生物資源由来燃料と軽油の混合燃料がディーゼルエンジンの排ガス特性に及ぼす影響

抄録

Bio Diesel Fuel (BDF) contains a lot of oxygen, but the ignitability is inferior because the viscosity is high compared with gas oil. However, previous research has found that while gas oil and BDF have different fuel properties, use of these under operating conditions with diesel engines eliminates the drastic differences in thermal efficiency and exhaust gas characteristics. Therefore, the purpose of this study is to grasp the effects of oxygen in fuel in the combustion process of diesel engines. To this end, engine performance testing using mixed fuels of BDF and gas oil with different oxygen content rates was performed. The results clarified that using fuel with a moderate mix of BDF and light oil improves the exhaust gas characteristics of the diesel engine compared to using BDF alone.
