Question

What is the purpose of the supercharger?

(a) To increase the pressure

(b) To increase the speed of the engine

(c) To increase the gear ratio

(d) To increase the cooling rate

I had been asked this question in an online interview.

My query is from Supercharging of IC Engines in section Fuels & Supercharging of I.C of Automobile Engineering

Answer 1

The correct option is (a) To increase the pressure

The explanation: The purpose of the supercharger is to increase the pressure of the charge. Brake power = \(\frac{brake\, mean\, effective\, pressure \,X \,swept\, volume\, X\, no.of \,cylinder\, X\, no.of \,power \,strokes}{60000}\) . From the formula, by increasing the brake mean effective pressure brake power can be increased.
