How to calculate fuel average consumption hours/liter?
that's not how fuel consumption is measured, unless you were to drive at the same speed for an hour. It is measured in MILES or KM per liter. That way you just fill your gas tank, pay attention to how much is in it, look at your odometer, and see how many miles until your tank runs out. Then divide number of miles by liters in your tank.
You just take the number of hours the generator was running, and the number of liters of fuel it used, and then divide. If it runs for 10 hours on 2 liters of fuel, then its average consumption is 5 hours per liter (10 divided by 2).
Fill your tank to the very top, all the way to where it is almost overflowing. Then run the engine for 1, 2, 3, 4, 5, hours, or however long you want but for simplicity sake do it at an least an hour or a whole 60 minutes for easy division (remember that a generator will use more fuel when it is being taxed by running something off of it than it will while simply running with nothing using its power). Then turn the engine off and refill the tank to the exact amount you originally filled it to while at the same time making sure you know exactly how much fuel you are putting in (use a measuring cup). Once you know how much fuel it takes to fill the tank to the point you originally filled it you will have the basis for your equation which will be: amount of fuel consumed (the amount you replaced) divided by the time the engine ran.
Divide the number of hours the motor ran by the number of gallons used. ex. 100 hours run time divided by 5 gallons used 20 hours per gallon. Hint - sometimes if you oversimplify your question, people don't understand what information you are asking for.
