Modification of Engine Diesel for The Use Waste Lubricant Oil as an Alternative Fuel
Waste lubricant oil is a residue of pure oil that comes from many kind of industrial activities and engine means. After waste oil is converted to fuel without special treatment, waste oil can be used as fuel for the internal combustion engine. The engine diesel is modified in the fuel filter system and the addition of the fuel pump. Filter system use fuel filter which is positioned parallel with two filtering stages. In the first stage the filter is given a magnet to pull the iron powder that is contained on the oil and the second filter has the function to filter out of the whole of the dirt that causes the nozzle to clog. This Fuel Pump serves to supply waste lubricant oil into the fuel injection system. From the experimental results showed that the value of volumetric efficiency in diesel fuel reached 51.6316% and the value of volumetric efficiency in waste lubricant oil reached 51.6335%.
