Diesel Oxidation Catalyst (DOC)

Our Experience is Your Solution.
Cummins Emission Solutions makes it simple with a Diesel Oxidation Catalyst (DOC) designed to retrofit existing vehicles. Easy to install and maintenance free, the DOC is reducing emissions from on-road vehicles and off-road equipment around the globe.

• Can be used with low-sulfur (500 ppm) or
  ultra-lowsulfur diesel fuels (15 ppm)
