What Are the Symptoms of a Damaged Car Exhaust Muffler?

[SanBrooklyn]

The symptoms of a damaged car exhaust muffler include increased engine noise. The working principle of the exhaust muffler is as follows: the car exhaust pipe consists of two pipes of different lengths, which first separate and then converge. The difference in length between these two pipes equals half the wavelength of the sound waves emitted by the car, causing the two sets of sound waves to interfere with each other when superimposed, thereby reducing the sound intensity. The maintenance methods for the exhaust pipe are: 1. Waterproofing: When driving in the rain or going to a car wash, be careful to prevent water from entering the muffler, which can cause rust and affect the exhaust pipe's performance; 2. Rust prevention: Remove the muffler, block the drain hole, add rust-proof oil, and ensure it spreads evenly inside the cylinder before reinstalling the muffler; 3. Cleaning: The exhaust pipe is often exposed to the outside, similar to the car's interior, and accumulated dirt inside can affect normal operation, so it's important to keep the exhaust pipe clean.
