Abstract

With the increment of usage of plastic materials, the use of polyethylene (PE) all over the world is also increasing. The great amount of PE usage results in a huge amount of PE waste. These huge amounts of PE wastes are generating environmental problems due to their non-degradable properties. But, PE wastes can be converted into liquid fuels for both economic and environmental benefits. In this experimental study, the conversion of PE wastes into diesel fuel and influence of the polymer-based fuels on the performance and exhaust emission of diesel engine was investigated. The conversion of PE wastes was carried out by utilizing the thermal pyrolysis process. The blends of the PE waste based fuel with diesel fuel were tested with three different ratios (5%, 10%, and 20%) in an unmodified direct injection diesel engine at full load condition. In general, engine performance and exhaust emission values of the blend fuels were similar to that of diesel fuel. Specific fuel consumption (SFC) values of the blend fuels slightly increased depending on the ratio of PE based fuel in the test fuels. The carbon monoxide (CO) and oxides of nitrogen (NO)x emissions of the blended fuels values showed an increasing trend as compared to the values of diesel fuel.
