Abstract

Recently, many pilot pyrolysis plants have been installed in different parts of the world to recycle waste automobile tyres. The light fraction of pyrolysis oil (LFPO) obtained in a pilot plant has properties better than those of the crude tyre pyrolysis oil (TPO) which is obtained in a laboratory level pyrolysis plant. This paper presents the determination of cetane number of the LFPO and its diesel blends, using a correlation. They were then used as fuels in a small powered, single cylinder, direct injection (DI) diesel engine to establish the results of combustion, performance and emission parameters of the engine. The cetane number of the LFPO and its blends were observed to be lower than those of diesel at all loads. The combustion of the LFPO-diesel blends started little later, and its duration was longer for the LFPO-diesel blends compared to that of diesel fuel at full load. The ignition delay was also found to be longer for all the blends tested in this study at full load. [Received: August 22, 2014; Accepted: January 1, 2015]
