← TechnologyWhich risk increases when turbocharger compressor blades experience excessive erosion?
A)Surge due to altered airflow dynamics✓
B)Thermal runaway due to adiabatic compression
C)Detonation due to increased cylinder pressure
D)Creep due to elevated turbine temperatures
💡 Explanation
When compressor blades erode, airflow dynamics are altered increasing turbulence leading to compressor surge because the pressure ratio fluctuates and airflow stalls. Therefore, surge risk is increased, rather than runaway, detonation or creep which require temperature or pressure limits to be exceeded in different engine components.
