Definitions for "Fuel Efficiency"
Keywords:  gallon, ton, amont, combustion, miles
Fuel efficiency measures the amount of fuel (in ton-miles-per-gallon) needed to move a vehicle of a certain weight a certain distance.
When a fuel is burned, the amont of useful output energy, expressed as a percentage of the theoretical energy content of the fuel. Fuel efficiency for a heating fuel is less than 100% to the extent that heated air is used in combustion and to the extent that exhaust venting is necessary. In other applications, fuel efficiencies are less than 100% partly because of waste heat generation.
The amount of work obtained for the amount of fuel consumed. In cars, an efficient fuel allows more miles per gallon of gas than an inefficient fuel.
