Don't forget you can also add an HHO setup to provide an extra bump to the woodgas. FEMA has a pdf you can get on the internet that gives the basics. Just make sure you adapt it to an Imbert as it creates higher temps needed to crack the tars. Also the wood does have to have a 20% moisture content or less. We get around new / green wood by having bought a nifty dehumidifier from GL that drops it to 2%, and then is placed outside to normalize.

Just think all those free wood chips from a tree company could be fueling your MV

I would just like to add that this works great in a GAS engine. The issue with a MV, in the case of a multi-fuel is the need for lube which is why 100% gas is not suggested. To get around this you would have to develop a simple system to drip UMO or another heavy lube directly into the fuel system but at a much lower rate, just enough to keep the system lubed. The HHO set up would do wonders to add the needed boost in power. I believe this system will work great on a deuce, and will actually be working on it for the heck of it. I already have HHO and it does work. I have the PDF from FEMA on how to build a wood gas generator for a truck, pm me if you want it (include you email). This PDF includes very specific instructions on how to build this. You could have one up and running in a month if your handy and have scrap metal laying around.

I have thought about playing with that, but I think roger-wilco-66 is right. for every day use it would be a pain. But if we ever do run out of gas, which I doubt, it is nice to know this alturnitive works too.

I think you would have to be a pickup to carry enough wood to run on to get home. At that point maybe steam cars would be more efficient.

Some were actually highly developed, this on recirculates some of the unburned CO2 (carbon dioxide) gases and claims to be up and running in 15 minutes with a pound for pound equivalent fuel milage to gasoline (I'm pretty sure that was the claim)....doesn't sound right...another check for the to-do-list...

Gentlemen,
I have been looking for a way to run an engine on wood for years. This thread has caught my eye. My family is always looking for a use for the TONS and TONS of mulch we grind each year and then have to give away or spread out in the woods and hope it rots. My brother has a grinder with a 350 HP engine turning the grinder. It's big. Please post any info you run across. I haven't had time to read all of this, but it looks like I have a new project.

Thanks,
Joe

Joe, you could use a set-up shown schematically here to run a genset.
The blower is only used during start-up. and the gas engine keeps the flow of air going thru the gasifier unit by the vacuum it creates.
I have briefly looked at propane hook-up for carburetors, which is very similar and the conversion is simple.
You'll find a number of sites on the web with building instructions. Build one from junk around your yard and with your welding skills.

Edit: Right click and open link in new window for full res.

Some interesting reading about the "Kalle" unit.
http://www.hotel.ymex.net/~s-20222/gengas/kg_eng.html

"Further experiments showed, that the best effect was gained by an adding of about 17% CO 2 to the gasifier, which, under the condition that all of that was turned into CO, results in a significant saving of charcoal."

"The temperature in the oxidation zone is in this way automatically regulated down to 1000°--900°C, and I can mention that it keeps itself remarkably constant around that even for different loads. Naturally, this is so because the CO 2 is added proportionally to the need for primary air."

"A radius of operation of 150km per filling is not uncommon for smaller cars."

"Correctly maintained, the gasifier can be started from cold condition in 30 seconds. It can stand 6--7 hours without having to be lighten again."

Just for you guys my favorite woodgas site: Woodgas for alternative energy - biomass hydrogen syngas fuel
I click mike LaRosa on the left and scroll down to his link to his galleries of self built woodgas powered trucks
Index of /~mlarosa/images/woodgas
he dosent write much but his pictures speak a thousand words and theres hundreds of em. This site really is a teasure trove of info. I enjoy woodgas as a hobbie myself and recently bought a 1/2 ton chevy 305 for a hundred bucks just for my Gasser project and hav taken designs from all over and drew up my own gassifier and hav been sourceing materials to build my own. another great site is KP
the website at Knowledge dosent show all the books on woodgas but they send u a catalog free when u buy a book which lists over 10 woodgas books Worth buying IMO. Maybe ill post my gassifier blueprints for u guys. Id like to see a dodge cucv converted camo + woodgas = Badass hehe
