Which outcome occurs when a turbocharger malfunctions, causing excessive air intake in a modern gasoline engine?

💡 Explanation

When a turbocharger causes excessive air intake, lean combustion occurs in the cylinders because high air volume causes high Air/Fuel ratio, leading to elevated combustion temperature. Therefore increased NOx results, rather than rich combustion, detonation, or reduced hydrocarbon emissions which require different fueling imbalances.
