- 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 25% of pyrolised waste plastic oil with bioethanol-diesel blends, 20% of pyrolised waste plastic oil with biobutanol-diesel blends and 35% of pyrolised waste plastid oil with biobutanol are closer to that of diesel. These three blends are being tested for performance in three compression ratio 16:1, 17.5:1 and 19:1 under various brake power conditions. The engine tests depict that 19:1 compression ratio is found to be suitable for fueling these fueling these blends by comparing the thermal efficiency produced. Further, these blends are tested for combustion and emission characteristics using 19:1 compression ratio for five brake power conditions. 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 17.5:1 compression ratio. At low brake power conditions, these blends produce marginally higher hydrocarbon and carbon monoxide emissions compared to that of diesel.
