Supercharging of I.C. Engine is essential for:

Supercharging is a method used to increase the power output of an engine by forcing more air into the cylinders. This process is particularly crucial for engines operating in environments where the air density is low.

Question:

Supercharging of I.C. Engine is essential for:

(a) Stationary engine/स्टेशनरी इंजन
(b) Marine engine/मेरीन इंजन
(c) Aircraft engine/एयर क्राफ्ट इंजन
(d) None of the above/ऊपर कोई नहीं

Correct Answer:

(c) Aircraft engine/एयर क्राफ्ट इंजन

Explanation:

Aircraft engines operate at high altitudes where the atmospheric pressure and air density are significantly lower than at sea level. The low density of air means that a standard engine would take in a smaller mass of oxygen, leading to incomplete combustion and a loss of power.

Supercharging compensates for this by compressing the thin atmospheric air before it enters the engine cylinders, effectively increasing the air density. This ensures that the engine receives a sufficient mass of oxygen for proper combustion, allowing it to maintain its power output and performance at high altitudes.

Key Point:

Supercharging is used in various applications, but it is essential for aircraft engines to overcome the effects of low atmospheric pressure at high altitudes. Without it, the engine would not be able to produce the necessary thrust for flight.

Exam Tip:

Remember that the primary purpose of supercharging in aircraft is to counter the decrease in air density with increasing altitude, thereby maintaining engine power.
