Performance and Emission Studies of a Naturally Aspirated Diesel Engine

S. Murugan, Kapura Tudu, and S. K. Patel
Abstract—Tyre recycling is one of the attractive solutions considered today, for the waste management of automobile waste tyres. In a practical tyre recycling plant that follows vacuum pyrolysis, light fraction pyrolysis oil(LFPO), heavy fraction pyrolysis oil(HFPO), non-condensable gas, carbon black and less fraction of steel wire are produced. Early investigations carried out by the authors reveal that a blend comprising 60% light fraction tyre pyrolysis oil(LFPO) and 40% diesel fuel(40LFPO) in it can be used an optimum blend percentage and used as an alternative fuel in a single cylinder, four stroke, direct injection(DI) diesel engine. Although the engine was able to run with the 40LFPO blend, the ignition delay for the 40LFPO blend was found to be longer than that of diesel operation in the entire load spectrum. In this study, the effect of adding small quantities of an ignition improver with the 40LFPO on the performance and emissions of a single cylinder, four stroke, air cooled, direct injection (DI) diesel engine developing power of a 4.4kW at a rated speed of 1500rpm was studied. For this purpose, Diethyl ether, an ignition improver (DEE) in small quantities from 1-4% on volume basis was blended with the 40LFPO accordingly. The blends were denoted as X1, X2, X3 and X4 where X indicates the mixture of 40LFPO and DEE and the numeric value indicates the percentage of DEE in it. The results of the performance and emissions of the engine run on different DEE blends and compared with those of diesel operation presented in this paper.
