← ScienceWhich consequence results when excessive friction impedes turbocharger's Brayton cycle?
A)Increased compressor surge probability
B)Decreased turbine adiabatic efficiency
C)Elevated charge air temperatures exiting✓
D)Reduced intercooler pressure differential
💡 Explanation
Higher friction generates more heat from parasitic losses within the compressor. Because the compression work increases to overcome friction the 'isentropic efficiency' (ideal compression scenario) drops, and charge temperatures at the outlet rise, rather than other pressure-related changes.
