arbcombo -- ECS Purifilter Extension Posted: 18 Jan 2008 11:37:54
The Air Resources Board has extended the on-road verification of the Engine Control Systems (ECS) Purifilter H diesel particulate filter to include several parts changes and certain 1993, 2005, and 2006 model year on-road diesel engines. In addition, the ECS Purifilter H may also be applied to on-road engines using diesel fuel that contains as much as 20 percent biodiesel. The Purifilter H is a passively-regenerating filter that uses a silicon carbide wall-flow filter to achieve an 85 percent reduction in particulate matter emissions. Specific conditions for which the Purifilter H has been approved may be found in the Executive Order which may be found on the ARB website at http://www.arb.ca.gov/diesel/verdev/verdev.htm .
