Diesel Particulate Filters (DPF)

The reduction of diesel particulates is considered a top priority. A DPF is the best solution to address this problem. The soot particles exiting a diesel engine are trapped in a special filter made out of porous ceramic-like material. A special coating facilitates a burn-off of the trapped soot particles and therefore allows for continuous operation without the built-up of soot and an increase of backpressure in the exhaust system.


Diesel Oxidation Catalysts (DOC)

Excess hydrocarbon emissions can be reduced with a DOC. A DOC operates similar to a three-way catalytic converter as used on every vehicle on the road today. These technologies are very cost effective in reducing the harmful pollutants in diesel emissions.


Selective Catalytic Reduction (SCR)
