Diesel Oxidation Catalysts (DOC)

Nox Trap Doc And Scro F 3

BASF'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
  • Easy maintenance; needs no additional parts or sensors
  • Fuel sulfur tolerance
  • U.S. EPA approved for two- and four-stroke diesel engines

BASF DOCs have millions of miles of proven performance in light duty passenger car, urban bus, medium duty truck and heavy duty truck applications.

BASF DOC technology platforms and precise patented manufacturing process enable BASF to provide DOC technologies that light off at very low temperatures using a minimum amount of precious metal.

The catalysts are also currently in use on tens of thousands of retrofitted vehicles around the world.

For example, in Hong Kong thousands of delivery vans, sanitation trucks, pieces of construction equipment and other diesel vehicles have been retrofitted with BASF DOC technology under a program administered by the Hong Kong Special Administrative Region.
