Abstract [en]

This report presents results from a project with the aim of investigating the potential environmental and health impact of emissions from ethanol, ethanol blended diesel fuels and to compare these with neat diesel fuels. The exhaust emissions were characterized regarding regulated exhaust components, particulate and semivolatile Polycyclic Aromatic Compounds (PAC) and with bioassays. The bioassays were mutagenicity and TCDD receptor affinity tests. Results: Neat ethanol fuels are 'low emission' fuels, while European diesel fuel quality (EDF) and an ethanol blended EDF are 'high emission' fuels. Other fuels, such as Swedish Environmental Class one (MK1) and an ethanol blended MK1, are 'intermediate' fuels regarding emissions. When using an oxidizing catalyst exhaust after- treatment device a reduction of harmful substances in the exhaust emissions with respect to determined exhaust parameters was found. The relatively low emission of PAH from ethanol fueled engines would indicate a lower cancer risk from ethanol than from diesel fuels due to this class of compounds. However, the data presented emphasize the importance of considering the PAH profile.
