Abstract

Biodiesel is a renewable energy that has the fuel properties almost similar to conventional diesel fuel. Biodiesel production through transesterification process, involved a chemical reaction to separate the glycerol from the waste vegetable oil. Biodiesel had been undergo seven types of fuel testing properties which are flash point, (ASTM D93), kinematic viscosity (ASTM D445), water content (EN ISO 1293) and the others. This report was focused on the tribological properties of the biodiesel blends where there are four different group of studies, B100, B5, B10 and B20. There are three types of tribological properties that was considered which are coefficient of friction (COF), flash temperature parameter (FTP) and wear scar diameter (WSD). This experiment will be carried out using four ball tester (FBT) to determine the tribological properties of biodiesel. Meanwhile, Inverter Microscope was used to define the average wear scar diameter. The increment of biodiesel concentration to the diesel fuel leads to the decrement of COF value even at higher load. The WSD slowly decline at 40 kgF and 15 kgF of load, as the reduction of the biodiesel concentration. The B100 shows the excellent lubricant in term of COF, nevertheless it have the greater value of the WSD. B20 observed to be a good lubricity compared with the biodiesel blends due to its low value of COF and WSD, as well as high in FTP under both type of loads
