The catalytic converter plays a crucial role in your car's exhaust system; it filters harmful pollutants from the engine exhaust into more environmentally-friendly compounds. It is located underneath your car connected to the exhaust system. Its primary function is to convert the three harmful compounds; carbon monoxide, unburnt fuel and nitrogen oxide into carbon dioxide, water, and nitrogen. The hot gases from the engine pass through the?exhaust pipes?into the catalytic converter. The toxic by-products from the fuel are removed by oxidation and reduction reactions that take place inside the catalytic converter.

Basically, the catalytic converter takes harmful emissions and makes them substantially less harmful. With today's environmentally-friendly legislation in place, most states (32 out of 50) require a regular emission test for each car. The reason for most failed tests is directly related to catalytic converter problems. That's why replacement catalytic converters are so important - if your car doesn't pass the emission test, you can't drive until it's fixed!

Most modern cars are equipped with three-way catalytic converters which have three regulated emissions. The reduction reaction takes place at the first stage followed by oxidation in the second stage. The control system monitors the exhaust stream and uses the information to control the fuel injection system in the third stage. If you find that your exhaust system is leaking or if your car does not pass emissions, you need to check the performance of your car's catalytic converter and get it replaced if it is faulty. sells a wide range of catalytic converters at reasonable prices.
