Operating conditions such as engine speed and load of diesel engines change the combustion state. In addition, the thermal efficiency and PM emission characteristics 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 PM exhaust characteristic when using these with Diesel engines. In this research, operation conditions were examined while paying attention to the PM exhaust characteristic that changed by the combustion state by the performance examination of the diesel engine using BDF.
