Diesel enginespresent in marine applications DEC SCOPE Trend in repowering
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
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
DPF solutionsformarine dieselengines Best combination for inland vessels
