← TechnologyWhich outcome occurs when rapid fuel injector valve actuation causes sustained oscillations in a vehicle's fuel rail?
A)Harmonic pressure wave amplification✓
B)Uniform fuel-air mixture enrichment
C)Minimized hot-start injection delay
D)Increased catalyst light-off efficiency
💡 Explanation
Harmonic pressure wave amplification results from resonant frequencies excited by the fuel injector’s rapid on/off action, because this action sets up standing waves and pressure spikes increase, therefore damaging/disrupting smooth fuel delivery rather than the alternatives relating to optimized burning.
