EFFICIENT USE OF USED COOKING OIL IN A DIESEL ENGINE BY ADDING 1-BUTANOL TO REMOVE DEBRIS

This experiment uses a single-cylinder, water-cooled diesel engine to investigate deposit accumulations on engine heads. The tested fuels chosen for this investigation are DF, DF95UCO5, and DF65UCO20Bu10. The lowest cetane number, DF65UCO20Bu10, has the shortest burning time and the longest explosion delay due to its highest fuel oxygen percentage. Engine heads were measured and contrasted with emulsion fuels. Scanning electron microscopy was also used for a qualitative examination at the same sites. Visual inspection, which revealed some deposits on engine heads when using all fuels, corroborated the investigation's findings. Using SEM and EDS, the study discovered that DF95UCO5 produced more carbon deposits on the engine head than DF65UCO20Bu10 and DF.
