IMO the inverter generator is getting more power from the same displacement engine by spinning it faster. The eu2000i, for example, runs at a top engine speed of 5,000 rpm instead of being constrained to 3,600.
WOW - I did not realize the upper RPM was 5,000! For some reason I thought it was 4,000. I just cannot imagine running a small generator engine over 5,000 RPM and having it hold up without a full flow pressurized lubrication system along with stronger rods and bearing construction.
I've got one of those solid state single cylinder tachometers that you only need to hold close to the spark plug wire to measure RPM. It even has a built in divide-by-two switch if the engine has a waste spark or is a 2 stroke engine.
I need to get the Kipor out on the driveway and load it down to see what RPM it is running. The speed really picks up, but I was "thinking" it was 4K. Maybe not?
I'll let you know.
