In an internal combustion engine, supercharging is the process of supplying intake air at a pressure
Show Hint
- higher than that of the ambient
- lower than that of the fuel
- higher than that of the fuel
- lower than that of the ambient
The Correct Option is A
Solution and Explanation
Supercharging increases the air pressure above ambient pressure to ensure a higher volume of air is injected into the engine cylinder. This improves the engine's efficiency and power.
Step 2: Analyze the options.
- (A) higher than that of the ambient: This is correct because supercharging increases the intake air pressure above the ambient air pressure.
- (B) lower than that of the fuel: Incorrect, as the intake air pressure is not related to fuel pressure in this context.
- (C) higher than that of the fuel: Incorrect, as the fuel pressure is not relevant to the supercharging process.
- (D) lower than that of the ambient: Incorrect, as supercharging requires the intake air pressure to be higher than the ambient pressure.
Thus, the correct answer is (A).

- Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process.
Reason (R): In an isothermal process, \( PV = \text{constant} \), while in an adiabatic process \( PV^\gamma = \text{constant} \). Here, \( \gamma \) is the ratio of specific heats, \( P \) is the pressure and \( V \) is the volume of the ideal gas.
