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 divided by the power produced. … See more To calculate the actual efficiency of an engine requires the energy density of the fuel being used. Different fuels have different energy densities defined by the fuel's heating value. The See more Any engine will have different BSFC values at different speeds and loads. For example, a reciprocating engine achieves maximum efficiency when the intake air is unthrottled and the engine is running near its peak torque. The efficiency often reported for a … See more • Reciprocating engine types • HowStuffWorks: How Car Engines Work • Reciprocating Engines at infoplease • Piston Engines US Centennial of Flight Commission See more BSFC numbers change a lot for different engine designs, and compression ratio and power rating.
