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 .
