Which outcome occurs when turbocharger bearings experience oil starvation in an internal combustion engine?

💡 Explanation

When oil starvation occurs, inadequate lubrication causes increased friction and rapid heat buildup because hydrodynamic oil film fails, resulting in bearing material welding and shaft seizure. Therefore, shaft seizure occurs, rather than surge, knock, or cutoff require different specific sensor failures influencing control algorithms.
