Exhaust System: How Does A Muffler Work?

Your automobile exhaust system is all about pollution (both in sound and the emission of harmful gases). An exhaust system has two basic components; the muffler and catalytic converter.

Mufflers:

If you've ever heard a car engine running without a muffler, you know what a huge difference a muffler can make at dampening your engines exhaust noises. Most cars have basic mufflers that deaden sound and produce a common low-level noise.

Located inside the muffler is a set of tubes. 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.

A chamber called a resonator is connected to the first chamber. The resonator contains a specific volume of air and has a specific length that is calculated to produce a wave that cancels out a certain frequency of sound.
Catalytic Converters:

A very vital component in the exhaust system of a car is the catalytic converter. Its job is to convert harmful pollutants into less harmful emissions before they ever leave the car's exhaust system. Catalytic converters are amazingly simple devices, so it is incredible to see how big an impact they have.

Most modern cars are equipped with a three-way catalytic converter, referring to the three regulated emissions it helps to reduce. The catalytic converter forces the exhaust fumes through different chambers composed of different metal filters which absorb the toxicants, doing a great job at reducing pollution. Automobile designers are continually focused on creating a catalytic converter that will be even more efficient at reducing pollution and emissions control.
