A muffler (or silencer in British English) is a device for reducing the amount of noise emitted by a machine. On internal combustion engines, the engine exhaust blows out through the muffler. The internal combustion engine muffler or silencer was developed in parallel with the firearm suppressor by Hiram Percy Maxim.

Dual exhaust pipes attached to a car's muffler

Mufflers are typically installed along the exhaust pipe as part of the exhaust system of an internal combustion engine (of a vehicle, or stationary) to reduce its exhaust noise. The muffler accomplishes this with a resonating chamber, which is specifically tuned to cause destructive interference, where opposite sound waves cancel each other out.

Advantages

Mufflers that reduced backpressure relative to earlier models became increasingly available in the late 20th century, and resulted in increased engine efficiency, performance, power output, and simultaneously decreased overall wear and tear on the engines' components, as well as sound to levels in compliance with the law.


Types and positions of mufflers

  • With cars, lengthwise underneath, blowing backwards at the rear.
  • With large diesel-powered trucks:-
    • Mounted vertically behind the cab
    • Crosswise under the front of the cab, blowing sideways.
  • With motorcycles:
    • Usually, beside the engine and rear wheel blowing backwards.
    • Sometimes nowadays, under the seat blowing backwards from under the back of the seat.

Motorcycle enthusiasts sometimes use the term "raygun" for the old shape of motorcycle exhaust silencer/muffler with a long straight cylindrical barrel that merged roundedly at each end into the pipe, as in this image and this image.

Swiss style muffler (1688 words)
A muffler works by providing a large chamber in which the sound of combustion and turbulence are reduced.
In some mufflers, the exhaust gases are forced to change direction drastically in their pell-mell trip to the free atmosphere.
Mufflers are most effective when they are located as close to the exhaust outlet of the cylinder as it is practical to place them.
