The present work deals with a development of a urea Selective Catalytic Reduction (SCR) system for the reduction of harmful nitrogen oxides (NOx) emission in a commercial single cylinder, Direct Injection (DI) diesel engine. In the investigation, to predict the emission and the sizing of catalytic converters are chosen under particular operating condition to convert nitrogen oxides emitted from the engine into harmless Nitrogen (N2) and water (H2O). In order to reduce the cost of the SCR systems, non-noble metal oxides such as zeolite, zinc oxide and magnesium silicate are chosen as catalysts. Here kaolin is used as a binder for zeolite while sodium hydroxide is used as a binder for other two catalysts. In summing up, among all catalysts considered in the work, zeolite based catalysts are more effective in the conversion of NOx (85.28%) to meet the present emission standards
