With Bharat Stage VI (BSVI) regulations on the horizon [3],[4]tighter particulate matter (PM) regulations will require the use of wall flow diesel particulate filters for on-road heavy duty (HD) diesel engines in India. The Indian HD vehicle market is very cost sensitive, especially with the majority of engine displacement being less than 7L [5] therefore, after treatment cost plays a significant role in design of the system. Robust wall flow diesel particulate filter solutions with the ability to deliver high filtration requirements required for particle number regulations can be designed in a cost-efficient manner. In this paper advanced design for diesel particulate filters with pressure drop, ash capacity, regeneration, and filtration performance are discussed. Corning’s asymmetric cell technology (ACT) was created to improve ash capacity and reduce pressure drop and has the potential to downsize up to 45%.
