Automobile Exhaust Treatment

Summary

Automobile exhaust treatment allows lower emissions, such as carbon monoxide and hydrocarbons, to be released in the exhaust. There are a number of ways to lower exhaust emissions. One way is to increase the performance of the engine, this allows better conversion in the fuel to carbon dioxide and water vapor. Another way is to oxidize the exhaust. The catalytic process in automobile exhaust treatment is the catalytic oxidation/reduction of pollutants in the gas exhaust. These pollutants are hydrocarbons, carbon monoxide, and nitric/nitrous oxides. Pollutants in the exhaust are formed by a partial combustion of hydrocarbons in the fuel. Pollutants in the exhaust stream are fed to the catalytic converter where they are catalyzed to form carbon dioxide, water vapor, and nitrogen gas.
