Abstract: The current energy challenges in agriculture, industry, and transportation are aggravated by insufficient liquid petroleum fuels, strained by rapid depletion, and higher demand in the international market. Existing environmental pollution due to higher fossil fuel consumption, certainly draws the attention of many researchers to identify a better alternative fuel concerning engine efficiency and exhaust emissions. Waste plastic oil (WPO) derived by thermo-catalytic pyrolysis is found to be a promising alternative fuel due to it's similar fuel properties to diesel. WPO contains long-chain hydrocarbons and high-molecular-weight aromatics which can be eliminated by fractional distillation, resulting in the production of distilled waste plastic oil (DPO). Ethanol is added in addition to DPO in the diesel fuel mixture in order to improve combustion for better performance and reduce emissions. The current study focused on the preparation of homogenous fuel mixtures (DPO/ethanol/diesel) to evaluate it's engine efficiency and exhaust emissions as compared to pure diesel and confirmed that it has the potential to be an alternate fuel for the CI engine. Test engine trials were performed to determine the potential engine characteristics, for instance, thermal efficiency, specific fuel consumptions, and exhaust temperature, by using various fuel mixtures (80D10DPO10E, 70D15DPO15E, 60D20DPO20E, 50D25DPO25E) under different loading conditions of the test engine. Major pollutants including unburned hydrocarbon, carbon monoxide, and nitrogen oxides were measured by a standard emission analyzer. The BTE was increased by 3.7%, and the BSFC was 16.67% less for the 60D20DPO20E mixture so as to diesel at full load. CO emission was found to comparatively increase at higher concentrations and decrease at higher loads. Compared to diesel, the NOx and HC emission were shown to be lowered at low loads and increased at higher loads. The study concluded that the fuel mixture of 60D20DPO20E showed the best engine performance and reduced emissions as compared to diesel. [ABSTRACT FROM AUTHOR]
