What happens when a car's exhaust pipe is blocked?
2 Answers
When a car's engine exhaust system becomes blocked, corresponding fault symptoms will appear depending on the severity of the blockage. Here is an introduction to car exhaust pipe knowledge: 1. Definition: The car exhaust bellows, also known as the car exhaust flexible hose, is installed in the exhaust pipe between the engine exhaust manifold and the muffler. It creates a flexible connection for the entire exhaust system, serving to reduce vibration and noise, facilitate installation, and extend the lifespan of the exhaust muffler system. 2. Material selection: Ferritic stainless steel has a small thermal expansion coefficient and high thermal conductivity. It exhibits good high-temperature oxidation resistance under repeated heating and cooling conditions, along with excellent pitting corrosion resistance.
I've been driving for twenty to thirty years and have seen many cases of exhaust pipe blockages. Once it's clogged, the engine is like a person being strangled, unable to breathe. You'll notice the car accelerates sluggishly, the throttle doesn't respond when pressed, and the engine sounds strange—either humming or popping. In severe cases, it might even stall on the road. What's more dangerous is that exhaust fumes can't escape, causing carbon monoxide to backflow into the car, leading to dizziness while driving and increasing the risk of accidents. Once, my exhaust got blocked because mud clogged the pipe opening, but luckily I pulled over in time. I recommend checking the bottom of the exhaust pipe before driving, clearing out carbon deposits or debris, and maintaining the exhaust system regularly. Safe driving is the top priority.
