As automakers set new targets for fuel efficiency and noise reduction, their suppliers are faced with the task of providing products to complement sophisticated electronic and plastic engine components.  Dana is meeting this challenge with the development of Thermal Acoustical Protective Shields (TAPS).

TAPS are designed to shield engine components from the extreme heat generated during engine operation, and are also used to reduce engine noise, vibration, and harshness (NVH).

To design TAPS, engineers from Dana’s Victor Reinz Division use both thermal and acoustical analysis techniques.  For example, 3-D computer-aided design modeling is used to develop new shield models that can be evaluated with computer manufacturing simulation before designs are finalized.  These research and development processes offer Dana customers fully integrated capabilities to aid speed-to-market.

Dana’s TAPS incorporate three stamped layers, including an insulating filler.  This three-layer, fully hemmed assembly provides superior heat resistance and noise and vibration reduction at a competitive price.  Moreover, the division’s three-layer shields typically weigh less than other manufacturers’ two-layer models.

Demand for TAPS technology is growing rapidly in North America.  While the original focus was exhaust manifold shields on passenger cars and light trucks, today TAPS are used as turbocharger mounting shields, fuel tank shields, and motor mount shields.  Dana has also begun to explore the potential for TAPS in heavy-duty diesel applications.
