Hello Pete,
don’t get it wrong. It doesn’t mean the physically correct formula!
It is a rule of thump for the specific wood or charcoal consumption. So for an engine output of 1 horse-power for one our, you can estimate a consumption of 0.8 to 1 kg wood or 0.4 to 0.5 kg charcoal.

I cannot read any German but very often I can puzzle through topic words and short descriptions if they are in context. I was surprised how many of the diagrams don’t really need labeling to be of use. Very good diagrams covering air styles, nozzles, lids and other configurations. My one concern is that the author might have included a drawing of what not to do with a stern warning in German. I will add my thanks to the others for the availability of another resource.

As far as I overlooked it, there is more a discussion about proven or current designs. Of course with pros and cons.
No bad examples what not to do.
If you have a question about a drawing in particular, just give the page number and I can give some details and translate the legend.

Hello Til,
Thank you for uploading the book. It is excellent. Sadly - my German is not, I did note that on page 378 App. 105 is a nice cross section view of the principal we have used to convert the low speed Lister type diesel engines with a pre-combustion chamber to dual fuel - diesel and spark ignition.
Best regards,
Ron Ohler

Hello Giorgio,
pleasure to help and to share knowledge. I try to collect old documents about woodgas, but this book is really the best overview of the past I have ever found. You named it: Swiss perfection 
Thank you for your threads about your own builds. I like them a lot. Hopefully I can start my own project soon, but in the moment rebuilding an old house take all my attention an spare time.
Regards,
Til

Very unfortunate for me, I tried Opera, Microsoft Edge, Google Chrome, and Firefox and all of them give the same Invalid URL message once the page loads. Not sure why it won’t work.
