  1. Emission control technology for marine applications

  2. Diesel enginespresent in marine applications DEC SCOPE Trend in repowering

  3. After treatmentsolutionsfordieselengines • DPF Diesel particulate filter/ Captures and oxidizes PM • Frequently used on passenger car E5/E6 • Frequently used on trucks EPA ‘07 • Implemented for many trucks EUR VI • Good potential for rail applications • Good potential for inland vessel / local legislation • SCR Selective catalytic reduction/ Reduces NOX by means of a reagent • Frequently used on trucks EUR IV,V,VI • Best potential for inland vessel emission reduction • Best potential for MARPOL TIER III Possible with fuel below 250 - 350 PPM sulphur Possible with high sulphur fuel Fuel optimised engine => LOW CO2

  4. Aftertreatment technology for inland vessels

  5. Facts Inland vessels have access to good quality fuel Inland vessels use mainly medium and high speed diesel engines A high proportion of inland vessels have engine load profiles allowing the use of high efficient aftertreatment technology

  6. DPF solutionsformarine dieselengines Best combination for inland vessels

  7. SCR solutions

  8. SCR solutionsinlandvessels

  9. Combined aftertreatment systems for inland vessel applications

  10. Option 1 : DPF => SCR Diesel injecton AdBlueinjecton Diesel injecton Mixer DOC Hydro Cat.
