Car mufflers are mainly used to reduce the noise generated by car engines during operation, and they are usually fixed by straps, hanging ears, or flexible gaskets. Due to the harsh working environment of mufflers, high temperatures, carbon deposits, and steam corrosion can easily lead to malfunctions. Therefore, daily maintenance by muffler manufacturers is particularly important.
To determine whether the muffler intake pipe flange is leaking, you can check whether there are black smoke marks on the flange end, or pay attention to whether there is a crackling sound on the flange end when the engine is not turned off. If there is, the sealing gasket should be replaced. After starting the engine, due to the high temperature of the exhaust pipe itself, do not let your body touch the exhaust pipe to avoid burns.
Determine if the muffler is damaged: When the engine is running, if there is abnormal advertising noise in the exhaust, it is generally due to corrosion of the muffler's internal partition; If a horn sound is emitted, the muffler shell is generally corroded and has corrosion holes; If sexual noise is emitted, it is usually due to blockage in the muffler channel.
Master's summary: In reality, many car owners never clean the carbon deposits inside the exhaust pipes and mufflers, resulting in excessive internal carbon deposits, reduced exhaust area, inability to discharge exhaust gas, insufficient fresh air pressure, and further deterioration of engine combustion conditions.
