Which outcome occurs inside internal combustion engine cylinders with excessive carbon buildup?

💡 Explanation

When carbon builds up excessively, its insulating properties causes hotspots leading to pre-ignition, wherein the fuel mixture ignites before the spark plug fires. Therefore, pre-ignition results rather than increased EGR, or altered valve timing parameters, each caused via separate mechanisms.
