| Summary: | Further enhancing the oxygen content (OC) of the conventional B5 palm oil biodiesel is the key to attain greener emissions in future. Diethyl succinate (DES) and 1-octanol (OCT) is designed to blend with B5 to address this issue. In this study, the optimum binary and ternary blend (with higher OC) of B5 with DES and/or OCT is obtained using a computer-aided decomposition-based optimisation. Subsequently, the engine performances including fuel efficiency: brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) and emissions of nitrogen oxides (NOx), carbon monoxide (CO) and un-burnt hydrocarbon (UHC) of these optimum blends are evaluated experimentally. Ternary blend of B5 with DES and OCT could attain higher OC than binary blends with satisfied target fuel properties. The designed optimum blends generally have greener emissions than B5 while having similar fuel efficiency with B5. T1 ternary blend (B5 = 70.0 %; OCT = 24.1 %; DES = 5.9 %) appear as the most promising green diesel blend owning to its greener emissions and similar fuel efficiency with B5. |
