Tone Down the Noise With the Mercedes Benz Muffler

Mercedes Benz cars are known for their technological innovations and their emphasis on safety. They were first to introduce the safety cage, anti-lock brakes, airbags, traction control and many other safety features that are standard in every car they produce. Mercedes or Benz has also become one of the world's top status symbols for the rich and famous. If you want the “look," the “luxury” or simply the “name,” Mercedes is the right brand of car for you.

Wouldn't it be a drag if you're driving around on your Benz and you hear a deafening kind of noise coming from within? I'm pretty sure it would reduce the whole “Benz experience.” This is pretty much the main reason why mufflers were invented.

The muffler is also known as “silencer” in other parts of the globe. It actually came from the term “muffle” which means to wrap with something to deaden or prevent sound.

A muffler is typically installed along the exhaust pipe as part of the exhaust system of the engine. It's connected between the tail pipe and the catalytic converter. Its main purpose is to reduce the tremendous amount of noise that an engine produces.

When the exhaust gases from an internal-combustion engine are released directly into the atmosphere, they create a loud noise, caused by the passage of the exhaust gases from the high pressure of the cylinder to the normal pressure of the atmosphere. To be more specific, when an exhaust valve opens, it discharges the burned gases at high pressures into the exhaust pipe, which is at low pressure. This type of action creates sound waves or what we call “noise” that travel through the flowing gas, moving much faster than the gas itself. Typically a muffler consists of a tubular metal jacket containing perforated pipes and chambers through which the exhaust gases flow before entering the atmosphere.

But what really happens in the inside? A Mercedes muffler consists of several tubes with holes in it. These tubes are designed to create reflected waves that interfere with each other or cancel each other out. The exhaust gases and the sound waves enter through the center tube. They bounce off the back wall of the muffler and are reflected through a hole into the main body of the muffler. They pass through a set of holes into another chamber, where they turn and go out the last pipe and leave the muffler. This time, the noise would have been reduced.

There are two types of muffler designs. One type uses several baffled chambers to reduce noise. The other type sends the gases straight through perforated pipe wrapped in metal or fiberglass and is designed to reduce back pressure and, consequently, makes slightly more noise because they produce much less restriction.

An example of this second type is the glass pack or a cherry bomb. This specifically uses absorption to reduce the sound.

Mufflers of this type were invented in the late 20th century. Some of its advantages were increased engine efficiency, performance, power output, and simultaneously decreased overall wear and tear on the components of the engine.
