Experimental study of diethyl ether addition on the performance and emissions of a diesel engine

Abstract

ABSTRACTRecently investigations were carried out on the utilisation of light fraction pyrolysis oil (LFPO) in diesel engine, which was obtained from a tyre recycling plant. The 40LFPO blend, which comprised 40% LFPO and 60% diesel composition gave better performance and lower emissions than the blends containing 20LFPO, 60LFPO and 80LFPO. The ignition delays of the blends were longer than that of diesel fuel, because of their lower cetane numbers. The aim of this investigation was to study effect the adding small quantities of Diethyl ether (DEE) whose cetane number is 125, to 40LFPO on the engine behaviour in terms of performance parameters and exhaust emissions. The percentage of DEE was varied from 1% to 4% in steps of 1% on a volume basis. The results of the performance and emission parameters of the engine run on the 40LFPO-DEE blends were evaluated, compared with the diesel operation of the same engine and presented in this article.
