What is Sfc?

Specific Fuel Consumption (Sfc) refers to the fuel efficiency of an engine design, usually measured in terms of the amount of fuel used to produce a specific amount of work or thrust. It is most commonly defined for engines as pounds of fuel used per hour per unit of horsepower produced or thrust. Sfc is a critical measure for industries aiming to minimize fuel usage without sacrificing performance.

• Metrics and Measurement:
  • Mass or volume of fuel consumed per hour.
  • Calculated using equations specific to the engine type, e.g., thrust-based for jet engines or power-based for automotive engines.
