The cellulosic liquefaction fuel (CLF) is made from woods by direct liquefaction process. CLF was divided two fractions by distillation: these were 200 to 250℃ (CLF1) and 250 to 300℃ (CLF2). Coconuts-oil methyl ester (CME) was used to mix CLF and diesel fuel. The purpose of this study is to analyze the ignition characteristics and performance of CLF-CME-diesel fuel blends and to clarify the most desirable CME mixing ratio for practical use. Tested weight mixing ratios of CME and CLF to diesel fuel were 0, 5, 10, 15 and 20 wt.%. When CLF1 and CLF2 were mixed, the crank angle at ignition delayed, however the ignitability was improved in high load operating condition. The engine performance and exhaust gas emission were hardly influence by mixing ratio of CME. Therefore, the CLFl-CME-diesel fuel blends which included CME 5 wt.% was the most suitable fuel for practical use to the diesel engine.
