  • 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

  • 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

  • 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 thrust — is a term used in Gas Turbine Engineering to show the relative bulk of a jet engine (e.g. turbojet, turbofan, etc) and is defined as the ratio: net thrust/total intake airflow. Low specific thrust enginesA modern civil turbofan has a low specific …   Wikipedia

  • Specific power — In engineering, the term specific power can refer to power either per unit of mass, volume or area, although power per unit of volume is more formally known as power density, and power per unit area as surface power density. [… …   Wikipedia
