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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
