Which outcome occurs when thermal expansion surpasses designed clearances within a gasoline direct injector?

💡 Explanation

When thermal expansion exceeds clearances, the fuel injector needle binds because excessive heat causes components to expand beyond their operational tolerances, restricting movement. Therefore, fuel flow is reduces, rather than increased emissions, temperature or detonation, which require altered fuel spray patterns or mix ratios.
