In my experience, the technical data sheets (sometimes called "cut
sheets") that manufacturers provide on their websites have some of
the information that you need in order to create (or modify the
existing) data file.<br>
<br>
I have just been working on a much larger engine and found enough
data in the cut sheet that I was able to fill in the blanks with one
of the example files (the performance shown on the cut sheet and the
performance shown in the example file were similar enough that I
could make good guesses about the data that I didn't find yet.<br>
<br>
I would guess that much smaller engines might not have the same
kind of cooling requirements as the larger engines (maybe there
would be no aftercooler in a microCHP engine, for example). I would
spend some time looking online at manufacturer's websites to see if
you can find technical data for the engine that you are considering.
You might also use Type120, which is a much more basic model of an
IC engine/generator.<br>
Best,<br>
