Abstract: A transmission pan with integrated heat exchanger for an automobile vehicle includes a transmission pan. A heat exchanger is positioned entirely within transmission pan and is fixed to a bottom inner surface of the transmission pan. The heat exchanger includes a substantially flat surface. The surface includes a first flow port defining a transmission fluid inlet port, and a second flow port defining a transmission fluid outlet port. A cooling header assembly has an inlet header and an outlet header, each fixed to and sealed at an entrance through a wall of the heat exchanger. The inlet header and the outlet header also each penetrate an outer wall of the transmission pan and are each fixed to and sealed where the penetrations of the inlet header and the outlet header contact the outer wall.

Abstract: Exemplary embodiments of the present invention provide devices, systems and methods for distribution of an engine exhaust gas to one or more exhaust treatment devices. In one embodiment, an exhaust flow diffuser is provided including a conduit defining an inlet opening, an outlet opening and a flow path therebetween. The conduit includes a first section disposed proximate to the inlet opening and a second section disposed proximate to the outlet opening. The second section has an increasing diameter along its length. The conduit is formed by a first member and a second member both of which extend between the inlet opening and outlet opening to form a portion of the first section and the second section. The first member and the second member each include an engagement feature that extends between the inlet opening and outlet opening.
