For the past few decades, many luxury vehicle brands have appeared in the North American market, and BMW may be considered one of them. While BMW is just one of the many auto manufacturers in this vehicle market category, the company proves that their vehicles have something more than what the other luxury vehicles have. Aside from luxury, BMW vehicles showcase outstanding performance, a quality that can rarely be matched by its competitors. At the heart of every BMW vehicle are large and powerful V6, V8, or V12 engines that gives it an unreachable level of performance.

But as the engines used on BMW vehicles gets larger and more powerful, they tend to pose more harm to the environment. Gasoline-powered internal combustion engines, the same kind of engine that BMW vehicles are equipped with, are known to emit a lot of harmful gaseous substances as byproducts of their fuel combustion process. The larger the engines used in a particular vehicle, the larger is the amount of harmful substances that its exhausts carries. It is therefore important for every BMW vehicle to be equipped with a high performance BMW catalytic converter that can control its engine's emission levels.

Catalytic converters are emission-control products designed to convert harmful substances like carbon monoxide, nitrogen oxides and hydrocarbons, all of which are byproducts of an imperfect combustion process, into less harmful substances before they are emitted outside the vehicle's exhaust system. A typical catalytic converter is composed of two types of catalysts to perform this function. A reduction catalyst in the catalytic converter converts nitrogen oxide into nitrogen and oxygen, while an oxidation catalyst performs a second combustion to convert the carbon monoxide and other hydrocarbons to carbon dioxide and water.

Now, all these harmful substances should not have existed if the combustion process was perfect. Sadly, current engine technologies cannot perform a perfect combustion process. But most modern catalytic converters carries with it an integrated control system that can measure the amount of oxygen injected in the engine. This system can then transmit its data to the engine computer, which in turn can adjust the air-to-fuel ratio for the engine to achieve a near perfect combustion process.

While catalytic converters are apparently small, it performs a big function in protecting the environment from harmful vehicle emissions. So if your BMW catalytic converter is already damaged or worn out, you better replace it with a new one right away.
