Diesel Oxidation Catalysts (DOC)

BASF ECMS's Diesel Oxidation Catalyst (DOC) technology controls emissions of hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) from diesel vehicles.

BASF ECMS's Diesel Oxidation Catalyst (DOC) technology controls emissions of hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) from diesel vehicles. It was the first catalytic emissions control system to meet U.S. Environmental Protection Agency (EPA) certification requirements for the U.S. Urban Bus Retrofit Program and offers many benefits. 

  • Can reduce HC and CO emissions by 50% or more  

  • Integrated, easy-to-install bolt-on technology

  • Fuel sulfur tolerance

  • Easy maintenance; needs no additional parts or sensors  

  • U.S. EPA approved for two- and four-stroke diesel engines      

Applications

1
ECMS Application
BASF ECMS DOCs have millions of miles of proven performance in light duty passenger cars, urban buses, medium duty trucks and heavy-duty truck applications.
2
ECMS Application
ECMS DOC technology platforms and precise patented manufacturing process enable ECMS to provide DOC technologies that light off at very low temperatures using a minimal amount of precious metal.
3
ECMS Application
The catalysts are also currently in use on tens of thousands of retrofitted vehicles around the world.
