Which outcome occurs when a turbocharger's compressor increases air density beyond engine's fuel injector capacity?

💡 Explanation

When compressed intake air exceeds available injected fuel, the air-fuel mixture becomes lean, causing uncontrolled combustion and detonation, known as engine knocking. Therefore knocking results, rather than reduced EGT, cooler activation, or catalyst damage which would stem from rich conditions or overheating.
