The Impact Of Government Regulations On Muffler Design In Automobiles
One of the most noticeable negative aspects of internal combustion engines is noise. With the growing number of cars on the road, governments attempted to limit this noise by insisting on muffler installation . Put most simply, a muffler is any device that reduces sound. In the context of automobiles, this sound reduction is done by catching the exhaust of the engine and routing it through a series of baffles. These baffles force the sound waves to collide and cancel each other out. While this noise reduction is necessary, it comes at a price – engine efficiency. The process of catching and forcing the exhaust through sound baffles slows it down so that the exhaust behind it builds up as back pressure. This back pressure works through the entire system and creates a bottleneck. The entire performance automobile industry has been working for years to eliminate this problem while still retaining the noise deadening effect. The first, and to date most effective, measure has been the sim
