Question

(a) True

(b) False

I got this question in an interview for internship.

This question is from Total Engine Friction topic in portion Engine Friction and Lubrication of IC Engine

Answer 1

The correct answer is:

(b) False

Exhaust throttling loss is related to the restrictions in the exhaust system, particularly from components such as the exhaust valve, exhaust manifold, and exhaust pipe. The statement describes intake throttling losses, which are caused by restrictions in the intake system, such as the air cleaner, carburetor venturi, throttle valve, and intake manifold.
