What does a diesel oxidation catalyst reduce?
The diesel oxidation catalyst is very effective in controlling carbon monoxide and hydrocarbon emissions from diesel engines, including the PAH and hydrocarbon derivatives such as aldehydes.
What is the purpose of a diesel oxidation catalyst?
3.1 Diesel Oxidation Catalysts A diesel oxidation catalyst (DOC) is employed to remove CO and hydrocarbons using the oxygen in the exhaust (5–15% of the gases). It also oxidizes NO to NO2, which, if left unchecked, results in elevated levels of NO2 at the exhaust pipe exit.
At what temperature does oxidation begin within a diesel oxidation catalyst?
A minimum exhaust temperature of about 200°C is necessary for the catalyst to “light off”. At elevated temperatures, conversions depend on the catalyst size and design and can be higher than 90%.
Can a diesel oxidation catalyst be cleaned?
In general, cleaning requires removing the DOC from the vehicle, heating it, and using compressed air combined with a vacuum system to blow out the ash and capture it in a sealed container. Professional cleaning services are available.
What is in diesel oxidation catalyst?
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. Both carbon monoxide and hydrocarbons are converted in the DOC to carbon dioxide and water vapour.
How much is a diesel catalytic converter worth?
|DPF Catalytic Converter A grade of a catalytic converter that are generally used to remove dirt, dust, or other contaminants from diesel engines. GET QUOTE VIEW METAL DETAILS||$9.00/each|
|Flow Cats Flow Cats. GET QUOTE VIEW METAL DETAILS||$37.00/each|
What emissions are oxidized by the diesel oxidation catalyst?
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.
How often should a DPF filter be cleaned?
about every 200,000 miles
When Is It Time To Have Your DPF or DOC Cleaned? A good rule of thumb is to go in for a cleaning about every 200,000 miles or less, depending on your duty style. It is possible to burn off this excess ash and soot on your own using either passive or active regeneration.
How does oxidation catalyst work?
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. It breaks down pollutants in the exhaust stream from a diesel engine, helping to reduce particulate matter (PM).

What catalytic converters are worth the most in scrap?
What’s Inside A Catalytic Converter?
- Platinum – Platinum being used tends to be the best metal for overall performance in the catalytic converter field.
- Palladium – Generally more expensive to use then Platinum, so it tends to be a higher-end luxury item for catalytic converters.
What happens if you don’t clean DPF?
If the soot trapped by a DPF is not removed regularly, the filter can’t work properly. This results in a vast build-up of soot. When the DPF is cleaned, the excess soot is burned off. This lowers dangerous emissions and will reduce the amount of black smoke emitted by your vehicle.
How is an oxidation catalyst used in a diesel engine?
A diesel oxidation catalyst (DOC) is employed to remove CO and hydrocarbons using the oxygen in the exhaust (5–15% of the gases). It also oxidizes NO to NO2, which, if left unchecked, results in elevated levels of NO 2 at the exhaust pipe exit.
What is the aftertreatment system of a diesel engine?
The aftertreatment system consists of a close-coupled diesel oxidation catalyst (DOC), a diesel exothermic catalyst (DEC) and a catalytic Diesel Particulate Filter (cDPF). Both DEC and cDPF are packed into a single canister with a small gap between them.
Can a 3 way catalyst be used in a diesel engine?
Therefore, the three-way catalyst used in the gasoline engine usually cannot be used in the diesel engine although some research was conducted on using a three-way catalyst on diesel engines to explore the potential of emissions control (e.g., Sung et al., 2009; Simescu et al., 2010 ).
How is the efficiency of a catalytic converter determined?
The efficiency of the catalytic converters is related to air–fuel ratio, light-off temperature and light-off time, space velocity, flow restriction characteristics and the durability features. The light-off temperature is defined as the temperature at which 50% conversion efficiency is achieved.
