Mar 29, 2024 · Calculation Example: The specific fuel consumption (SFC) of a diesel engine is a measure of its fuel efficiency. 853 @ 15. It is defined as the mass of fuel consumed per unit of power output over a unit of time. Mar 24, 2025 · The fuel consumption can be calculated using the formula FC = SFC * P * t, where FC is the fuel consumption, SFC is the specific fuel consumption, P is the power output, and t is the operating time. The formula divides the product of the specific fuel consumption in kilograms per kilowatt hour and the output power by the density of diesel in kilograms per liter, which is Specific Fuel Oil Consumption (SFOC) is a measure of the fuel efficiency of a marine engine, expressed as the mass of fuel oil consumed per unit of power output. Jan 15, 2025 · The BSFC (Brake Specific Fuel Consumption) Calculator allows you to calculate brake specific fuel consumption to evaluate the efficiency of diesel, gasoline, and turbine engines. The choice of Specific Gravity of Diesel = 0. The engine power (in bhp or KW) can be calculated from the Indicator diagram or from Fuel Pump Index method or from Turbocharger speed. May 1, 2024 · Popularity: ⭐⭐⭐ Fuel Consumption of Diesel Engine This calculator provides the calculation of the fuel consumption of a diesel engine for a given operating time. Brake thermal efficiency of the engine is 30% with a fuel of CV of 40 MJ/kg and specific gravity of 0. Specific fuel oil consumption= Mass of fuel consumed per hour/break power in that particular hour Detailed Specific Fuel Oil Consumption calculation for diesel engine SFOC Calculation This document provides instructions for calculating specific fuel oil consumption (SFOC) in different conditions: 1) It describes subtracting a safety tolerance of 5% and making corrections for ambient conditions like temperature and pressure using a beta calculation formula. Online calculator and detailed explanation. Learn to apply diesel generator fuel consumption per hour formula and cost per kWh. A four-cylinder four-stroke diesel engine has bore of 100 mm, stroke of 120 mm and piston speed of 10 m/s. Mar 28, 2022 · I have a marine diesel engine, and I'd like to calculate the approximate fuel consumption based on the size of the engine, at a given number of RPM - specifically for the cruising recommended cruising RPM of 2880 - 3240. It covers topics like air-fuel ratio, piston displacement, indicated power, brake power, thermal efficiency, specific fuel consumption, and waste heat recovery. 27 kg / kW-hr. Nov 18, 2025 · Specific Fuel Consumption (SFC) is the measure of how efficiently an engine uses fuel to produce power. It is influenced by several factors including engine design, load conditions, and maintenance status. 5°C is quite arbitrary and will vary from time to time with different grades of diesel and in different countries; while some engine manufacturers may even specify a different specific gravity for their own tests, presumably for very good reasons. Explanation: The unit of specific fuel consumption is given by kg/kW-hr. Mar 19, 2025 · Calculate diesel generator fuel consumption in L/hr (and cost/kWh) by load. Brake Specific Fuel Consumption (BSFC): An increase in BSFC is generally observed with the addition of 2-pentanol to both diesel and biodiesel blends. s f c = F u e l c o n s u m p t i o n p e r u n i t t i m e p o w e r The specific fuel consumption per kW-hr for a diesel engines is very close to 0. The formula to calculate the fuel consumption on a duty point of the pump: L/h = Px BSFC÷835 P = Pump power in kW This document provides a formula for calculating fuel consumption in liters per hour (L/H) given the specific fuel consumption in grams per kilowatt hour (g/KWH) and the output power in kilowatts (kW) of a diesel engine. Explanation Calculation Example: The specific fuel consumption (SFC) is a measure of the fuel efficiency of a combustion engine. The calculation was carried out and graphical dependencies of fuel consumption were obtained when special equipment was operated using the example of the KrAZ-6322 car. May 28, 2025 · Specific Fuel Consumption (SFC) is a critical metric indicating fuel efficiency of the diesel generator. of fuel used per hour ÷ The document discusses formulas and concepts related to diesel power plant performance. Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. Brake specific fuel consumption is the ratio of a mass flow rate of the fuel supplied to the engine to the brake power obtained at a crankshaft and it Jun 12, 2025 · Learn how to calculate the fuel consumption of a diesel generator based on load, power rating, and efficiency. A lower BSFC value is MORE efficient.
