Which risk increases when a turbocharger in a diesel engine experiences excessive exhaust backpressure?

💡 Explanation

When exhaust backpressure exceeds design limits, turbine speed decreases, potentially causing compressor surge because pressurized air reverses flow through the compressor, damaging the impeller blades. Therefore, impeller damage increases, rather than converter failure, bearing wear or injector clogging which happen from different causes.
