Generator Long hours Low load


Homelite 7.JPGHomelite 8.JPGHomelite 9.JPGHomelite 10.JPGHomelite 13.JPGThis by far would be the worst carbon deposits iv ever seen in a small 4stroke engine. It got to the point where the engine couldnt be pulled over top dead center at all. It wasnt using oil & not blowing blue smoke. In fact the in side of the engine is very clean. This generator has had long hours with a light load.

My solar panel has done long hours with a low load and not a sign of carbon . . . and no fuel either. Or noise.
Cheers, Tony

Solar doesnt cut it were this person works. He also runs a 3Kv diesel generator for large cool rooms.

Hi dogbox, I dont know, it was very hard carbon as it stoped the piston from reaching TDC & was imposible to turn over that point.

Out here in the country you buy fuel where ever you can get it. Bit different to city fuel buying.

A lot of gen operators never seem to load up the genny and think that a 3 KVA unit is required to power a light and fridge so the poor old thing just lumbers along and Wham O the genny gives up they need a load to function as the specs say they should

I recall from a previous life when I was gainfully (?) employed that we often used "dummy load" resistors or otherwise take steps to provide a load for generators especially those with turbochargers fitted (diesels in the 25 - 50 kva range)

Digressing slightly I know, Daryl, but in the last couple of days I came across some comment that these newer (sine wave) inverter type generators may have issues when operating into loads with poor power factors (0.7 or less)....have you come across this at all?

Jim

PS: I don't wish to start a myth as this may be a "furphey"

Hi Jim, Havent heard of that yet. Any idea what its suposed to do to them? Re loads on generators I tend to run flood lights when there needs to be a reasonable load.

 The following is from the Setec - Jayco power supply website (it's a downloadable pps file)
