Which outcome occurs when rapid thermal cycling exceeds design tolerance in high-pressure fuel injectors?

💡 Explanation

Accelerated fatigue crack propagation happens because of oscillating thermal stress exceeding the material's endurance limit; therefore, cracks develop, rather than remaining stable material, because cyclic stress causes cumulative damage, decreasing component lifespan.
