Question

____________ of fuel energy is wasted as heat energy to friction, pumping and dynamic movement.

(a) 7%

(b) 9%

(c) 16%

(d) 38%

The question was asked by my school teacher while I was bunking the class.

I need to ask this question from Turbocharging in chapter Supercharging of IC Engine

Answer 1

Answer: (b) 9%

Explanation: Around 9% of fuel energy is typically wasted as heat energy due to friction, pumping losses, and dynamic movement in an internal combustion engine. These losses occur because of the resistance from moving parts, friction between components, and energy required to move air and exhaust gases through the engine. These factors contribute to a reduction in overall engine efficiency.
