ASSESSMENT OF DEPOSITS ON ENGINE HEAD IN SINGLE CYLINDER DIESEL ENGINE

The purpose of this experimental work is to examine deposit accumulations on engine heads by employing a single-cylinder water-cooled diesel engine. In this study, the tested fuels selected are DF, DF95UCO5, and DF65UCO20Pn15. Because it has the largest fuel oxygen percentage, the lowest cetane number, DF65UCO20Pn15, has the longest explosion delay and the shortest burning time. Measurements were made of engine heads and compared to emulsion fuels. The same locations also saw the application of scanning electron microscopy for a qualitative investigation. The investigation's conclusions were supported by visual inspection, which showed some deposition on engine heads while using all fuels. The study found that DF95UCO5 formed more carbon deposits on the engine head than DF65UCO20Pn15 and DF when SEM and EDS were used
