Experimental Studies on a DI-CI engine using blends of diesel fuel with Plastic diesel derived from Plastic Waste at 250 bar injection pressure

Abstract

Replacement (partial) of fossil fuels with alternate fuels has been set as a target worldwide to reduce greenhouse effect and energy dependence as well as to improve economy. Emissions from transportation engines are considered to greatly contribute to greenhouse gases (carbon dioxide) release. In the present day scenario emissions associated with the exhaust of automobiles resulting in global warming is a major menace to the entire world and also detrimental to health. An experimental investigation is conducted to evaluate the use of Plastic diesel derived from plastic waste in a direct injection (D.I), C.I engine. The tests are conducted using each of the petrol diesel and Plastic diesel at 250 bar fuel injection pressure, with the engine working at Constant speed. Fuel consumption, and exhaust regulated gas emissions such as nitrogen oxides, carbon monoxide and total unburned hydrocarbons are measured. The differences in the measured performance, combustion and exhaust emissions from the baseline operation of the engine, i.e., when working with petrol diesel fuel and the plastic diesel are determined and compared. The experimental results show that blends of plastic diesel, with diesel lowers the viscosity and leads to good improvement in brake thermal efficiency.
