Supercharging is the process of (a) Supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere (b) providing forced cooling air (e) injecting excess fuel for raising more load (d) supplying compressed air to remove combustion products fully. (e) raising exhaust pressure.

Answer :

Answer:

a)supplying the  intake of an engine  with air at a  density greater  than the density  of the surrounding  atmosphere

Explanation:

Supercharging  is the process of  supplying the  intake of an engine  with air at a  density greater  than the density  of the surrounding  atmosphere.

By doing this , it increases  the power out put  and increases the  brake thermal  efficiency of the  engine.It also  increases the  volumetric efficiency of the  engine.

So the our  option a is  right.
