Question

Anti-freeze mixtures are added to fuel in extreme winter seasons to lower its freezing temperatures below the danger point.

(a) True

(b) False

I have been asked this question during an interview.

This is a very interesting question from Liquid Cooling Systems topic in section Heat Rejection and Cooling of IC Engine

Answer 1

The correct answer is:

(b) False

Anti-freeze mixtures are typically added to the coolant (not the fuel) in liquid cooling systems to prevent the coolant from freezing in extremely cold conditions. They lower the freezing point of the coolant, ensuring it remains in liquid form and continues to function effectively in the engine's cooling system. Anti-freeze does not typically get added to the fuel.
