Abstract
Considering the amount of waste plastics has risen significantly, energy may be extracted from it. Not only is it possible to dispose of waste plastics by converting them to fuel, but it is also possible to extract energy from them. Our research is motivated by the prospect of using waste plastics as a source of energy through waste plastic pyrolysis oil (WPPO). The innovation of this research is that it will assess the efficiency of plastic pyrolysis oil derived from Low-Density Polyethylene (LDPE) on a Thermal Barrier Coated (TBC) piston engine. The incremental ratio of WPPO to pure diesel with the addition of diethyl ether (DEE) was determined and its output and exhaust emission standards were evaluated using a direct injection single cylinder low heat rejection diesel engine. The results for the WPPO blends were promising as with TBCW20DEE10 demonstrating a 5 to 15% increase in carbon monoxide under different load conditions. TBCW20DEE10 confirmed a greater reduction of hydrocarbons varying from 5 to 12 %. At half load condition, TBCW20DEE10 emits approximately 3.5 % less unit of smoke.

The world’s use of plastics is increasing daily, and the world is yet to discover a suitable substitute
Consumable plastic materials accumulate during daily operations, and the world is yet to develop a better method of disposing of non-biodegradable plastics
The primary purpose of this study is to demonstrate the feasibility of using waste plastic pyrolysis oil (WPPO) as an alternate energy source in the automotive industry
Summary
The world’s use of plastics is increasing daily, and the world is yet to discover a suitable substitute. Disposal of plastic products after use poses a significant risk. The most environmentally friendly way to dispose of waste plastics is to turn them into energy fuel. Rajan et al (2016) examined the efficiency and combustion characteristics of a diesel engine fueled by recycled plastics. The results indicated that the engine would run on waste plastic oil and its mixtures without modification can be used as a substitute for diesel fuel. Gungor et al (2015) analyzed waste plastic oil and contrasted it to fuel in a multi-cylinder diesel engine. Thermal performance significantly decreased when pure WPPO was used. The concentrations of carbon monoxide and nitrogen oxides increased
