arbcombo -- Extension of ECS Combifilter Verification Posted: 04 May 2007 14:30:17
ARB extended the verification of Engine Control Systemsí Combifilter diesel particulate filter to include model years 2005 to 2007 diesel engines used in off-road applications operating on ultra low sulfur diesel fuel or bio-diesel (B20). The Combifilter system employs an actively regenerated uncatalyzed diesel particulate filter to achieve an 85 percent reduction in particulate matter emissions, qualifying it for Level 3 Plus verification. Specific engine families and conditions for which the Combifilter has been approved may be found in the Executive Order posted on our website at: http://www.arb.ca.gov/diesel/verdev/level3/level3.htm.
