Geely Binyue stainless steel silver front muffler is used for engine exhaust noise reduction

Description:

Applications:

The main function of Geely Binyue muffler is to reduce the noise generated when the car engine is working.

The principle of a car muffler is to achieve noise reduction through its special internal structure. Geely Binyue's front muffler may consist of two tubes of different lengths, which are separated first and then rendezed. Since the length difference between the two tubes is equal to half of the wavelength of the sound emitted by the car, when the exhaust gas passes through, the two rows of sound waves will interfere with each other and cancel each other when superimposed, thus reducing the sound intensity and reducing the sound transmission to achieve the effect of silence.

At the same time, the front muffler, as part of the exhaust pipe, needs to ensure smooth exhaust, low resistance, and sufficient strength. It needs to withstand higher-temperature exhaust to ensure that it will not be damaged or lose its sound-muffing effect within the specified driving range of the car.

Specifically, mufflers play an important role in reducing intake and exhaust noise. They mainly have two design parameters: transmission loss (TL) and insertion loss (IL). TL refers to the difference in the sound power of the reflected wave entering and leaving the muffler when the muffler terminal is muffler; IL refers to the difference in sound pressure level at a certain point outside the system before and after the muffler is installed.

General mufflers are divided into two different categories: dissipative mufflers and reflective mufflers. Geely Binyue's front muffler may belong to one of them or have both characteristics. The dissipative muffler is usually composed of a pipe and a chamber of lined sound-absorbing material, so that the noise is constantly absorbed and attenuated in the process of propagation, which can effectively reduce medium and high-frequency noise, and the pressure drop of the system is relatively low, but it has a poor effect on sound waves with long wavelengths. The reflective muffler is generally composed of a number of chambers of different volumes and shapes connected by pipes. By constantly reflecting and attenuating the sound waves, it is resistant to high temperature and corrosion, and can work in the impact airflow environment. The price is low and the maintenance cost is low, but in some frequency ranges, the exhaust sound pressure is almost almost attenuated.

In a word, while reducing noise, the Geely Bin Yueqian muffler ensures the normal operation of the exhaust system and the performance of the engine, providing a more comfortable driving environment for the driver.
