Which outcome occurs when thermal expansion compromises injector nozzle sealing?

💡 Explanation

Uncontrolled fuel leakage affects emissions; incomplete combustion occurs due to poor atomization. The mechanism is dribble injection because thermal expansion reduces nozzle tightness, therefore increased unburnt fuel leaves the combustion chamber rather than creating a precise even combustion.
