Experimental Investigation of Performance of Variable Compression Ratio Engine Fueled with Pyrolised Plastic Oil and Bio Alcohols 2022-01-0605

Waste Plastics are the main barriers in the rain water percolation into the ground which enhances the improvement in the water table. This study utilizes pyrolised waste plastic oil along with diesel-bioethanol, diesel-biobutanol and butanol to fuel variable compression ratio engine. Initially, various proportions of pyrolised waste plastic oil has been blended with bioethanol-diesel blends (containing 15% of bioethanol), biobutanol-diesel blends (containing 20% biobutanol) and Biobutanol and tested for solubility under 25°C followed by property testing as per the American Society of Testing Materials. The results of the property resting are compared by considering diesel fuel as the base fuel. The results indicate that properties of the blends containing 21% of pyrolised waste plastic oil with bioethanol-diesel blends, 15% of ethanol blended with diesel fuel, and 12% of pyrolised waste plastid oil with 88% of biobutanol are closer to that of diesel fuel. Results indicate that the fuel blends produce peak cylinder pressure, net heat release rate, ignition delay, emissions of oxides of nitrogen and smoke when fueled in engine are found to be competent with respect to diesel readings at standard operating parameters. At low brake power conditions, these blends produce marginally higher hydrocarbon and carbon monoxide emissions compared to that of diesel.
