The cellulosic liquefaction fuel (CLF) is made from woods by direct liquefaction process and CLF can be mixed with diesel fuel when fuel temperatures are higher than 30 [℃]. The purpose of study is to analyze the ignition characteristics of CLF on cold start condition. In cold start test, the engine is started without warm-up and the transient performance is measured. CLF is mixed with diesel fuel and the blended ratio of CLF is changed, and tests are made at full load injection setting. The blended fuel can be ignited and burned immediately after the engine is started, when the blended ratio of CLF is up to 20 [wt%]. The crank angle at ignition delays and the maximum combustion pressure decreases as the blended ratio of CLF increases because CLF includes a lot of aromatic hydrocarbons. However, the ignition delay and combustion pressure reduction are gradually improved as the engine is warmed-up.
