For Higher Wash Coat Loads, Enabling Integrated NOx Solutions
in Light-Duty Diesel Systems

Vehicle and engine manufacturers worldwide are striving to improve the fuel efficiency and performance of diesel engines while meeting NOx, soot particle mass, and soot particle number emissions limits under real-world driving conditions. Integrating SCR catalysts on diesel particulate filters is a leading approach to meet emerging challenges with a compact, fuel-efficient, high-performance solution.

Product Highlights

Product Highlights

Corning® DuraTrap® AT HP filters are designed with a higher porosity and optimized microstructure. This enables low backpressure at high washcoat loads and excellent filtration efficiency under all driving conditions.

Corning’s aluminum titanate material provides low thermal expansion to enable durable monolithic construction. Our monolithic design allows:

  • Low pressure drop and excellent regeneration efficiency to help improve fuel consumption
  • Increased ash storage capacity and about 12% larger filtration surface area compared to segmented filters
  • More effective utilization of washcoat

Filter shape can be optimized for systems with space constraints and diverse configurations.Corning’s innovative asymmetric cell technology (ACT) option can help manage lifetime pressure drop requirements and provides ash storage benefits through larger inlet channels.
