Question

How does the supercharger increase power output?

(a) By increasing the charge pressure

(b) By increasing the charge temperature

(c) By increasing the speed of the engine

(d) By increasing the quantity of fuel admitted

This question was addressed to me by my college professor while I was bunking the class.

I'm obligated to ask this question of Supercharging of IC Engines topic in chapter Fuels & Supercharging of I.C of Automobile Engineering

Answer 1

Right answer is (a) By increasing the charge pressure

The best I can explain: The supercharger increases the power output of the engine by increasing the charge pressure. The brake of the engine depends on the brake mean effective pressure.
