A catalytic converter is a device that uses a catalyst to convert three harmful compounds in car exhaust into harmless compounds. The three harmful compounds are: 1  Hydrocarbons (in the form of unburned gasoline).2  Carbon monoxide (formed by the combustion of gasoline).itrogen oxides lead to smog and acid rain, and hydrocarbons produce smog. In a catalytic converter, the catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb or ceramic beads that are housed in a muffler-like package attached to the exhaust pipe.
There are three types of catalytic converters: two-way converters, three-way plus air catalytic converters, and three-way converters. For the most part, each of these different converters came about because of emission regulations. Here is a summary of the catalytic converter evolution.he function of any catalytic converter is to reduce harmful emissions generated by a properly-tuned engine. Learn more here. A catalytic converter is a vital part of a vehicle emissions control system. It is designed to convert harmful engine emissions to CO2 and water.
