures. The tubular member forms a nitrous oxide delivery apparatus configured to increase an internal combustion engine's power output and is located in a cavity of an intake manifold such that there is no seal between the member and the manifold.

First claim

What is claimed is:

1. An engine component comprising: a tubular member, of stratified layers, curved on both ends and comprising outwardly protruded nozzles located on one side, each of the nozzles comprising an elongated body and a tip defining apertures, the tubular member forming a nitrous oxide delivery apparatus configured to increase engine power output and located in a cavity of an intake manifold such that there is no seal between the tubular member and the intake manifold, wherein the tubular member is located adjacent to a bellmouth opening of an intake manifold runner, and wherein the tubular member is placed upon a flange within a notch of the bellmouth opening.

2. The component of claim 1 , wherein the tip lies flush with an internal surface of the intake manifold.

3. An engine component comprising: stratified layers defining an integrated intake manifold and a first additive fluid delivery port including a tubular inlet, outside the intake manifold and defining branches extending into an interior of the intake manifold such that there is no seal between the engine component and the manifold, each of the branches extending into wings forming a tubular curvature containing a plurality of nozzles protruding from the curvature into the interior, wherein the tubular curvature is located adjacent to a bellmouth opening of an intake manifold runner, wherein the tubular curvature is placed upon a flange within a notch of the bellmouth opening, and wherein the additive fluid is nitrous oxide.

4. The component of claim 3 , further comprising a second fluid delivery port.

5. The component of claim 4 , wherein the first and second fluid delivery ports supply different fluids to the intake manifold.

6. The component of claim 4 , wherein the first and second fluid delivery ports are arranged at different locations of the intake manifold.

7. The component of claim 4 , wherein the first fluid delivery port has different dimensions than the second fluid delivery port.

8. The component of claim 4 , wherein the first fluid delivery port operates continuously while the second fluid delivery port operates discontinuously.

9. A method comprising: forming, by additive manufacturing, an integrated intake manifold and a fluid delivery apparatus of stratified layers including a conduit based on the exterior of the intake manifold and defining a plurality of branches extending into an interior of the intake manifold such that there is no seal between the apparatus and the manifold, the plurality of branches transitioning into sub-branches each forming a curved tubular portion with nozzles penetrating into the interior, wherein the curved tubular portion is located adjacent to a bellmouth opening of an intake manifold runner, wherein the curved tubular portion is placed upon a flange within a notch of the bellmouth opening, and wherein the additive fluid is nitrous oxide.

10. The method of claim 9 , further comprising forming symmetrical branches.

11. The method of claim 9 , further comprising forming the nozzles to protrude through an intake manifold body.
