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).
What are the strengths of our solution?
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.
- Converts carbon monoxide (CO) into carbon dioxide (CO2) and water
- Can eliminate muffler requirement
- Harmful particulates are oxidised into harmless products
We’ve been on an exciting journey of innovation and dynamic product development as emission standards have become more stringent over the years.
Our solutions provide OEMs with improved performance and fuel efficiency, dependable power and a lifetime of low costs for the operator.
Engine optimisation and integration
Collaboration with our customers is the cornerstone of Perkins engine design – and it’s the reason we’re a leader in diesel engine development.
Fuel quality - alternative fuels
Fuel quality around the world can vary markedly and this can affect both the short-term performance of your engine, and potentially its long-term future.
