What is Catalytic Converter? | How Catalytic Converter Works? | Hindi

Catalytic converter is a device that converts the toxic gases from vehicle's exhaust to the less toxic ones. The catalytic converters catalyse the reactions which convert the poisonous gases in vehicle's exhaust to some other gases which are non poisonous in nature. This device has platinum, palladium and Rhodium based ceramic blocks. These blocks are porous and has honeycomb structure. These metals are extremely precious and hence the use of them makes the Catalytic Converters very costly components. Catalytic Converters are fitted in vehicle exhaust system between exhaust manifold and the muffler. The gases coming out of the exhaust manifold pass throughout them and their harmful contents are reduced significantly. There are two types of catalytic converters : 1. Two way catalytic converters 2. Three way catalytic converters Two way catalytic converters The two way catalytic converters act on two harmful gases 1. Carbon monoxide CO 2. Hydrocarbons HCs They have only one ceramic block i.e. oxidising block. This block consists Platinum and Palladium based ceramics and has honey comb type structure. The exhaust gases when passes through this porous block, the following oxidising reactions take place 1) For Carbon monoxide CO + O2 -- Co2 2) For Hydrocarbons HC + O2 -- H2O + Co2 Both the gases CO and HC get oxidised to CO2 and (CO2 + H2O) respectively. CO2 is a non toxic gas, although it causes global warming but it is also very essential for plants. Hence in this way the poisonous gases like Carbon monoxide and Hydrocarbons get converted to a non poisonous gas Carbon dioxide. Three Way Catalytic Converters The two way catalytic converters were serving the purpose excellently, but a need was felt for a device which can reduce the level of Nitrous Oxide in exhaust gases. The three way catalytic converters were introduced to solve th purpose. Three term three way means it acts on three gases i.e. 1) Carbon Monoxide 2) Hydrocarbons 3) Nitrogen oxide The three way catalytic converters have an additional reducing ceramic block fitted just before the oxidising block in its assembly. This additional reducing block is made of Platinum and Rhodium based ceramic materials. While the Oxidising block is again made of Platinum and Palladium based ceramics. The reducing block acts on NOx and reduces it to Nitrogen (N2) which is again a non toxic gas. The Oxidising block has the same function as it had in two way catalytic converters. It oxidises the Carbon Monoxide and Hydrocarbons to Carbon dioxide and water. The reactions taking place in this device are: At reducing block NOx -- N2 + O2 At oxidising block CO + O2 -- Co2 HC + O2 -- H2O + Co2 In this way three way catalytic converters reduces the level of CO, HC and Nox in exhaust gases by converting them to other non toxic gases. #CatalyticConverter #CatalyticConverterWorking #Hindi The wait is finally over.
