BRAKE SPECIFIC FUEL CONSUMPTION Meaning and
Definition
-
Brake Specific Fuel Consumption (BSFC) is a measurement used in the field of automotive engineering and transportation to evaluate the efficiency of an internal combustion engine in terms of fuel consumption. It refers to the amount of fuel consumed by an engine to produce a specific amount of power or torque output.
BSFC is typically measured in units of mass of fuel consumed per unit of power output, often expressed in grams per kilowatt-hour (g/kWh) or grams per horsepower-hour (g/hph). This measurement allows for comparisons between different engines and provides valuable data for analyzing their efficiency.
A lower BSFC value indicates a more efficient engine, as it means the engine requires less fuel to generate a certain level of power or torque. High BSFC values, on the other hand, imply that the engine is less efficient and consumes more fuel to produce the same amount of power.
BSFC is commonly used in the design and optimization of engines, as well as in performance analysis and fuel economy evaluations. Manufacturers strive to develop engines with lower BSFC values to enhance energy efficiency, reduce emissions, and improve overall sustainability.
In summary, Brake Specific Fuel Consumption is a measurement that quantifies the fuel efficiency of an internal combustion engine, comparing the amount of fuel consumed to the power or torque it generates.
