Which outcome occurs when exceeding compressor speed limits in turbochargers?

A)Compressor surge creates reverse flow
B)Increased intercooler heat exchanger efficiency
C)Turbine blade fatigue life extension
D)Reduced lubricating oil consumption rate

💡 Explanation

Compressor surge results when the compressor cannot add enough energy to overcome downstream pressure, because flow reverses at the blades causing instability. Therefore, surge happens rather than increased efficiency because the reversed flow stops optimum pressure increases.
