Exhaust Catalytic Convertor

Exhaust convertor. Cleans the unburnt exhaust gases. Does not improve fuel properties. Does not work with leaded petrol. Different catalysts for different fuels. Sulfur sensitive. Does not decarbonaize engine combustion chamber. Does not reduce engine noise and engine smoothness. Does not enhance fuel economy. Works on chemical oxidation and reduction principle. Noble metal substrates or chemicals are used. Back pressure due to exhaust configuration. Different sizes for different engine cubic capacity. Does not enhance slow speed driving range. Costlier. Fitment needs exhaust pipe cutting and welding. No power supply required unless heated catalysts are used or regeneration is required. Warm up time required for catalysts during cold starting. Does not improve fuel quality.
