Particle number and size emissions from a small displacement automotive diesel engine / Federico Millo in Industrial & engineering chemistry research, Vol. 51 N° 22 (Juin 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 22 (Juin 2012) . - pp. 7565-7572 Titre : Particle number and size emissions from a small displacement automotive diesel engine : Bioderived vs conventional fossil fuels Type de document : texte imprimé Auteurs : Federico Millo, Auteur ; Davide Simone Vezza, Auteur ; Theodoros Vlachos, Auteur Année de publication : 2012 Article en page(s) : pp. 7565-7572 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Fossil  fuel  Diesel  engine  Particle  number Résumé : Experimental work has been carried out on a small displacement Euro 5 automotive diesel engine fueled alternatively with ultralow sulfur diesel (ULSD) and with two blends (30% vol) of ULSD, with two different fatty acid methyl esters (FAME) obtained from rapeseed methyl ester (RME) and jatropha methyl ester (JME). The engine-out particulate matter (PM) emissions have been characterized in terms of number and mass size distributions; measurements were performed under different engine operating conditions that are representative of the New European Driving Cycle (NEDC), including cold start of the engine. No significant differences were detected in the particle numbers (PN) for the different fuels under steady-state operating conditions, while a moderate reduction in particle mass size distribution was observed for the biofuel blends. The effects on PN emissions due to shifts in the engine operating points on the calibration maps, caused by the different fuel characteristics, have been shown to be significantly larger than the effects due to the different combustion characteristics of the biofuel blends, thus highlighting the need for a specific adjustment of the engine calihration.
