EMISSIONS FROM A EURO V TRUCK FUELED BY DIESEL, BIODIESEL BLENDS, NEAT BIODIESEL AND VEGETABLE OIL

Abstract

The substitution of conventional fuels (gasoline, diesel) by renewable biofuels including biodiesel and vegetable oil is considered as a potential solution not only for satisfying the fuel demand but also for reducing emissions. In this study, a Euro V truck fueled with a low sulphur diesel fuel, a neat biodiesel (B100), biodiesel blends (B7 and B10), a mixture of 7% biodiesel, 3% vegetable oil and 90% diesel (B7+3) and a straight vegetable oil was tested on chassis dynamometer under the European stationary cycle. During the test, emissions in the exhaust gas were collected and measured following the standard methods. Besides the regulated emissions, particle number and size distribution, which were sampled by volatile particle remover system compliant with the PMP requirement, as well as soot concentration, were also considered. Results show the effects of the tested fuels on the engine characteristics as well as the emissions.
