摘 要：Three sunflower oil/diesel blends and pure sunflower oil were tested in a CI engine using the manufacturer’s settings,two altered injection timings（IT±2o CA） and injector protrusions（IP±0.5mm）.36 Fuel-IT-IP configurations were completed,plus the reference run with diesel.A life cycle analysis（LCA） was conducted and fossil CO2 was *** configurations were compared using analytical hierarchy process（AHP） that was applied for three cases:*** on engine performance,*** driven and *** situation between the first *** case was overviewed using two perspectives:either with CO2 values measured in the tests or the CO2 calculated by the LCA;it was shown that all cases,in both perspectives,gave similar results in the Fuel-IT-IP configurations ranking with minor ***,the results were significantly different when comparing the two *** LCA CO2 values favoured high oil content fuels ranking them in the first *** was graded very *** IT was positive translated in covering most of first *** did not give a clear influence trend on final ranking,as IT was dominant in engine performance and *** fuels had disadvantages（*** BSFC,high NOx values）,but they were overcome by the advantages（*** torque,lower CO2） to receive higher ranking position.
