An exhaust system is a vehicle’s discharge control device that uses catalyzed compound reactions to convert the deadly byproducts of burning within an ignition motor’s fumes into less toxic chemicals. This study is to analyze the catalytic converter for Euro 7 emission norms which is been carried out by using aluminum oxide and chromium oxide for the reduction of emissions and to find out the effect on emissions emitted by the catalytic converter has been analyzed. The experimental setup consists of the test engine, catalytic converter, AVL exhaust fuel analyzer and various measuring instruments. A single cylinder four stroke diesel engine has been used as the test engine. Initially, the engine was running with the existing catalytic converter with no other addition and the emissions have been analyzed using gas analyzer of AVL. The exhaust emissions and the design of the catalytic converter were considered as a main challenge where it was observed that HC decreased with 29%, NOx with 30%, CO2 with 24%, increase in O2 with 10%, Lambda increases with 12%. The major constituents which contribute to the emissions are carbon monoxide (CO), Oxides of Nitrogen (NOx), Hydrocarbons (HC), Carbon dioxide (CO2), and Oxygen (O2) which comes out from the exhaust port of the catalytic converter. This research has established the platform for the further going work which can be done for achieving the Euro 7 emission norms by working in the similar way on the newly developed catalytic converter which can be seen shortly in the upcoming vehicles with the better quality of design and structure of the catalytic converter.
