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.

Optimizacija propelera

Unapređenje elise

Učinkovitost brodskog propelera raste s njegovim promjerom. Međutim propeleri brodova unutarnje plovidbe, zbog ograničene raspoložive dubine vode, vrlo su malog promjera. Kao posljedica, učinkovitost je vrlo niska s obzirom da ti propeleri moraju proizvesti relativno veliki potisak. Danas, gole propelere rijetko tko primjenjuje na plovilima unutarnje plovidbe s obzirom da je apsorpcija energije ograničena na oko 300 kW / m2 površine propelera.

Optimizacija protoka propelera

Poboljšanja trupa

Razlika u brzini propelera Slipstream (velike brzine) i krmenog protoka broda (niska brzina) uzrokuje dodatne turbulencije iza broda. Energija potrebna za proizvodnju turbulencija je na trošak efikasan pogon broda.
