Experimental investigation of performance, emission and combustion characteristics of a CI engine fuelled by blends of waste plastic oil with diesel

Abstract

ABSTRACT In today’s society, waste plastic recycling has gained a lot of traction. The utility of energy has increased as a result of the significant increase in population expansion. Traditional fuels, such as petroleum and its byproducts, are finite resources that are insufficient to address fuel scarcity. In this scenario, an endless, low-cost, and readily available alternative fuel is required. The most acceptable solution is to extract fuel oil from waste plastics. Modification of waste plastics to productive fuel oil in a pyrolysis reactor is out through in this experimental investigation. The physio-chemical properties of plastic oil obtained in a pyrolysis reactor are compared to ASTM standards at the matching interval. The viscosity has increased, and carbon residue can be seen. At the pyrolysis reactor, diesel (80%) with waste plastic oil (20%) and diesel (60%) with waste plastic oil (40%) are combined in a volume ratio of 80% to 20%. Combustion analysis is performed in the diesel engine’s ignition chamber. The results indicated that employing waste plastics oil-diesel fuels in a diesel engine moderated thermal efficiency by 2.2% when associated to using pure diesel fuel at CR17.5. Furthermore, the peak rate of pressure rise, peak cylinder pressure, and smoke emission were all dime stored by 0.72%, 8.1%, and 1.5%, respectively. In analogy with diesel, waste plastic oil has slightly higher values. Even so there is additionally specific fuel consumption. The physic-chemical properties of waste plastic oil have superior influence on combustion besides performance characteristics.
