[Gasification] ideal wood gas engine

[Greg Manning]

 Hi Kevin,

 I think you are "above average". A 2.5L 150 CID engine on woodgas at
1800rpm IMO is only 15 "practical" HP.

 Pristine gas evolution might achieve your 21.4 HP, but I would factor low,
instead of high, the small savings in fuel is no where the losses, if the
generator "browns out" taking all the appliances and electrical goodies with
it.

I would still shoot for a 292 CID engine for 20 HP at 1800 RPM.

 Oh, BTW, even a really "good" used engine would be only 80% of it's "New"
Hp rating on gasoline, again, I would factor more CID to compensate for a
used engine.

 Greg

Dear Charles

Your stated need is for "about 20 HP" at 1,800 RPM

You should be able to get about 21.4 HP with an engine of 2500 CC (153 Cubic
Inches), burning about 19 kG/Hr (42 Lbs/Hr)

It would be very helpful if others could comment on the other aspects of an
engine.... in particular, the Ignition system, whether Distributor or
"Computer Controlled", and the implications of using a Fuel Injected engine,
rather than a carburetor engine.

Best wishes,

Kevin
