What is the internal structure of the car muffler?

2023-02-28

The internal structure of the automobile muffler is generally composed of several parts such as an exhaust pipe, a connecting screw sleeve, a muffler cylinder and a cylinder core. The muffler is an extension of the exhaust pipe, which should ensure smooth exhaust of the engine, low resistance and sufficient strength.

The muffler is generally composed of several parts such as an exhaust pipe, a connecting screw sleeve, a muffler cylinder and a core. Automobile mufflers are used to reduce the exhaust noise of the engine, and enable high-temperature exhaust gas to be discharged safely and effectively. The muffler is an extended part of the exhaust pipe, and it should ensure smooth exhaust, low resistance and sufficient strength. Here is the relevant information:


1. Muffler: Muffler refers to the airflow pipe with sound transmission at the same time, which can be used with pipes and elbows with sound-absorbing lining or
Use noise reduction devices such as pipes with sudden changes in cross-sectional area and other pipes with discontinuous acoustic impedance to attenuate or reflect back the noise in the pipe.
The former is called a resistive muffler, the latter is called a resistant muffler, and there are also negative and anti-compound mufflers.


2. Types of mufflers: There are many types of mufflers, but their muffler mechanism can be divided into six main types, namely resistive
Mufflers, Resistant Mufflers, Impedance Composite Mufflers, Micro-Perforated Plate Mufflers, Small Orifice Mufflers and Active Mufflers.
