arbcombo -- ECS Purifilter Plus Posted: 19 Jan 2011 11:00:03
Extension of ECS’ Purifilter PlusTM for On-road Applications. The Air Resources Board granted an extension for Engine Control Systems’ Purifilter PlusTM as a Level 3 Plus passively and actively regenerated diesel emission control system for use with certain on-road vehicles with model years between 1994 and 2010, certified by the United States Environmental Protection Agency. Approved engines are certified to particulate matter emission levels equal to or less than 0.1 grams per brake horsepower-hour, and may or may not be equipped with exhaust gas recirculation systems (EGR). The extension excludes EGR engines certified with diesel oxidation catalysts. Purifilter PlusTM uses a catalyzed silicon carbide wall-flow filter for passive regeneration and electric heating elements for active regeneration. It achieves at least an 85 percent reduction in emissions of diesel particulate matter. Specific conditions for which Purifilter PlusTM has been approved may be found in the conditional extension letter which will be posted within ten days on the ARB website at http://www.arb.ca.gov/diesel/verdev/verdev.htm .
