arbcombo -- Verification of ECS Purifilter for Off-road Posted: 21 Oct 2008 14:16:41
Conditional Verification of the ECS PurifilterTM for Off-road Equipment. The Air Resources Board conditionally verified Engine Control Systemsí PurifilterTM as a Level 3 Plus passively regenerated diesel emission control system for use with off-road equipment powered by certain off-road diesel engines with model years between 1996 and 2008. Approved engines are certified to a particulate matter emission level equal to or less than 0.2 grams per brake horsepower-hour, are rated to at least 50 horsepower and at most 750 horsepower, and are not equipped with exhaust gas recirculation systems. PurifilterTM uses a catalyzed silicon carbide wall-flow filter for regeneration to achieve an 85 percent reduction in emissions of diesel particulate matter. Specific conditions for which PurifilterTM has been approved may be found in the conditional verification letter which will be posted within ten days on the ARB website at http://www.arb.ca.gov/diesel/verdev/verdev.htm .
