Engine Performance Characteristics of a Compression Ignition Engine Fuelled by Traditional Diesel and Waste Cooking Oil

Abstract

This research presents a comparison of the test engine's performance characteristics fuelled by diesel and waste cooking oil synthetic diesel (WCOSD). Commercial diesel (CD) fuel used in this research was commercial diesel in the market; meanwhile, WCO was manufactured from cooking waste product using Catalytic Cracking Method. The synthesizing process known as Catalytic Cracking Method at pilot scale level using non-food oil such as waste cooking oil to manufacture biodiesel fuel oil in place of diesel with a stable energy output. The results of this research showed that it can be concluded that the engine torque with WCO drop from 1.9 Nm to 5.4 Nm at all speed while the BSFCs drop at almost speed at full load condition compared to that of CD. The BTEs of the engine fuelled with WCOSD are higher than that of the engine fuelled with CD at almost engine speed at full load. The result of this research is the foundation for using WCO in worldwide application.
