Performance and pollutant emissions from transient operation of a common rail diesel engine fueled with different biodiesel fuels

Three fatty acid methyl ester fuels (from rapeseed, sunflower and soybean vegetable oils) and their blends (30% v/v) with diesel fuel were tested under New European Driving Cycle (NEDC) on an engine test bench. This allowed comparing engine pollutant emissions trends under transient operation. FAME fuels and their blends produced higher specifics emissions of nitrogen oxides (NOx), total hydrocarbons (THC) and carbon monoxide (CO) and lower...
