Noise is generated in the engine when exhaust gases are evacuated. To suppress it, a device such as a silencer is used. It refers to the exhaust tract of the engine. In the automotive market, you can find a fairly large selection of muffler designs that differ in type, material and other criteria. On the Auto World website you can find out what car mufflers exist and how to choose the best option.
Features of the car muffler
Having examined and analyzed the operation of mufflers, we can note their features. During the operation of the engine, sound waves are formed, which, passing through the chambers, enter the muffler. An important task of the device is to drown out the vibrations of sounds.
What are the mufflers made of?
Various types of steel are used as the main material. Let's consider the main materials for them:
- Carbon steel is a fairly budget material for a muffler. It handles well, but does not have high performance properties. Therefore, within one or two years, it corrodes. This is due to the effects of various chemicals and high temperatures.
- Alumina-zinc steel is more resistant to corrosion than carbon steel. Therefore, its operational period is slightly increased. However, they are inexpensive in terms of price range.
- Stainless steel is the most ideal choice for a muffler. Due to the technical characteristics of stainless steel, products made from it have a long service life, wear resistance, strength and reliability. However, in terms of price, they are quite expensive.
Division of mufflers by type of construction
Depending on the type of construction, direct-flow, combined, resonant, labyrinth and others are distinguished. On sports cars, straight-flow stainless steel models are mainly used. Because of this, they have a fairly high cost. There are several chambers in the labyrinths. They perfectly dampen noise, but reduce power.
Options for selecting muffler models
If you are faced with the task of purchasing a muffler for your car, you need to pay attention to parameters such as size, appearance, type of construction, material of manufacture, build quality. For example, the dimensions should not be small. This means that the muffler contains more sound-absorbing elements.
It is also very important to pay attention to the make, model and year of manufacture of the car. So you can buy an original muffler model for a specific car brand.
