How to Calculate Disel Fuel Consumption

07/10/2014 11:23 AM

Dear All

How can I calculate diesel fuel consumption for a 245 KW gen set?

The result must be in liters per hour!

Then it is fuel volume over time!

With a flow meter calibrated for diesel

With a clock, a tape measure and a dipstick, of course.

Oh - there is another way. Divide the fuel volume delivered by the interval since the last one, Boss. All you need are the delivery driver's dockets.

Take your bill for the diesel fuel you bought when you filled your tank and divide the bill total (minus tax) by the price per gallon, or liter. This number will be the total gallons you used if it was filled previously.

See if the manual gives the fuel consumption rates for various levels of generator loading. You will have to estimate how the load may vary, unless known to be steady.

Fill the tank. Weigh gen-set.

Start and run gen-set. Note time run and load.

Do this till the tank is empty.

Calculate usage by using density of fuel.

Use a totalizing fuel oil delivery meter. The thing that the driver uses to tell how much he has delivered. Put the meter in the fuel line supplying the fuel from the tank to the engine. Read the start reading on the meter and the start time. Read the end reading of the meter and the finished time. Subtract the end from the start and that is the quantity used. Subtract the start time from the end time and that's the time period.

Fuel used/time period = fuel consumption of volume per KW

Nice thing about this set up is you can also determine the flow at any time by reading the flow meter only .

Good Luck, Old Salt

Which one do you need, the actual or the theoretical calculations?

They probably need the actual calculation from on site usage. They probably think that they want the theoretical calculation but they obviously do not have the background to attempt this useless calculation. To attempt this calculation requires an excellent understanding in Newtonian Physics, mechanical engineering theory, diesel engine design (both theory and the actual engine used), electrical engineering, power distribution, the anticipated electric load and the trivial factors that effect all of these of the weather. As this partial (I'm sure I missed something) list should show there are many variables that will change the theoretical fuel consumption rate. Many of these variables can be minimized once one understands how to properly apply the mathematics of statistics and random process variables.

The simplest and most practical thing they should do is to not calculate anything but to look for the manufacturer's propaganda on fuel consumption rates. This will probably be available at their web site or the operators manual. [RTFM]

I concur RedFred. You are correct in your assessment, and that was why I raised the question to the OP. I'm not sure if the OP is aware of the big difference between the two?

If you have the actual, why would you need the THEORATICAL?

ebjoe -

Is it of any significant to you to know both? What will you do when you realized that the results are NOT going to be the same no matter what you do?

These are the practically measuring systems

If the diesel tank seperate from the diesel generator,arrange a flow meter.

other wise using dipstic system also u can measure the diesel consumption hourly based.

and diesel consumption depends on the load on the DG set means full load DG consumed

diesel more than the DG at 80% laod on the dg set.

Fill up 1 litre of fuel in to the generator and see how long it take to run before is run out of fuel again.
