← TechnologyWhich consequence results when hot gas recirculation compromises turbocharger efficiency?
A)Excessive back pressure intensifies surging
B)Increased detonation reduces engine timing✓
C)Pre-ignition accelerates turbine wear
D)Intercooler icing restricts airflow rates
💡 Explanation
Increased detonation will reduce engine timing because hot gas recirculation raises intake temperature, therefore leading to uncontrolled combustion events, rather than efficient compression ignition. Surge is related to compressor stall.
