[Free Data Download & Acoustic Analysis] Muffler Noise Reduction Design

Analysis of acoustic transmission loss and radiated sound

The muffler, represented by the automotive exhaust silencer, refers to a silencer (or silencer) installed in a part of the duct that serves as a passage for sound and fluid. The sources of noise from this muffler can vary, but it often seems to be related to the explosion sounds from the engine and the relatively low-frequency sounds that accompany it. To accommodate these low frequencies, the design incorporates acoustic elements such as expansion type, resonator type, branch pipes, and expansion resonance type that can resonate at low-frequency ranges, along with interference type, absorption type, and resistance type acoustic elements that are effective over a wide frequency range or in the mid to high frequency range. - The importance of coupled analysis considering acoustic transmission loss and sound propagation to external areas - For the design of automotive mufflers with high sound attenuation performance If you are interested in acoustic design, please take a moment to read this.

Environmental Device: Black Smoke Removal Muffler

Used in combination with a catalytic muffler. Black smoke removal muffler.

If too many carbon particles adhere to the demister, it may cause clogging, leading to an abnormal increase in back pressure, which could result in engine overheating or damage to the wire demister. Please pay close attention to maintenance management. 【Maintenance Management】 - Regularly (every 5 to 10 days of operation) remove the cleaning plug, and while the filter is installed, run the engine at idle to discharge the accumulated carbon into a collection bag or similar. - It is also acceptable to use a vacuum cleaner for cleaning. The demister should be inspected at the start of each work session; pull out the demister and either shake off the carbon or soak it in a neutral detergent solution to clean off the adhering carbon. - Inspect the main body, inlet pipe, outlet pipe, and brackets for cracks. - Be careful not to inhale carbon particles during work. ● For more details, please contact us.
