Volvo Muffler Mellows Down Emission Noise

By: Evander Klum

When stepping on the gas pedal, one may hear a rumbling noise coming out of the tailpipe. That would be the emission being released to the atmosphere. While the noise can sometimes pose a problem for some, others have a solution for it. For Volvo owners, this comes in the form of quality Volvo mufflers.

A Volvo muffler is a device used for reducing the amount of noise emitted by a vehicle. It is usually installed along the exhaust pipe as part of the exhaust system of the engine. Inside the Volvo muffler is a set of tubes 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, wherein 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 of the last pipe, leaving the muffler. Volvo mufflers have a chamber dubbed as a resonator which is linked to the first chamber by a hole. This resonator has a specific volume of air and a specific length that generates a wave canceling out a particular sound frequency. It is an ordinary equipment piece found on vehicles, hanging under the car rear. However, big mufflers on diesel-powered trucks are fixed vertically behind the cab.

One characteristic of a is the amount of backpressure it produces. In the late 20th century, mufflers that decrease backpressure came out in the industry. In effect, there was an enhancement in engine efficiency, performance, and power output. At the same time, there was a reduction in the overall wear and tear on the engines' components.

Glass pack or cherry bomb type of mufflers can lessen backpressure. They use mere absorption to diminish the sound. The exhaust flows directly through a pipe punctured with holes that is surrounded by a layer of glass insulation. The pressure pulses are absorbed by the insulation.
