What are exhaust system coke deposits?

Exhaust system coke deposits primarily refer to excessive carbon buildup that occurs in the exhaust system of an engine. These deposits form as a result of incomplete combustion or the degradation of lubricating oils at high temperatures within the exhaust tract. The carbon compounds that are not fully burned out accumulate over time, creating solid deposits known as coke.

This accumulation can lead to restrictions in the exhaust flow, negatively impacting engine performance and efficiency. It may also contribute to overheating, as the deposits can insulate hot gases in the exhaust system, leading to increased temperatures within the engine components. Monitoring and addressing coke deposit buildup in the exhaust system is crucial for maintaining optimal engine performance and longevity.
