What Happens When a Steel Wool Ball is Inserted into a Car's Exhaust Pipe?

[VictoriaLynn]

The effect of inserting a steel wool ball into a car's exhaust pipe is an increase in cylinder pressure, which can prevent the engine from starting and reduce the engine's lifespan. The functions of a car's exhaust pipe are: 1. To expel the exhaust gases produced after engine combustion. 2. To reduce vibration and noise, thereby extending the life of the exhaust muffler system. Maintenance methods for a car's exhaust pipe include: 1. Avoiding water ingress into the muffler during rainy weather or car washing. 2. Regularly cleaning the dirt inside the exhaust pipe and applying rust-proof oil. Reasons for a car's exhaust pipe making a popping sound: 1. Excessively high concentration of the air-fuel mixture, where unburned mixture enters the exhaust pipe and encounters fresh air, causing backfire. 2. Poor valve sealing leading to incomplete combustion.
