Analysis of Performance and Emissions of an Automotive Euro 5 Diesel Engine Fuelled with B30 from RME and JME

摘要: The effects of using a B30 blend ultra low sulphur diesel and two different Fatty Acid Methyl Esters (FAME) obtained from both Rapeseed Ester (RME) Jatropha (JME) in Euro 5 small displacement passenger car engine on full load performance part emissions have been evaluated this paper. In particular the torque were firstly analyzed, for standard ECU calibration (i.e. without any special tuning fuel characteristics) specifically adjusted by properly increasing injected quantities to compensate lower LHV B30: with latter, same levels measured under operation could be observed too, smoke levels, thus highlighting potential maintaining level while achieving substantial benefits. Moreover, 30% vol. blends brake specific consumption engine-out exhaust (CO2, CO, HC, NOx smoke) also at 6 operating conditions, representative New European Driving Cycle. Both (change accelerator pedal position) (adjustment energizing time main injection) 4% average rise consumption, mass basis, conversion efficiency CO2 emissions. A noticeable increase CO HC noticed, along significant decrease when calibration, considerable emission reduction
