Selektivna katalitička redukcija (SCR)

The technology of Selective Catalytic Reduction (SCR) is applied by the injection of a urea solution (CO(NH2)2) or ammonia (NH3) in the exhaust gas at a temperature of 290 – 350 °C. A catalyst is placed in the exhaust gas channel, where the reducing agents react with the nitrogen oxides forming nitrogen and water.

Fuel-water emulsion (FWE)

The application of fuel-water emulsion technology reduces both particulate matter and NOx-emission. It can be regarded as a most promising technology for greening the inland waterway transport. After emulsifying water and fuel before injection, a ‘micro explosion’ reduces the fuel oil droplets into numerous smaller ones. These smaller droplets ignite and burn easier than the bigger droplets. Pm and soot creation zones are reduced, the thermal effectiveness improves and fuel consumption decreases. FWE also leads to a cooling down effect of the combustion chamber temperature. This results in a reduction of NOx emission.

Diesel particulate filters (DPF)

Diesel particulate filters (DPF) are devices that physically capture diesel particulates to prevent their release to the atmosphere. Diesel particulate filter materials have been developed that show impressive filtration efficiencies, in excess of 90%, as well as good mechanical and thermal durability.
