arbcombo -- Modifications to the Donaldson Level 1 Verification

Posted: 16 Mar 2011 13:49:46
Modifications to the verification of the Donaldson DCM Diesel
Oxidation Catalyst (DOC) Muffler systems for On-Road
Applications. 

The Air Resources Board (ARB) has modified the Level 1
verifications of the Donaldson DCM Diesel Oxidation Catalyst
(DOC) Muffler systems.  These systems achieve at least a 25
percent reduction in particulate matter emissions, and are used
in on-road applications for various model year engines.  Specific
engine families and conditions for which the DCM DOC Muffler
systems have been approved may be found in the Executive Order
and attachment which will be posted within ten days on the ARB
website at: http://www.arb.ca.gov/diesel/verdev/verdev.htm.
