How long will it take for problems to occur if a steel wool pad is placed in the exhaust pipe?

[LeMichael]

If a steel wool pad is stuck in the exhaust pipe and cannot be removed, the area through which air can pass will begin to decrease within a few days, leading to an increase in exhaust backpressure. Excessive exhaust backpressure can cause poor engine exhaust flow, preventing the complete expulsion of exhaust gases and reducing the intake of fresh air. This results in decreased charging efficiency of the vehicle, leading to a reduction in the engine's output power and torque, which can cause sluggish acceleration and even engine vibration. Below is a detailed introduction to this issue: 1. Introduction One: The exhaust pipe is a device designed to reduce vibration and noise, facilitate installation, and extend the lifespan of the exhaust muffler system. It is installed between the engine exhaust manifold and the muffler, providing a flexible connection for the entire exhaust system. 2. Introduction Two: Some vehicles are equipped with turbochargers at the exhaust pipe location to increase horsepower. To minimize exhaust resistance, the exhaust pipe outlet is typically positioned at the lower part or the rear of the vehicle.
