Automobile Catalyst are used to convert Harmful gases emitted by vehicle (CO, HC, and NOx) to less Harmful gas (CO2, H2O and N2), Catalyst Loading comprises of Platinum, Palladium and Rhodium (Rare earth metals) metal powders combined in slurry and wash-coated onto a ceramic brick. Ever since the introduction of BS6 Emissions norm (stricter emission regulation), Catalyst loading content has increased in all vehicles. The Price of these rare earth metal are increasing day by day. Typically, a BS6 regulation catalyst contains a few grams of loading content. In some vehicles there are more than one catalyst (due to regulation requirement) and in some cases catalysts are also located in the underbody, in such cases, Number and location of catalyst makes the vehicle an easy target for thieves. Recently local police authorities around the country have captured many catalysts theft gangs.
