Abstract: An exhaust silencer includes a housing defining an interior and a tube disposed in the interior and defining an opening. A gas-flow deflector is configured to heat shield an interior wall of the housing from exhaust gases exiting the opening. The deflector has a deflector plate and a riser. The riser has a first portion connected to the interior wall and a second portion connected to a backside of the deflector plate to suspend the deflector plate in the interior such that the backside is completely spaced from the interior wall to form an insulating airgap therebetween.

A gas-flow deflector is configured to heat shield an interior wall of the housing from exhaust gases exiting the opening. The deflector has a deflector plate and a riser. The riser has a first portion connected to the interior wall and a second portion connected to a backside of the deflector plate to suspend the deflector plate in the interior such that the backside is completely spaced from the interior wall to form an insulating airgap therebetween.

Abstract: An air flow optimization device is provided for motor vehicle heat exchangers. The device includes a body having a first air flow opening with an inlet side and an outlet side. A series of fixed vanes are provided across the opening and divide the opening into a plurality of air flow channels.

Abstract: An underbody air and thermal management system is provided for a motor vehicle. That system includes an aero shield having a louver system selectively displaceable between an open position and a closed position. The system also includes an air dam that is selectively displaceable between a home position and a deployed position. Still further, the system includes a control system to displace the louver system between the open position and the closed position and the air dam between the home position and the deployed position so as to provide the best possible balance between aerodynamic airflow, under vehicle ground clearance and under hood or engine bay cooling.
