Driven by dwindling oil resources and rising energy demands, researchers are exploring ways to convert waste products into high-quality fuels that can replace fossil fuels. Plastic waste, a growing concern, can be a valuable resource. This study investigates the potential of fuel oil (FO), derived from waste plastic (lowdensity polyethylene), as a fuel source. Fuel oils were produced from low-density polyethylene at 340°C and 450°C, respectively. The properties of these oils and their blends with commercial diesel were analysed using the American Society for Testing and Materials (ASTM) Method. Engine tests were then conducted using fuel oil and compared to diesel. The blend also resulted in slightly higher carbon dioxide (CO2), oxides of nitrogen (NOx), and unburned hydrocarbons (HC). However, there is a similarity in brake thermal efficiency, specific fuel consumption, and carbon monoxide emissions of fuel oil and diesel. Notably, adding diesel to fuel oil improves engine performance. The fuel properties of the fuel oil obtained from LDPE were comparable to diesel, suggesting potential direct use as engine fuel or refinery feedstock. The engine runs smoothly and is conducted up to a 30% blend, with improved brake thermal efficiency and lower fuel consumption than pure diesel. This highlights the need for further research on fuel fractionation or engine modifications to optimise performance and minimise emissions [ABSTRACT FROM AUTHOR] |
