← TechnologyWhich outcome occurs when a gasoline direct injector nozzle experiences localized overheating due to carbon deposit buildup?
A)Uncontrolled pre-ignition of fuel✓
B)Fuel pump cavitation and failure
C)Reduced valve overlap and efficiency
D)Increased oil viscosity from fuel dilution
💡 Explanation
When injector nozzle overheats, autoignition temperature is reached because carbon acts as an insulator, triggering uncontrolled pre-ignition of fuel-air mixture before the spark. Therefore pre-ignition results, rather than pump cavitation, reduced valve overlap, or oil dilution which originate from different engine issues.
