![]() Therefore by dividing the fuel mass flow rate to the engine output power, we obtain the brake specific fuel consumption : \ Example – BSFC application in Scilab This parameter can not be used to evaluate the efficiency of the engine because it is not obvious how much power we can extract from the fuel. The amount of fuel used is usually measured on a dynamometer, as a mass flow rate, in kilograms per second. The keyword “brake” is related to the use of a dynamometer (electrical brake) to measure the engine parameters (fuel mass flow rate, torque, etc.).Īn internal combustion engine requires fuel and air to produce energy. ![]() ![]() In automotive applications, BSFC is used to evaluate the efficiency of the internal combustion engines (ICE). Brake specific fuel consumption (BSFC) is a parameter that reflects the efficiency of a combustion engine which burns fuel and produces rotational power (at the shaft or crankshaft). ![]()
