What is Specific Fuel Consumption ?
The specific fuel consumption in kilograms per kilowatt hour is typically used to describe an engine’s fuel consumption characteristics. This crucial variable demonstrates how well the engine performs. It is inversely related to the engine’s thermal efficiency.
sfc = Fuel Consumption per unit time / Power
The abbreviations bsfc and isfc, which stand for Brake Specific Fuel Consumption and Indicated Specific Fuel Consumption, respectively, refer to specific fuel consumption based on brake power BP and Indicated power IP.
