← TechnologyWhich outcome occurs when a diesel engine's fuel injector nozzles experience carbon fouling?
A)Increased exhaust gas recirculation rate
B)Decreased knocking from premature ignition
C)Elevated cylinder temperatures due to uneven burning✓
D)Reduced turbocharger efficiency from lower EGT
💡 Explanation
When diesel injector nozzles are fouled by carbon deposits, the spray pattern becomes irregular and atomization is reduced because of disruption of flow, leading to incomplete and uneven combustion. Therefore elevated cylinder temperatures occur due to incomplete combustion, rather than altering EGR, or changes in knocking or turbocharger efficiency that involve different mechanisms.
