生物資源由来燃料を用いたディーゼルエンジンの運転条件が排出ガス特性に及ぼす影響

抄録

Thermal efficiency and exhaust gas characteristics of Diesel engines are greatly affected by the combustion state. On the other hand, Bio Diesel Fuel (BDF) contains a lot of oxygen, but the ignitability is inferior because the viscosity is high compared with gas oil. However, the previous researches found out that while gas oil and BDF are different fuel properties, the operating conditions to lose the remarkable difference of the thermal efficiency and the exhaust gas characteristic when using these with Diesel engines. In this research, operation conditions were examined while paying attention to the exhaust gas characteristic that changed by the combustion state by the performance examination of the diesel engine using BDF.
