The cellulosic liquefaction fuel (CLF) was made from woods by direct liquefaction process. CLF was divided into three fractions: 200 to 250[℃] (CLF1), 250 to 300 [℃] (CLF2) and 300 [℃] or more (CLF3) by the fractional distillation. Each CLF ingredient was mixed with coconuts oil methyl ester (CME) to provide engine because they can not be mixed with diesel fuel. All test fuels could be burned by diesel engine, when the mixing ratio of CLF was up to 15 [wt.%]. In case of mixing ratio of CLF 15 [wt%], for CLF1 and CLF2, thermal efficiency and brake mean effective pressure were almost equal to those of CME. The crank angle at ignition delayed as mixing ratio of CLF increased, however when the engine was warmed up, the ignition characteristics was improved. CLF1 showed good ignitability compared with other CLFs because CLF1 had low distillation range and included volatility components.
