Abstract

An engine intake manifold is provided. The engine intake manifold includes a manifold chamber configured to receive positive crankcase ventilation (PCV) gas from a PCV conduit outlet, the manifold chamber including a condensate-containment tray with a plurality of baffles to form a plurality of separate cavities below the PCV conduit outlet.

First claim

1 . An engine intake manifold comprising:
a manifold chamber configured to receive positive crankcase ventilation (PCV) gas from a PCV conduit outlet, the manifold chamber including a condensate-containment tray with a plurality of baffles forming a plurality of separate cavities below the PCV conduit outlet.

2 . The engine intake manifold of claim 1 , where the manifold chamber includes a housing comprising at least one groove extending from at least one of the separate cavities into an intake manifold runner coupled to an engine cylinder.

3 . The engine intake manifold of claim 2 , where the grooves are curved extend in a vertical and lateral direction.

4 . The engine intake manifold of claim 3 , where the grooves extend over a peak of a ridge defining a boundary of one side of one of the separate cavities, the peak of the ridge positioned above the separate cavities.

5 . The engine intake manifold of claim 1 , where the baffles extend in a vertical direction.

6 . The engine intake manifold of claim 1 , where one or more of the baffles define a portion of a boundary of two adjacent cavities.

7 . The engine intake manifold of claim 1 , where the condensate-containment tray is positioned near or at a lower-most bottom of the manifold chamber.

8 . The engine intake manifold of claim 1 , where at least a portion of the condensate-containment tray is positioned in a valley between two cylinder banks and the engine intake manifold further comprises one or more intake manifold runners coupled to each of the cylinder banks.

9 . The engine intake manifold of claim 8 , where cylinders in the separate cylinder banks are arranged at non-straight angles to form a V-type cylinder configuration.

10 . The engine intake manifold of claim 1 , where the baffles are coupled to a housing defining the boundary of the manifold chamber.

11 . The engine intake manifold of claim 1 , where a portion of the condensate-containment tray is positioned vertically below a cylinder head attachment interface include in the engine intake manifold.

12 . An engine comprising:
a throttle; and an intake manifold positioned downstream of the throttle, the intake manifold including:
a manifold chamber coupled to a PCV conduit outlet and including a condensate-containment tray having a plurality of baffles forming a plurality of separate cavities below the PCV conduit outlet; and
a cylinder positioned downstream of the intake manifold.

13 . The engine of claim 12 , where the condensate-containment tray is positioned near or at a lower-most bottom of the manifold chamber.

14 . The engine of claim 12 , where the condensate-containment tray is positioned in a valley between two cylinder banks and the engine intake manifold further comprises one or more intake manifold runners coupled to each of the cylinder banks.

15 . The engine of claim 12 , where at least a portion of the baffles are laterally aligned.

16 . The engine of claim 14 , where the baffles extend in a vertical direction, and where the cavities are formed in two arrays separated by a ridge, each of the two arrays having a length longer than a width, the lengths aligned with one another and the cylinder banks.

17 . An engine intake manifold comprising:
a manifold chamber configured to receive positive crankcase ventilation (PCV) gas from a PCV conduit outlet, the manifold chamber including a condensate-containment tray having a plurality of baffles extending in a vertical direction and forming a plurality of separate cavities positioned below the PCV conduit outlet.

18 . The engine intake manifold of claim 17 , where the baffles intersect at perpendicular angles.

19 . The engine intake manifold of claim 17 , where the baffles intersect at non-perpendicular angles.

20 . The engine intake manifold of claim 17 , where the manifold chamber includes a housing comprising at least one groove extending from at least one of the separate cavities into an intake manifold runner coupled to an engine cylinder.
