Improvement of engine performance, combustion and remarkable reductions in NOx, CO and unburned HC emissions fuelling with mixed plastic pyrolysis oil and oxygenated additives

Global emissions from the transportation sector are one of the reasons for climate change. This study aims to use waste-plastic-derived pyrolysis oils in a diesel engine to reduce exhaust emissions and improve engine performance. Pyrolysis oils were derived from waste plastics and oils were tested in a diesel engine effectively by blending with diesel and oxygenated additives. The experimental results were validated with simulation results. The key findings are the remarkable reductions in carbon monoxide (CO, 74.4 %), unburned hydrocarbon (UBHC, 62.1 %), and nitrogen oxide (NOx, 18.96 %) emissions without deteriorating engine performance at all engine operating conditions.
