How to Clean a Clogged China V Exhaust Pipe?
2 Answers
To resolve a clogged car exhaust pipe, the solution is to use tools to remove the obstructing object. The impacts of a clogged car exhaust pipe include: 1. Difficulty in accelerating, with challenges in increasing engine RPM and vehicle speed; 2. Frequent forced downshifting in automatic transmission vehicles; 3. Reduced engine power and excessive exhaust emissions; 4. Engine shaking, illuminated fault light, and frequent stalling; 5. Continuous temperature rise in the exhaust pipe, potentially reaching the ignition point of nearby components and leading to spontaneous combustion. Maintenance methods include: 1. Preventing water ingress inside the exhaust pipe; 2. Applying rust-proof oil inside the exhaust pipe; 3. Regularly inspecting the condition of the exhaust pipe.
Last time my exhaust pipe was clogged, and the car had no power when accelerating. I thought the engine was broken. Later, the mechanic said it was a problem with the particulate filter in my China V emission standard vehicle. He taught me to use the high-speed regeneration method: drive on the highway in S mode, maintain over 3000 RPM for 40 minutes to raise the exhaust temperature and burn off the carbon deposits. Usually, I should avoid refueling at small gas stations and regularly add fuel system cleaner. Frequent short trips while stationary can easily cause clogging. I tried it twice, and it cleared up, saving me a lot more money than disassembling and cleaning—about a thousand bucks in repair costs. But if regeneration doesn’t work after several attempts, there’s an 80% chance you’ll need to disassemble and clean or replace the catalytic converter, which requires professional equipment to handle.
