Diesel/Soy Methyl Ester Blends Emissions Profile from a Passenger Vehicle Operated on the European and the Athens Driving Cycles 2007-01-4043

The need of a more realistic and dynamic driving cycle which simulates real-world driving conditions in the largest city in the greater area of Balkans, led to the development of the Athens Driving Cycle (ADC). Emission and fuel consumption measurements were conducted over the ADC and compared with those of the New European Driving Cycle (NEDC) using a chassis dynamometer. A Euro II compliant diesel vehicle was used in this study, fuelled with a typical automotive diesel fuel and biodiesel blends at proportions of 5, 10, and 20 % respectively. The unregulated emissions were characterized by determining the soluble organic fraction (SOF) in the particulate matter, together with qualitative hydrocarbon analysis present in the SOF fraction, and of carbonyl compounds (aldehydes, ketones). Emissions of NOx, CO, THC, CO2, and PM10 were also measured over the two test cycles.
