← TechnologyWhich outcome occurs when excessive heat accumulates near a turbocharger's lubrication lines?
A)Oil thermal breakdown risk increases✓
B)Increased compressor impeller efficiency
C)Improved turbine housing heat dissipation
D)Decreased intercooler condensation issues
💡 Explanation
Thermal decomposition risks increase because oil viscosity decreases at high temperatures, causing the **Arrhenius equation** rate increase which accelerates oil breakdown. The oil loses lubricating properties; therefore, bearing wear increases, rather than the other effects which involve turbocharger performance.
