Which outcome occurs when a diesel engine’s turbocharger vanes become encrusted with combustion deposits?

💡 Explanation

Decreased vane movement affects geometry and increases the rotational inertia; boost response slows dramatically. This is due to **variable geometry turbo lag** causing the turbine performance to drop, therefore, a sluggish response results rather than improved performance under dynamic load changes.
