In an earlier study, it was\nconcluded that cyclic oxygenates consistently outperformed\ntheir straight and branched counterparts at equal oxygen\ncontent and with respect to lowering soot emissions. A clear\ncorrelation was reported linking soot and CN, with lower CN\nfuels leading to more favorable soot levels. It was concluded\nthat a lower CN fuel, when realized by adding low reactive\ncyclic oxygenates to commercial diesel fuel, manifests in\nlonger ignition delays and thus more premixing. Ultimately, a\nhigher degree of premixing, in turn, was thought to suppress\nsoot formation rates. Such compounds have the advantage to\nbe stable in blends with fossil diesel fuel, to have a boiling\npoint close to the diesel fuel range, and have the potential to\nbe produced in a renewable way from lignin, which has a\nsimilar hexagonal hydrocarbon basis, albeit in polymer form.\nLignin is currently a widely available second generation\nbiomass waste stream, found in for example the paper pulp\nindustry and cellulosic ethanol plants. In the present work,\nblends of diesel and cyclohexanone were tested in a LD\nsingle cylinder research diesel engine in order to evaluate its\neffects on the combustion process and pollutant emissions,\nemploying both conventional (i.e. mixing-controlled)\ncombustion (at medium/high engine loads) and premixed\ncombustion (at medium/low loads). The results suggest that\nthe combination of low CN and fuel oxygen appears to have a\nfavorable impact on both fuel efficiency and overall\nemissions in premixed-mode. For mixing-controlled\ncombustion, at medium/high engine loads, the negative\neffects of low CN (e.g. retarded combustion phasing) can be\novercome with an appropriate calibration of the injection\nparameters. The high unburnt hydrocarbon emissions at low\nload, conversely, require a further development of the\ncombustion system design, as well as the after-treatment\ndevice. Finally, to realize a more and more precise control of\nthe in-cylinder air-fuel charge, before and during the\ncombustion, the future PCCI fuels have to be tailored to the\nspecific combustion process characteristics. In this\nframework, renewable low CN oxygenated fuels might\nfunction as an enabler for PCCI combustion engines." ; prodottidellaricerca:prodottoDi modulo:ID2180 , istituto:CDS058 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA14610 , unitaDiPersonaleInterno:MATRICOLA6769 . ns11:ID317753 pubblicazioni:rivistaDi prodotto:ID189833 .
