Experimental Investigation of Engine Characteristics Using Biomedical Waste Pyrolytic Oil at Different Injection Pressures
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 8
Abstract
The main aim of this study is to investigate the effect of injection pressures on emission and performance analysis of biomedical waste pyrolysis oil, plastic waste oil and its blends with diesel using diesel engine. This research describe a comparison of the use of pyrolysis oil i.e plastic pyrolysis oil which is extracted from biomedical wastes and normal diesel oil for different injection pressures in the assessment of engine performance, characteristics, and feasibility analysis. .The parameters like brake thermal efficiency, brake specific fuel consumption, and exhaust emissions like NOx, CO2, CO, and mass fraction burned., were considered for comparing the performance of pyrolysis oil in various proportions and with varying loads at two injection pressure i,e 180 and 200 bar. The initial experiments were done at injection pressure of 180 bars, later the injection pressure was changed to 200 bars. It was observed that the brake thermal efficiency increased as the injection pressure increased from 180 bars to 200 bars. The NOx emission reduced as the injection pressure was increased to the CO emission gradually decreases as the injection pressure increased. It was observed that addition of oxygenates had improved the combustion process and reduced the emissions. The investigation revealed that blending of DEE with plastic oil increases the Cetyane rating which is superior to neat diesel. The economic analysis shows that the pyrolysis oil is able to replace diesel in terms of engine performance and energy output if the price of pyrolysis oil is not greater than 85% of diesel oil.
