Which outcome occurs when fuel injectors in a diesel engine experience excessive carbon buildup?

💡 Explanation

When carbon builds up in fuel injectors, the fuel spray pattern becomes uneven and obstructed because the buildup alters the nozzle geometry impairing atomization, leading to incomplete combustion in specific cylinder areas. Therefore localized cylinder overheating results, rather than knocking, viscosity changes, or turbine speed increase, because the fuel is not burning properly and cooling the engine evenly.
