Effect of plastic oil-methanol blends operated on petrol engine performance and exhaust emissions

ABSTRACT

Energy is becoming a vital and crucial parameter in many technical, commercial and self-development sectors of an individualistic in any countries. In this context, fossil fuels are devaluing and their costs are rising and hovering. While generating energy from the existing fossil fuels is not alone economically infeasible but also provoke many sensitive environmental issues. Along with emissions from automobile sector, one of other culprits in ecosystem is disposal of waste plastics. To meet the acute energy needs with eco-balance is utilising plastic oil as functional fuel to run the engines. This research paper presents the experimental investigations on multi-cylinder petrol engine operating with 10% and 20% of plastic pyrolysis oil with and without methanol additive at 5% volume basis blended with petrol. The experimental results observed that the engine brake thermal efficiency was improved 7.9%, 18.6% and HC emissions were 25.31%, 5.6% controlled with the 20PPO5M compared to petrol fuel and 20PPO fuel operated at full load conditions.
