Abstract

An intake manifold assembly includes an intake manifold body defining an interior manifold cavity. The intake manifold further includes a throttle mount coupled to the intake manifold body and defining a mount passage in fluid communication with the interior manifold cavity. The throttle mount is configured to be coupled to a throttle assembly. The intake manifold assembly further includes a supplemental gas conduit including a first supplemental gas conduit portion coupled to the intake manifold body. The supplemental gas conduit further includes a second supplemental gas conduit portion in fluid communication with the first supplemental gas conduit portion. The second supplemental gas conduit portion is coupled to the throttle mount and is configured to deliver supplemental gases into the mount passage to mix the supplemental gases with intake air flowing through the mount passage.
