Analysis on Tribological Characteristics of Waste Ayurvedic Oil Biodiesel Blends using Four Ball Tribometer

Abstract : Tribology related problems in an engine give challenges to the automobile sector. To minimize the issues raised by diesel fuel, the biodiesel gains a vertical attention by the researchers. Especially, the waste oils will lead a high pollutant material to the environment and it needs a proper procedure to disposal. In this present study it is aimed to investigate the friction and wear characteristics of Waste Ayurvedic Oil (WAO) biodiesel blends by varying the applied load in a four ball wear test Tribotester. The investigations of fuels were WAO biodiesel blends (B10, B15 and B20) and diesel fuel was analysed with test conditions viz: load 40Kg and 80Kg, constant temperature 75°C, duration: 300 sec, sliding speed: 1200rpm for all the tested fuels. For the given experimental conditions more wear scar diameter were observed for diesel than WAO biodiesel blends for both the loads. The coefficient of friction and frictional torque were absorbed less with WAO15 for both the loads than other blended fuels and diesel fuels. The worn surfaces of the steel balls were examined by a Scanning Electron Microscope (SEM). The morphology image results showed that minimal friction, wear and smoother surface were absorbed for all the biodiesel concentrations than the diesel fuel.
