arbcombo -- Extension of the Donaldson SEF Muffler System Posted: 12 Feb 2013 08:36:00
Verification of the Donaldson SEF Muffler System for On-Road Applications. The Air Resources Board (ARB) modified the verification of the Donaldson Semi-Active Electric Filter (SEF) Muffler System. The modifications include parts changes and changes to the scope of the verification. The SEF Muffler System employs a diesel oxidation catalyst, heating element, and an un-catalyzed diesel particulate filter with an Emissions Device Monitor Kit 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 SEF Muffler System has been approved along with the Executive Order will be available shortly on ARBís website at: http://www.arb.ca.gov/diesel/verdev/companies/donaldson/sef.htm You are receiving this single arbcombo email because you are a subscriber to or have made a public comment to one or more of the following lists: diesel-retrofit, ms-mailings.
