heal.abstract In this study, regulated, unregulated exhaust emissions and fuel consumption with ultra low sulphur diesel and soy-based biodiesel blends at proportions of 10 and 30% v/v have been investigated. A Euro 4 compliant SUV, equipped with a 2.2 litre common-rail diesel engine and an oxidation catalyst was tested on a chassis dynamometer with constant volume sampling (CVS) technique. Emission and fuel consumption measurements were performed over the New European Driving Cycle (NEDC) and the non-legislated Artemis driving cycles which simulate urban, rural, and highway driving conditions in Europe. The regulated pollutants were characterized by determined NOx, PM, CO, and HC. CO2 was also quantified in the exhaust. Overall, 16 PAHs, 4 nitro-PAHs, 6 oxy-PAHs, 13 carbonyl compounds and particulate alkanes ranged from C13 to C35 were determined in the exhaust. The experimental results showed that the addition of biodiesel decreased the emissions of PM, CO and HC and increased NOx emissions during real-world driving. CO2 emissions and fuel consumption followed similar patterns and increased. Carbonyl compounds were increased for all fuel/cycle combinations. PAH emissions were found to decrease with biodiesel, with some exemptions in certain compounds. An increase was observed on the straight- chain alkanes composition with biodiesel over all driving cycles. © 2009 SAE International. en
