The exploration strategy was focused on the management of the timing and injection pressure to achieve a condition in which the whole amount of fuel was delivered before ignition. The aim of the paper was to evaluate the potential to employ fuel blends having low cetane number and high resistance to autoignition to reduce engine out emissions of NOx and smoke without significant penalty on engine performance. \nFuel blends were mixed by the baseline diesel (BU00) with 20% and 40% of n-butanol by volume. The n-butanol was taken by commercial production that is largely produced through petrochemical pathways although the molecule is substantially unchanged for butanol produced through biological mechanisms.\nThe experimental activity was performed on a turbocharged, water cooled, DI diesel engine, equipped with a common rail injection system. The engine equipment includes an exhaust gas recirculation system controlled by an external driver, a piezo-quartz pressure transducer to detect the in-cylinder pressure signal and a current probe to acquire the energizing current to the injectors. Engine tests were carried out at 2500 rpm and 0.8 MPa of BMEP exploring the effect of start of injection, O2 concentration at intake and injection pressure on combustion behavior and engine out emissions. The in-cylinder pressure and rate of heat release were investigated for the neat diesel and the two blends to evaluate engine performance and exhaust emissions both for the conventional diesel and the advanced premixed combustion processes.\nThe management of injection pressure, O2 concentration at intake and injection timing allowed to realize a partial premixed combustion by extending the ignition delay, particularly for blends. The main results of the investigation made reach smoke and NOx emissions due to the longer ignition delay and a better mixing control before combustion. The joint effect of higher resistance to auto ignition and higher volatility of n-butanol blends improved emissions compared to the neat diesel fuel with a low penalty on fuel consumption."@en ; prodottidellaricerca:prodottoDi modulo:ID2181 , istituto:CDS058 ; pubblicazioni:autoreCNR unitaDiPersonaleEsterno:ID10782 , unitaDiPersonaleInterno:MATRICOLA22106 , unitaDiPersonaleInterno:MATRICOLA5059 . @prefix parolechiave: . prodotto:ID37128 parolechiave:insiemeDiParoleChiave . ns12:ID386967 pubblicazioni:rivistaDi prodotto:ID37128 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID37128 .
