The cellulosic liquefaction fuel (CLF) was made from woods by the direct liquefaction process. The compression ignition did not occur when neat CLF was supplied for diesel engines, because CLF mainly consisted of aromatic compounds. CLF could not be completely mixed with diesel fuel, however, CLF and diesel fuel could be blended when FAME was mixed as a solvent. Coconuts-oil methyl ester (CME) was used and 5 wt% that was allowed mixing ratio to diesel fuel in JIS was mixed. To clarify a desirable CLF fraction for diesel engines, CLF was divided into two fractions by the fractional distillation: 473 to 523 K (CLF1), 523 to 573 K (CLF2). The purpose of this study is to analyze ignition characteristics and performance of diesel fuel-CME-CLF blends and the tested weight mixing ratio of CLF were 5, 10, 15 and 20 wt%. It was confirmed engine could be stably operated for both CLF1 and CLF2 mixed fuels.
