उत्तर

Fuel efficiency is determined by its calorific value, which is the amount of heat energy produced on complete combustion of 1 kg of a fuel. The calorific value of a fuel is expressed in kJ/kg.

A good fuel should have high calorific value. That means it should produce a large amount of heat per unit mass.
