← TechnologyWhich consequence results when insufficient oil reaches a turbocharger?
A)Bearing failure and shaft seizure✓
B)Compressor surge and impeller damage
C)Increased exhaust backpressure and reduced power
D)Fuel dilution and engine knocking
💡 Explanation
Bearing failure and shaft seizure results from oil starvation because inadequate lubrication leads to increased friction and heat within the turbocharger's internals. Therefore, the turbocharger seizes rather than operating efficiently; insufficient oil doesn't directly cause compressor surge issues.
