Question

6) Which ONE of the following statements is TRUE about supercharging?
A) The density of intake air increases.

B) The volumetric efficiency decreases

C) The mean effective pressure decreases

D) The engine output decreases for the same displacement volume.​

Answer 1

the volumetric efficiency decrease

Answer 2

SUPERCHARGING

Explanation:

• The true statement about supercharging is that the density of intake air increase. So, option A is correct.  

• Supercharging is the mechanism of supplying air in the engine so that  the intake of engine with air at a density greater than the density of the atmosphere, then each intake cycle of the engine receives more oxygen.
• Due to the addition of oxygen, it burns more fuel and generates more power.

• Supercharging compensates for the reduced atmospheric pressure at higher altitudes in aircraft piston engines.
• The development of the gas turbine, which requires a constant flow of air and fuel, resulted in the turbosupercharger, or simply turbocharger, a centrifugal blower operated by a small gas turbine enabled by exhaust gases from the engine cylinders.
