How Deep to Insert a Steel Wool Ball into the Exhaust Pipe

Backpressure reaches around 35kp, calculated based on a 10cm exhaust pipe opening. Additional information is as follows: 1. The functions of a car's exhaust pipe can be broadly categorized into three: 1. Noise reduction: A good exhaust pipe can make the sound feel softer and quieter. 2. Reducing environmental pollution: The exhaust pipe contains a three-way catalytic converter that filters the emitted gases, minimizing environmental pollution and respiratory hazards to humans. 3. Experiencing the feeling of driving a sports car: Some people want to experience the sensation of driving a sports car, which cannot be achieved without an exhaust pipe. 2. The effects of blocking the exhaust outlet are as follows: 1. Automatic transmission cars will downshift: When the exhaust pipe is blocked, automatic transmission cars will experience a decrease in engine power and may downshift, which is due to the blocked exhaust pipe. 2. Reduced acceleration power: The inability to expel exhaust gases leads to incomplete combustion, resulting in symptoms like sluggish acceleration when the exhaust flow is obstructed. 3. Abnormal noises: Unusual sounds from the exhaust often accompany excessive emissions, and prolonged neglect can potentially damage other components of the car. 4. Backfire phenomenon: Some exhaust gases remain trapped in the cylinders, and when the intake valve opens, the air-fuel mixture is still burning. Consequently, the burning mixture can backflow through the open intake valve into the intake manifold.
