Abstract The use of biodiesel is rapidly expanding around the world making it imperative to fully understand the impacts of biodiesel on the diesel engine combustion process and pollutant formation. Biodiesel derived from non-edible feed stocks such as mahua MadhucaIndica are reported to be one of the feasible choices for developing countries including India. But one discomforting aspect is its emissions coming out of it. Emission control is one of the biggest challenges in todays automotive industry. Emission control can be achieved either by controlling combustion or by treating the exhaust gas. The latter is comparatively easier since there is less or no need to modify the engine. One such after treatment method is the use of catalytic converter. This paper is more concerned with an experimental investigation to study the diesel engine emission characteristics using Mahua biodiesel mahua oil methyl ester with the help of a Three Way Catalytic converter TWC with DEF Diesel Exhaust Fluid by running the engine in steady state conditions. The various exhaust parameters such as CO HC and NOX emissions were recorded and were found out to be comparatively very less when TWC converter was connected at the end of the exhaust tail pipe. Almost 90 NOX emissions got reduced and the emission values recorded were much less when compared to Bharat stage- IV Norms for selected engine at all operated loads with retrofit arranged.
