Question

If the speed of the engine is increased, the indicated power will ____________

(a) increase

(b) decrease

(c) remain same

(d) none of the mentioned

I had been asked this question in an interview for internship.

The doubt is from Measurement and Testing in chapter Measurements and Testing/Performance Parameters and Characteristics of IC Engine

Answer 1

The correct answer is:

(a) Increase

As the speed of the engine increases, the indicated power typically increases because the engine produces more power as the number of power strokes per unit of time increases, assuming other factors like the air-fuel ratio and load remain constant.
