Catalytic Converter




Your car's exhaust system may be the most unnoticed and neglected part of your vehicle. However, seeing its brighter side it is in without doubt a very important car part. Without it you car cannot go to places. What is a car exhaust? For some car owners, it is just a pipe that leads the product of gasoline conversion out into the atmosphere. Technically, it can be described well than just a mere pipe. A car exhaust system is a tubing that is used to guide the reaction of exhaust gases such as carbon monoxide away from a well controlled combustion in your car's engine.

The importance of this system prompts every car owner like you to regularly check its functionality and effectively. Along with today's increasing pollution level, it is vital to take care and check regularly your cars catalyctic converter. What is a catalyctic converter? It is a very important part of every modern exhaust system. It essentially converts harmful gases produced by your car into harmless ones. Although every car in this world is a source of pollution, a catalyctic converter helps minimize this.




In 1975, the very first catalyctic converter was made. How does this interesting device work? Catalytic converters are surprisingly simple devices. This is why it is amazing to see how great an impact they have to the world. The main purpose of this device is to reduce pollution. It works by undergoing a quick chemical reaction. There are two different types of catalyst at work in the catalytic converter. This comprises of a reduction catalyst and an oxidation catalyst. Both of these types consist of a ceramic structure enclosed with a metal catalyst. This is usually rhodium, platinum, or palladium. The idea of this environment-friendly converter is to make a structure that interprets the maximum surface area of catalyst to the exhaust flow. On the other hand, it also minimizes the amount of catalyst needed, as the materials are highly expensive. Some of the latest converters have even begun to use gold along with the more traditional catalysts. This is because gold is cheaper than the other materials. It could also increase oxidation, which is the chemical reaction that lessens pollution by up to forty percent.

How does the catalyctic converter control pollution and improve the performance of your car? This is possible through the third stage of catalyst conversion, which is the control system. This stage monitors the exhaust flow and uses this to control the fuel injection system. An oxygen sensor then controls the amount of oxygen to be released in the exhaust. The catalytic converter does an excellent job at decreasing pollution. However, it can still be substantially improved. One of its greatest limitations is that it only works at a moderately high temperature. When you begin your car cold, the converter can do nothing to lessen the pollution in your exhaust. Moving your catalytic converter closer to the engine can solve this problem.

When buying a car exhaust system it is in fact very important to know its specification.
