Fuel Effects on Regulated and Unregulated Emissions from Two Commercial Euro V and Euro VI Road Transport Vehicles

Substantial advances in European road vehicle emissions have been achieved over the past three decades driven by strengthening revisions legislation and enabled fuel, engine control technologies. As both technology Europe continue to evolve, Concawe has conducted a study examine effects that fuels can on emissions, this case from commercial vehicles. A bus certified Euro VI level delivery truck V tested chassis-dyno World Harmonized Vehicle Cycle (WHVC) Transport for London Urban Inter-Peak (TfL UIP) test cycles with six fuels: an EN590-compliant B5 (petroleum diesel containing 5% biodiesel volume), bioderived paraffinic diesel, 50:50 blend of aforementioned fuels, low-density petroleum-derived B5, B30 same additized high dose cetane number improver (CNI). Results show reduced NOx reductant (AdBlue) consumption due lower engine-out emissions. More surprisingly, higher hydrocarbon were observed some truck. Compared without CNI did not affect tank-to-wheel (TTW) CO2, volumetric fuel or statistically significant margins. When considered findings complementary light-duty study, it is apparent could offer overall benefits affecting local air quality greenhouse gas TTW basis. The addition fatty acid methyl ester (FAME) levels be used increase renewable contribution resulting no penalty modern Compatibility these existing fleet would require further specific consideration. Outside properties considerations, aftertreatment systems N2O at tailpipe through chemical reactions catalyst. This translate into about 10% GHG vehicle.
