  • Specific fuel consumption (thrust) — Specific fuel consumption, often shortened to SFC, or TSFC is an engineering term that is used to describe the fuel efficiency of an engine design with respect to thrust output. It allows the efficiency of different sized engines to be directly… …   Wikipedia

  • Brake specific fuel consumption — (BSFC) is a measure of an engine s efficiency. It is the rate of fuel consumption divided by the power produced. BSFC is specific for shaft engines such as reciprocating engine. The BSFC Calculation (in metric units) To calculate BSFC, use the… …   Wikipedia

  • brake-specific fuel consumption — The weight of fuel burned per hour to produce a given amount of brake horsepower in a reciprocating engine. Normally, BSFC is expressed in pounds of fuel burned per hour for each brake horsepower the engine develops …   Aviation dictionary

  • thrust-specific fuel consumption — A measure of the fuel efficiency of a turbojet or turbofan engine. It is the mass of fuel burned per hour for each unit of thrust produced …   Aviation dictionary

  • fuel consumption — The amount of fuel used, expressed in miles per gallon in Britain and the USA, whereas the international measure is litres per 100 kilometres. The US term is fuel mileage. Also see average fuel consuption specific fuel consumption …   Dictionary of automotive terms

  • Fuel economy-maximizing behaviors — (also known as green driving) describe techniques that drivers can use to optimize their automobile fuel economy. The energy in fuel consumed in driving is lost in many ways, including engine inefficiency, aerodynamic drag, rolling friction, and… …   Wikipedia

  • Fuel efficiency — is a form of thermal efficiency, meaning the efficiency 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… …   Wikipedia

  • Specific impulse — (usually abbreviated I sp) is a way to describe the efficiency of rocket and jet engines. It represents the impulse (change in momentum) per unit of propellant. The higher the specific impulse, the less propellant is needed to gain a given amount …   Wikipedia
