Effective utilization and optimization of waste plastic oil with ethanol additive in diesel engine using full factorial design

Abstract

Hydrocarbons, which are found in plastic, are an excellent energy source due to their high energy density. The disposal of plastic waste presents significant energy saving and recovery opportunities. The purpose of this study is to determine how much energy can be recovered from waste plastics as a possible alternative fuel source for cars. This research aims to assess the performance of waste plastic pyrolysis oil (WPO) generated by polyethylene pyrolysis. Ethanol is an appealing alternative fuel since it is made from renewable bio-resources and works as an oxygenated fuel in diesel engines, allowing for emission reductions. Three different percentages of WPO were combined with ethanol to create a tertiary fuel blend. This research examines the performance and emission requirements of a single-cylinder direct injection diesel engine. With diesel, D70W20E10′s specific fuel consumption reduces by about 7.5 %. Carbon monoxide emissions from D70W20E10 were about 6.5 % lower than diesel and 13.5 % lower than hydrocarbon at various loadings. The most optimum running condition was further examined using the Full Factorial Design method.
