Any guess as to how my genset's fuel efficiency?

 Rated power: 4.0KW
Engine: Acme Motori 1 cylinder Diesel
Volume: 370CC
Engine power at the shaft: 5.7 KW

Any thought of how many gallons per hour it could be using at

    - idle
    - half load
    - full load

thanks...

i

  fill the tank to the topgo out there an hour later with a jug full of diesel
note the measurements on the side  fill it up to the brim again take note of
the amount left
take full amount away from the whats left amount   and there you have it
and ya done it all ya self

Seems good to me, I put a standard house Watthour meter on ours and
took readings over a few hours and then once a day. I then plotted a
x:y scatter in a spreadsheet.

What I would like would be a Wattmeter with data logging.

I suppose the photo voltaic users use data loggers on their panel
outputs?

Wouldn't using a watthour meter and keeping track of how much fuel you burn
give you a good average?  Seems like it would give you the 'real-world'
efficiency with whatever your varying load is like.  I kind of like the idea
of having a watt-hour meter in the system.

Yes for most purposes this must be good enough, we did it for a few
weeks. However it depends on someone logging the figures daily. In our
case the teaching staff were not willing to do this, so a simple data
logger with inputs of VA, Hz, kW and litres/sec would have been
interesting, especially as the generator was blamed for a lot of IT
problems.

When we installed the genset we expected to be in the low 30%s
conversion, it was eye opening to see we only averaged 20%. If we had
better figures I may have been able to demonstrate how better loading
of the genset may have offered cost savings despite increased capital
costs.
