The Use Of Used Oil From Treatment With Absorption and pyrolysis As A mixed of Diesel Oil To Performance Diesel Engine

Abstract

An adsorption process is able to filter out solid objects in used oil such as dust, scrap metals and charcoal from burnings so that the color of used oil is not too dense even though it is still black. The pyrolysis process can improve the color of used oil so that it becomes clear yellow like new oil, even though it does not meet diesel engine fuel criteria. The mixture of used oil from the pyrolysis process with diesel fuel still meets the characteristics of diesel fuel because the results are close to the characteristics of diesel fuel. Research results show that the mixture of used oil in diesel engine fuel if used as fuel can save 10% of the fuel because the power and efficiency when compared with pure diesel fuel is almost the same, but the exhaust emissions are large if the percentage of used oil in fuel is increased
