← ScienceWhich consequence usually follows cavitation within diesel injectors?
A)Erosion increases; fuel atomization declines✓
B)Overheating ceases; power efficiency increases
C)Efficiency increases; fuel density changes increase
D)Lubrication improves; injector lifespan expands
💡 Explanation
Cavitation causes material erosion via the **formation and collapse of vapor bubbles**. Because pressure fluctuations induce this mechanism within the injector, erosion increases; therefore fuel atomization ability declines, rather than injection improving, due to damage.
