← TechnologyWhich risk increases when ultrasonic atomization fuel injectors get contaminated?
A)Unstable engine combustion occurs✓
B)Bearing fatigue accelerates quickly
C)Volumetric efficiency decreases overall
D)Cylinder head warping increases
💡 Explanation
Unstable combustion follows injector contamination via fouling, because ultrasonic atomization depends on precise, high-frequency oscillations affected by impurities. This disrupts consistent fuel-air mixing, therefore combustion fluctuates, rather than consistent operation under stable injection.
