A diesel oxidation catalyst (DOC) is an aftertreatment component that is designed to convert carbon monoxide (CO) and hydrocarbons into carbon dioxide (CO2) and water. The device is used on all our EU Stage IV/U.S. EPA Tier 4 Final products – from the 400F through to the 1206F.
It doesn’t matter if you are running your diesel engine on the road or off, you must still adhere to strict emissions standards. A diesel oxidation catalyst (DOC) is an aftertreatment device that can help you do that, as it effectively turns CO and hydrocarbons into CO2 and water vapour.
The DOC is part of the technology we offer to assist you in meeting Stage IV and Tier 4 Interim/Final emissions standards. It breaks down pollutants in the exhaust stream from a diesel engine, helping to reduce particulate matter (PM). It’s similar to a catalytic converter in a car.
Both carbon monoxide and hydrocarbons are converted in the DOC to carbon dioxide and water vapour. Exhaust gases are optimised so that they can perform in other systems in the aftertreatment, such as the selective catalytic reduction (SCR) or diesel particulate filter (DPF).
How the diesel oxidation catalyst (DOC) works
Our DOCs provide a simple solution for original equipment manufacturers (OEMs). They’re easy to install and maintain and don’t require any additional control from the machine operator.
In many cases, the need for a muffler can be eliminated, and our DOCs can also allow for a wider ratings envelope. Concentrations of NO and NO2 can be optimised in the exhaust stream, and if your engine has SCR, this will make it more efficient and reduce diesel exhaust fluid (DEF) consumption requirements.
Using a DOC also enables additional passive regeneration in DPF systems.

Emission standards require engine manufacturers to reduce certain engine emissions, including nitrogen oxides (NOx). One of the options available for reducing NOx emissions is selective catalytic reduction (SCR), which is used on a number of our engines.Learn More
One of the technologies available for the reduction of oxides of nitrogen (NOx) is exhaust gas recirculation (EGR).Learn More
Reducing particulates and optimising fuel consumption are primary reasons for adding high pressure common rail (HPCR) systems to an engine. The HPCR is used in diesel engines across our range, providing improved fuel efficiency through a more efficient combustion process.Learn More
