Abstract:

the experimental work was carried out according to a test protocol, applying conventional procedures for sampling and analysis of regulated and unregulated polluting species. Two Euro 4 passenger cars were fuelled with a reference gasoline and with two blends containing 5% (E5) and 10% (E10) by volume of bioethanol, prepared in laboratory starting from the same base stock. No statistically significant emission variation of the regulated species and of the main aldehydes was observed in the exhaust. A reduction trend of the particulate matter soot fraction for both cars powered with E5 and E10, but no appreciable change in the particle number measured by ELPI instrument was observed. Moreover a statistically significant but weak decrease of carbon dioxide emission and of fuel con¬sumption, with increasing concentration of ethanol in the gasoline, was detected for both cars.
