All heat engines utilize
A
Low heat value of oil
B
High heat value of oil
C
Net calorific value of oil
D
Calorific value of fuel
Correct Answer: Low heat value of oil
All heat engines utilize Low heat value of oil.In thermodynamics and engineering, a heat engine is a system that converts heat or thermal energy—and chemical energy—to mechanical energy, which can then be used to do mechanical work. It does this by bringing a working substance from a higher state temperature to a lower state temperature.
