Filter Product Limits
Soot Mass Limit – Operating Window Concept • Instead of looking at the soot load it is advantageous considering the limit for the maximum temperature and temperature gradient in the filter
• The clean (unloaded) filters show only small differences even at high mass flow rates • Lower soot loaded backpressure observed with increasing filter length at the same specific soot load

ACT Design (Asymmetric Cell Technology)
Experimental Engine Bench Data • Lower pressure drop with ash for ACT design over entire flow range • Backpressure benefit even more pronounced with soot • Larger inlet channel diameter and therefore larger inlet channel volume providing higher ash storage capacity

*Values provided are directional only. Results may vary depending on catalyst influence and system specific details. Results are based on Corning‘s severe drop to idle testing. Gradients are defined using a specific TC layout with 10mm spacing.
• Note: clean pressure drop taken after successful regenerations
