Which problem intensifies when exhaust backpressure significantly exceeds turbocharger turbine inlet pressure under transient engine braking?

💡 Explanation

When exhaust pressure exceeds turbine inlet pressure, reverse flow occurs causing compressor surge because the pressure ratio across the compressor becomes unstable, disrupting the airflow. Therefore, compressor surge results, rather than overspeed, icing, or decomposition all requiring different initiating conditions.
