Description

technical field

[0001] The invention relates to the technical field of mufflers, in particular to a muffler for an internal combustion engine. Background technique

[0002] The so-called muffler, a muffler is a device that allows airflow to pass through, but can prevent or reduce sound transmission. It is an important measure to eliminate aerodynamic noise. The muffler can block the transmission of sound waves and allow airflow to pass through. It is an effective tool for noise control , with the development of science and technology, the scope of application of muffler technology is becoming wider and wider, which involves a muffler for internal combustion engines. The internal combustion engine will generate exhaust gas during operation. If the exhaust gas is discharged directly, it will produce a lot of noise and affect Therefore, the user usually needs to install a muffler. Because the temperature of the exhaust gas generated by the internal combustion engine is relative...
