Question

What are the systems that use a turbocharger to maintain an engine’s sea-level power output is known as?

(a) CRDI engine

(b) Multi-air engine

(c) TDCI engine

(d) Turbo-normalized engine

I had been asked this question during an interview for a job.

Asked question is from Petrol Engine Fuel Supply System topic in section Exhaust System & Petrol Engine Fuel Supply System of Automotive Engine Design

Answer 1

The system that uses a turbocharger to maintain an engine's sea-level power output, especially at higher altitudes, is known as a turbo-normalized engine. This system compensates for the lower air density at higher altitudes by using the turbocharger to maintain engine performance similar to that at sea level.

Final Answer:

(d) Turbo-normalized engine.
