Abstract
Dow Automotive has developed an ACM DPF substrate, characterized with light-weight, low pressure-drop, rapid regeneration, and excellent chemical resistance at high temperature. An uncatalyzed DPF was tested on a 2.0L common-rail diesel engine for over 100 soot loading and regeneration cycles, which included a combination of controlled regenerations, uncontrolled regenerations and incomplete regenerations. The DPF demonstrated high filtration efficiency and physical integrity throughout the entire test.
The ACM DPF has also demonstrated excellent catalyst coating capability and performance. An ACM DPF with a total volume of three-liter and coated with the same catalyst formulation as the original catalyzed DPF, was used to replace the OEM four-liter catalyzed SiC DPF on a 2005 model-year 1.9L European diesel passenger car. It was demonstrated that the ACM DPF has lower pressure drop and faster regeneration than that of the OEM DPF. Durability test of 20,000km with city duty cycles has been completed and it showed that the ACM DPF maintained high filtration efficiency and physical integrity.
