What do mufflers do

The muffler filters these fumes into the atmosphere. If there is a crack or hole in the muffler, the fumes can make their way to the interior of the vehicle. Exhaust fumes contain carbon monoxide and other highly hazardous chemicals and toxins. Over time, this can cause serious harm to you and your passengers.

Like any component of your vehicle, mufflers can deteriorate over time — both internally and externally. How quickly this happens depends entirely on the age and use of the vehicle as well as where you live. The most common reason for mufflers to break or develop holes is external rust. Rust forms on the outside of the muffler and eats through its structure. This can be caused by exposure to substances such as salt, which is often used on roads in the winter time. Rust can also form inside of the muffler due to condensation.

What Does a Muffler Do? Explanation of the Function, Maintenance, and Repair. Why Mufflers Need to Be Replaced The internal and external components that make up the muffler can deteriorate over time. External Rust The most common reason for a muffler to fail is rust. Internal Rust Rust can also form internally due to condensation from normal day-to-day use. Decrease in Fuel Efficiency You may notice that your car is running hotter than normal, or see a decrease in fuel efficiency.

Engines need to generate a ton of power, and, as a result, they create numerous pulsating sounds that reverberate through the exhaust valves. Thousands of these pulses are created every single minute. Without a properly working muffler, your vehicle is going to be incredibly noisy. In fact, excessive noise is a good way to tell if you require a new muffler.

The question then arises: How do mufflers cancel out this noise? If you were to open up a muffler, you would find a series of tubes, baffles, and chambers. These components work to reflect sound waves created by the engine. They are reflected in such a way that the waves actually cancel each other out. So, how does it break down the loud noises into mild bearable sound? The answer is—simple physics. Combustion engines need to get rid of burnt fumes in order to take in fresh air and fuel.

There is a whole mechanism that has been created just to get rid of these burnt fumes so that they can escape the car in the quietest way possible. The fumes exit the engine through exhaust manifolds, which is a set of pipes attached to each cylinder to collect the fumes.

The manifolds are combined into one single exhaust pipe or two in some cars with bigger engines. The fumes run to the back of the car and enter the muffler before the final exit. The muffler is built with a set of tubes inside it.

These tubes are designed in such a way that they reflect the sound waves back and forth. The noise of the engine is significantly reduced through this reflection process.
