Study on effects of Alumina nanoparticles as additive with Poultry litter biodiesel on Performance, Combustion and Emission characteristic of Diesel engine

Abstract

In the recent research, as a result of depletion of world petroleum reserves, considerable attention has been focused on the use of different alternative fuels in diesel engines. The present work aims to ensure the possibility of using poultry litter oil biodiesel obtained from wastes of poultry industries as an alternative fuel for diesel in a compression ignition engine. In this study, biodiesel is obtained from poultry litter oil by acid and base catalyzed transesterification with methanol when sulfuric acid and potassium hydroxide as catalyst. The experimental work is carried out in a CI engine using poultry litter oil B20 biodiesel blend and B20 biodiesel blend with 30mg/l alumina nanoparticles as an additive. The performance, emission, and combustion characteristics of B20 biodiesel blend and alumina added B20 biodiesel are investigated by comparing them with neat diesel. The experimental test results reveal that the combustion and performance characteristics improved with B20 biodiesel blend with and without nanoparticles. Considerable reductions in carbon monoxide, unburned hydrocarbon and increase in nitrogen oxide emissions are attained while using B20 biodiesel blend compared with neat diesel. However, there is a significant reduction in CO, UBHC and NOx emissions for B20 biodiesel blend with nanoparticles as an additives compared with B20 biodiesel blend and neat diesel.
