Question

Turbochargers are centrifugal compressors driven by the exhaust gas turbines.

(a) True

(b) False

The question was posed to me during an interview.

This intriguing question originated from Turbocharging in chapter Supercharging of IC Engine

Answer 1

Answer: (a) True

Explanation: Turbochargers are indeed centrifugal compressors driven by the exhaust gas turbines. The exhaust gases from the engine spin the turbine wheel, which is connected to the compressor wheel. As the turbine spins, it drives the compressor, which forces more air (or charge) into the engine’s intake manifold, increasing engine efficiency and power output. This process utilizes the energy from the exhaust gases that would otherwise be wasted.
