Purpose of Exhaust Systems
Exhaust systems perform several functions, including deadening noise made by the engine and controlling the emissions from your vehicle. The exhaust system includes the muffler, exhaust manifold, oxygen sensor, catalytic converter and exhaust pipe.
Deadening Sound
The muffler is the main component of the exhaust system that deadens sound. Mufflers use sound baffles, which absorb the loud sound of the engine. Some mufflers use fiberglass to absorb sound.
Controlling Emissions
The catalytic converter uses heat and metals to convert harmful fumes, like carbon monoxide, into less harmful ones, like water vapor. Other harmful fumes that the exhaust eliminates or reduces are carbon dioxide, sulfur dioxide, phosphorus and lead.
Significance
Reducing passenger car emissions is particularly important for environmental protection. According to Hybrid Vehicles, cars emit millions of tons of pollutants every day. Pollution control has improved dramatically over the past 20 years with advances in converters and the introduction of hybrid vehicles.
Good Post! Many people are still ignorant about what these exhaust pipes actually are for. We have had many customers that come to ask us about what role exhaust pipes really play, are they important, where to find the best ones etc. We would like to encourage more blogs of this kind so that awareness about automobiles could spread.
