Science

Which risk increases when a turbocharger's inlet temperature rises?

A)Compressor surge and flow instability
B)Increased bearing wear and friction
C)Reduced fuel economy efficiency ratings
D)Lean combustion oxygen flow reduction

💡 Explanation

Compressor surge risk rises due to elevated inlet temperatures and decreased air density. Therefore, mass flow decreases significantly and flow reversal occurs during pressure oscillation with the mechanism named aerodynamic stall, rather than other mechanical engine problems, because temperature critically affects gas density.
