Comparative evaluation of performance and emission characteristics of a diesel engine fuelled with diesel and biodiesel blend at different load

With increasing population and rapid industrialization prompted the scientific community to find alternate source of fuel that must be convertible, locally available and environmental friendly. In this context, the role of biodiesel may be found significant in terms of commercially and technically viable. Present study was carried out to evaluate performance and emission characteristics on a 5.2 kW single cylinder water cooled engine using diesel and biodiesel blend at different engine load (0, 20%, 40%, 60%, 80% and 100%). The results revealed that the emission of CO reduced by 10.34% with biodiesel blend in comparison to diesel, while NOx emission in case of biodiesel blend was found to be higher than diesel. The brake thermal efficiency and mechanical efficiency was found to be lower than diesel by 3.6% and 5% respectively.
