The modern internal
combustion engine is a wonder of science and engineering. By compressing and
igniting petroleum in controlled bursts a few hundred times a second it is able
to propel often over a ton of steel forward safely and reliably for hundreds of
thousands of miles. Each of these controlled bursts of combustion is very much
like a tiny explosion, and sounds very much like one. Even small two-cylinder
engines can become extremely loud without the right components to dull their
roar.
As anyone who has
ever been to a motorcycle rally knows, a torrent of unsuppressed engines can be
deafeningly loud. Highways packed with much larger engines could be heard from
miles away without the right mufflers. Cities could become practically
unlivable from the pounding reverberations of unbridled diesel engines
resonating between skyscrapers. Life without mufflers could become genuinely
unpleasant.
Muted by the
Muffler:
Mufflers use a few
techniques to dampen engine noise with minimal weight and back pressure. In
their simplest form, they are just baffled steel tubes lined with dampening
material. Modern systems are harmonically tuned to create destructive
interference that cancels out engine noise. A new, more efficient muffler is
often an easy way to coax more horsepower out of a vehicle by reducing back
pressure while remaining within your state's noise regulations.
Mufflers are an
effective means of controlling engine noise by redirecting exhaust gases into
harmonically tuned chambers lined with sound deadening materials. This
inevitably creates some back pressure and more efficient mufflers may offer
better performance.
