What Causes Carbon Buildup in the Exhaust Pipe?

[Brenda]

Carbon buildup in the exhaust pipe can be attributed to the following reasons: Heavy Traffic: Heavy traffic is one of the causes of carbon buildup, as the engine may remain idling for extended periods, and frequent engine starts can also contribute to carbon deposits. Use of Low-Quality Gasoline: It is advisable to choose major state-owned enterprises like Sinopec or PetroChina to avoid low-quality fuel that may not burn completely, leading to carbon buildup. Poor Driving Habits: Ignoring the need for synchronization between engine RPM and throttle input, and avoiding prolonged driving with the engine at low RPM in high gears. Excessive Engine Load: Aggressive driving or long hours of continuous engine operation without adequate rest can accelerate carbon buildup, especially in vehicles that cover long distances daily.
