Which risk is amplified when a diesel engine's injector nozzle suffers from severe carbon fouling?

💡 Explanation

When the injector nozzle has carbon fouling, the spray pattern becomes uneven and erratic because the fuel's atomization is compromised, leading to localized hot spots on the piston and cylinder head. Therefore, higher cylinder head temperatures result, rather than altering EGR, spool-up, or fuel consumption, which are tied to different engine management mechanisms.
