A Research on Specific Fuel Consumption and Emission Characteristics from Diesel Engines Used Palm Biodiesel

Biofuels are mainly composed of bioethanol and biodiesel, biogas. In particular, biodiesel can completely replace diesel fuel based on similar properties of cetane value, specific calorific value ... and its environmental friendliness. Biodiesel is a liquid biofuel with similar properties and can be used as a substitute for conventional diesel oil. Tests using biodiesel (BDF) on internal combustion engines have also been conducted. The results of these tests show that BDF can be used on engines at any rate mixed with diesel fuel without changing engine structure. In addition, using BDF reduces harmful emissions into the environment such as CO, SO2, PM, CxHy .... [9, 10]. Emission factors of engine pollutants, combustion efficiency of fuel and engine power depend on BDF mixing ratio in fuel and engine load. Study to assess engine fuel consumption and ordinary emissions of palm oil biodiesel fuel (BDF palm oil) used on diesel generators. The experiments were performed at no-load and high-load mode with mixing ratios of BDF palm oil and diesel fuel (0%, 5%, 10%, 15%, 20%, 50%, 100% are equivalent to B0, B5, B10, B15, B20, B50, B100). Results showed that specific fuel consumption increased as volume of BDF palm oil increased in fuel. In idle mode, compared to diesel fuel, fuel consumption increased by 1.32%; 1.8%; 2.8%; 3.74%, 5.61%; 6.54% corresponding to B5, B10, B15, B20, B50, B100. In high load mode, fuel consumption increased by 1.51%; 1.86%; 2.18%; 4.78%; 5.36%; 6.76% corresponding to B5, B10, B15, B20, B50, B100 compared to diesel fuel
