Abstract: Esterified bio-diesel oil is normally used as blend oil of 3% that and 97% diesel fuel in Korea.
Since specifics of it is similar to that of diesel fuel, availability of non-esterified bio-diesel oil that has a lower expenses of manufacturing is worthy of attention. However, bio-diesel oil has a demerit which it emits typically more NOx emission than diesel fuel. In this study, characteristic tests using blending oil with 95% gas oil and 5% bio-diesel oil were achieved at lower common rail pressure in order to improve this demerit. It was noticed that non-esterified bio-diesel oil has more similar characteristics to diesel fuel than esterified bio-diesel oil and it emits more NO emission by fuel NO mechanism.
Key Words:Esterified, Non-esterified, Lower Common Rail Pressure, Electric Control System, Diesel Engine
