Posted: 02 Jul 2014 10:38:21
Verification of the Donaldson DCM Diesel Oxidation Catalyst (DOC)
Muffler with Series 6000/6400 Catalyst Formulation for 
On-Road Applications. 

The Air Resources Board (CARB) has modified the verification of
the Donaldson DCM Diesel Oxidation Catalyst (DOC) Muffler with
Series 6000/6400 catalyst formulation for select 1988 through
1990 model year diesel engines used in on-road applications
operating on standard CARB or lower sulfur content diesel fuel. 
The system employs a diesel oxidation catalyst to achieve at
least a 25 percent reduction in particulate matter emissions,
qualifying it for Level 1 plus verification.  Specific engine
families and conditions for which the DCM DOC Muffler with Series
6000/6400 catalyst formulation has been approved along with the
Executive Order may be found on the ARB website at:
