Abstract: Catalytic converter is basically a device which is used to convert toxic harmful gases into less harmful gases from the exhaust of a automobile. Without this device, toxic gases which are emitted from the exhaust of an automobile can’t be converted to less toxic gases. An existing and catalytic converter which is present currently in the market uses catalyst of Platinum group such as Palladium, Platinum and Rhodium which are highly expensive catalyst. Therefore, to improve the durability and to reduce the cost of the catalytic converter, we are replacing the coating of catalyst by Aluminium Oxide and Silicon Dioxide which have high thermal stability, durability and are available are cheaper rates. This project focuses on the methodology involved in the fabrication of new catalytic converter and analysing the emission rates of toxic gases like Nitrogen Oxides, Carbon Monoxide and hydrocarbons. The Silicon Dioxide coated converter reduces the NOx and CO emission and the Aluminium Oxide coated converter reduces the CO and HC emission. The nitrogen oxide gases have been reduced 20.38% at maximum load and 55.2% at minimum load using Silicon dioxide coated convertor. The hydrocarbon emission has been reduced up to 88.8% at maximum load and 80% at minimum load. CO emissions were reduced by 75% and 80% at maximum and minimum loads in both the converters.
