THE EFFECTS OF MANGO BIODIESEL SEED OIL TO DIESEL ENGINE PERFORMANCE

The high reliance and demand for non-renewable energy push the need for alternative renewable resource of energy. In this study, a biodiesel made from mango seed oil was investigated to understand its viability as substitute to commercial pure-petrodiesel and palm oil biodiesel. The extraction of mango seed oil was done by using Soxhlet method. The extracted oil was combined with traditional diesel fuel by 10% of its total weight of mixture to create mango biodiesel seed oil B10 (B10). The B10 was tested for its fuel characteristics together with pure-petrodiesel and palm oil biodiesel. The fuel characteristics test results indicated some advantages of mango biodiesel compared to the commercial fuels. Further study on the engine performance of the fuels were conducted by utilizing water brake dynamometer. The engine performance results show B10 has overall better power, torque, BMEP, SFC and thermal efficiency compared to pure-petrodiesel and palm oil biodiesel. Both investigations of fuel characteristics and engine performances corroborate the use of mango seed biodiesel as substitute for pure-petrodiesel (solar) and palm oil biodiesel (biosolar).
