Fuel efficiency (or fuel economy ) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per ...
The fuel economy in aircraft is the measure of the transport energy efficiency of aircraft. Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel consumption and propulsive efficiency or thrust-specific fuel consumption. ...
Fuel efficiency refers to a measure of how much distance your car can travel with a specific volume of fuel.
red, imperial gallon The fuel efficiency of motor vehicles can be expressed in multiple ways: Fuel consumption is the amount of fuel used per unit distance; for example, litres per 100...
Autoblog covers news and reports about fuel efficiency.
Brake-specific fuel consumption ( BSFC ) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption ...

The annual fuel utilization efficiency ( AFUE ; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers. The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but i...
