What are the causes and solutions for exhaust pipe blockage?
2 Answers
Exhaust pipe blockage is generally caused by excessive carbon buildup. If the blockage is due to excessive carbon deposits, you can remove the exhaust pipe, tap the outside of the pipe with a rubber hammer to dislodge the carbon deposits inside, and then slowly pour them out from the other end of the pipe. Below are specific details about exhaust pipe blockage: 1. Poor acceleration: If during a long drive, the engine idle becomes unstable, acceleration feels weak, or the car seems sluggish, it may be due to exhaust pipe blockage causing poor exhaust flow, which reduces air intake and decreases engine power. 2. Frequent forced downshifting in automatic transmission: When exhaust pipe blockage reduces engine power, the driver may press the accelerator harder to speed up, causing the throttle to open wide. At this point, the car will control the automatic transmission to force a downshift based on the throttle's state.
Every time I get my car repaired, I always encounter a situation where the exhaust pipe is blocked. The most common issue is excessive carbon buildup inside the exhaust pipe, which completely blocks the pathway. Especially for older cars that have been driven for seven or eight years, the exhaust treatment device is particularly prone to clogging, making the car sluggish and consuming more fuel when started. Sometimes, the muffler rusts and breaks apart, and the iron debris can get stuck everywhere. To solve this, first go to the repair shop to dismantle the pipe and clean it. If that doesn’t work, replace the part with a new one. Remember to choose reputable gas stations when refueling, and drive more on highways to burn off deposits in the exhaust pipe, which can effectively prevent clogging.
