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.

Abstract: A high-pressure connection for corrosive fluids includes a female member having a female surface and a male member having a male surface, both of which may be formed from stainless steel. The male surface is configured to have a complementary shape to the female surface. A malleable coating substantially covers the male surface and may be formed from copper. The male surface is configured to be pressed into the female surface, to sandwich the malleable coating and effect a fluid seal therebetween. The female surface may be substantially frusto-conical and the male surface substantially spherical. A supply line may be brazed onto the male member and the malleable coating configured to act as a brazing compound therefore. The fluid seal may be characterized by the absence of a gasket or an o-ring and the malleable coating between 15 to 30 microns.
