Muffler with Series 6000/6400 catalyst formulation and Spiracle™
Closed Crankcase Ventilation (CCV) Filtration System 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 and Spiracle™ Closed
Crankcase Ventilation (CCV) Filtration System 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 DOC with a CCV filtration
system to achieve at least a 25 percent reduction in particulate
matter emissions, qualifying it for Level 1 plus verification. 
Specific details and conditions for which the DCM DOC Muffler
with Series 6000/6400 catalyst formulation and Spiracle™ Closed
Crankcase Ventilation (CCV) Filtration System has been approved
may be found on ARB website at:
