What is the Box Connected to the Exhaust Pipe?

[DiGenevieve]

The box connected to the exhaust pipe is the exhaust muffler. Function: For the car body, the exhaust pipe serves to reduce vibration and noise, as well as extend the lifespan of the exhaust muffler system. The main material of the exhaust pipe is stainless steel. For most vehicles, since the exhaust gas exits the engine under high pressure, the noise it produces can be extremely irritating. The primary role of the exhaust pipe is to mitigate this noise by incorporating a muffler inside, significantly reducing the vehicle's noise levels. Working Principle: It operates by diverting the airflow through multiple channels, where the streams interact, causing friction and collisions that gradually reduce the airflow's velocity. This process repeats cyclically, ultimately allowing the exhaust gas to flow out through the car's exhaust pipe with reduced noise, achieving the effect of daily noise reduction in vehicles.
