6 CTA 8.3 G1-1 Cummins engine performance & exhaust emission tests using methyl ester Mahua oil and diesel fuel blends

Abstract

A Cummins 6 CTA 8.3G1-1 turbocharged DI diesel engine was fueled with blends of esters of Mahua oil and the performance and emissions were compared with diesel. The neat biodiesel, 10%, 20%, 40%, 60%, 80%, and base fuel were tested at constant load (28% of rated load) and at constant speed of 1500 rpm. This experiment is conducted on D.G Set, used to supply power to mining equipments in MSPL Iron Ore Company Hospet. Dist. Bellary. The objective of this study was to evaluate the impact of various blends of biodiesel on engine performance and emissions. Neat Mahua oil poses some problems when subjected to prolonged usage in CI engine. These problems can be reduced to minimum by subjecting the Mahua oil to the process of transesterification. Various properties of the biodiesel thus developed are evaluated and compared in relation to that of conventional diesel oil. Copyright Enviromedia.
