What does the muffler do?

I am a student and I want to work on my own car when I get older. I am confused about the muffler. What does the muffler do?

What does the muffler do? It muffles noise!
The first function of the muffler is muffling noise, or reducing the volume of the
engine noise
. That’s how this part got its name.
Whenever the exhaust valve opens, burnt gases are released. These gases create super powerful sound waves. To protect your ears—and the ears of other drivers—from these loud sounds, the muffler uses a series of metal tubes to deflect the sound waves from the engine.
The second function is to direct exhaust fumes away from the vehicle. Carbon monoxide and other output can be dangerous to breathe, so the muffler sends them away from the car.
If you’re studying cars, you might want to start learning about
car insurance
. If you’ll be driving soon, you can ask your grownups to use the

 app to find the cheapest policy to add you to their plan.
