Engine Fuel Production from Waste plastic Pyrolysis (WPO) and Performance Evaluation in a CI engine with Diesel Blend

Plastic waste disposal throughout the world is creating problems and degrading the environment.Today transportation and electric power generation in rural areas mostly depend on fossil fuels. Such extensive use of fossil fuel is resulting in depleting it at analarming rate. Hence, it is required to produce an alternative fuel to keep them running as well as minimizing waste disposal. Waste plastic pyrolysis oil is identified one of such good alternative. In this study, waste transparent plastic, used for packaging, is used for the conversion of fuel through pyrolysis process.It was observed that yield of plastic oil was approximately 65-70 %. However, a liquid yield affects heating rates and heat loss patterns in the reactor system. This paper also presents the effect of waste plastic pyrolysis oil in a diesel engine at various compression ratios with different load and blending with pure diesel (pure diesel, 10%, 20%, 30%, 40%) at constant engine revolution. The performance characteristics include engine brake power, brake thermal efficiency, specific fuel consumption and exhaust emissions. Experimental investigation shows that Plastic oil can be used to save the 40% diesel without loss of power, and its trend do not differ with variation in compression ratio.
