Understanding Excessive Carbon Buildup on Spark Plugs: Causes and Solutions
Explore the causes of excessive carbon buildup on spark plugs and how to prevent it with regular maintenance.
225 views
Excessive carbon buildup on spark plugs can be caused by rich air-fuel mixture, oil leakage into the combustion chamber, or poor ignition system performance. A rich mixture results from too much fuel and not enough air, leading to incomplete combustion. Oil leaks can occur due to worn valves or piston rings. Regular maintenance, such as checking and replacing air filters and ensuring proper fuel mixture, can help prevent this issue.
