A Review on the Performance, Emission and Combustion Characteristics of Karanja, Jatropha and Polanga Biodiesel and its Blends in a Diesel Engine

Abstract

Energy is an essential factor for improving the quality of life, human welfare, socio-economic growth, and development. As the world's energy demand increases , the need for energy security as a result of rapid depletion of fossil fuels has been an issue of concern.Hence, an alternative source of energy needs to be established. Biodiesel, which is biodegradable, renewable, non-toxic, and has similar properties to conventional diesel fuel could serve as an alternative source of fuel. When compared to mineral diesel, biodiesel has lower CO, CO₂, HC, and smoke opacity emissions.In terms of brake thermal efficiency (BTE), brake specific energy consumption (BSEC), smoke opacity, and exhaust emissions, biodiesel-fueled engines performed slightly better than diesel-fueled engines. This paper reviews the performance, emission, and combustion characteristics of some non-edible oils of karanja, polanga, and jatropha-based biodiesel obtained from experiments performed at different conditions.
