Enter the specific fuel consumption in g/kWh (grams per kilowatt hour):
Enter the engine power in kW:
Enter the density of the fuel in kg/m3 (references: diesel — 850 kg/m3, petrol — 710 kg/m3):
Fuel consumption liters per hour (l/h) is:
How to calculate fuel consumption in liters per hour, if the specific consumption in g / kWh is known?
You can calculate by the formula:
Q = N * q / R, where
Q — (in l / h) maximum theoretical fuel consumption in grams per 1 hour of engine operation at maximum power;
q — (in g / kWh) specific fuel consumption for power N;
N — (in kW) engine power;
R — (kg / m3) fuel density.
