AIGF Exit Exam • Set 6 Question 2 of 30

Disadvantage of hybrid turbo charger is

✓

Direct Answer

Option D: heat generated is more

Hybrid turbochargers incorporating electrical power generation components experience higher thermal loads due to the integration of electromagnetic machinery within the housing. Proper cooling and lubrication management are critical to mitigate this heat, which is a known technical trade-off for the increased energy recovery efficiency provided by these systems.

All Options

doesn’t require lubrication

heat generated is less

doesn’t require cooling

heat generated is more (Correct Answer)
