Biodiesel fuel ; BDF is a renewable diesel fuel substitute that can be made by esterfication process combining any biogenic oils from plants such as rapeseed oil or recycled cooking oils with an alcohol such as methanol or ethanol and catalysts. BDF can help reduce greenhouse gas emission ; CO_2. Objective of this study is to experimntally clarify the effect of raw materials which processed BDF and injection systems on combustion and emission characteristics by using a DI diesel engine. Engine tests were carried out using neat BDF and conventional injection pump and high-pressure injection system. From the experiments, BDF processed from recycled rapeseed oil is effective to reduce nitrogen oxides and smoke emissions. Thermal efficiency is same with petroleum diesel fuel ; JIS #2. And at this BDF, the effect of an increase in injection pressure on emission characteristics is contrast with that at BDF of recycled coin oil.
