Abstract
Plastics usage are increasing day by day and we are yet to get a credible replacement for the same material. The disposal of after use plastic poses a major challenge and best disposal is converting the same as fuel. The major of the advantage of conversion to fuel is not the only disposal but also enable energy to be derived from the disposal of after use plastics. Used plastics can be converted to alternate energy fuel for the diesel engine by the catalytic pyrolysis. With consideration of brake thermal efficiency and running reliability and the consistency, diesel engines are the most suitable for altered with pyrolysis oil. Besides, many oxygenates have higher cetane values and their addition with diesel fuel results in the increase of overall cetane number which in turns leads to higher combustion rate and enhanced combustion with lower emissions. In this research paper, the incremental ratio of Waste Plastic Pyrolysis oil (WPPO) was blended with a constant 5% of diethyl ether as cetane improver and with diesel. A direct injection single-cylinder diesel engine was used for the investigation of engine performance and exhaust emission norms. The results were studied and compared for compatibility with diesel alternative.
