SOHC Posted September 14, 2014 Share Posted September 14, 2014 This idea has been around since internal combustion engines have been around, it was the only alternative fuel to ever completely replace petrol during WW2, I am having a crack at making a system, I need to find an oldish car to fit it to, something with a 4 or 6 cylinder with a distributor and carb and a manual transition, the older the better. I have mostly finished the generator and cyclone filter, water trap/cooler, I have another big cylinder I am going to make a filter witch uses dry grass/ wood shavings for a partial filter This is how it would look fitted to a car I have to make a lot of air tight hatches for cleaning etc. the fitting on the right is the shaker, I can put a spanner on that and rock the ash grate. 9 Quote Link to comment Share on other sites More sharing options...

SOHC Posted September 14, 2014 Author Share Posted September 14, 2014 I am building the more completed Imbert system as it has a bit more control, you see alot of crappy down draft versions around as they are pretty simple to make but are hard to control. I am building a Swedish V heath system where the build up of ash protects the metal hearth from the oxygen, my plan was to install it on my old Volvo not for road use just for a bit of funn 3 Quote Link to comment Share on other sites More sharing options...
danger Posted September 14, 2014 Share Posted September 14, 2014 Well, I'm interested. 2 Quote Link to comment Share on other sites More sharing options...
SOHC Posted September 14, 2014 Author Share Posted September 14, 2014 I have gathered alot of info I can't post it all, I was given the Volvo hearth and air nozzle sizing chart and I have a booklet from the NZDSIR from WW2 A friend on face book runs a 350 Chev on wood gas daily. Alot of work has gone into my generator already, I had to form a cone from 12mm plate witch was hard work, I just need to make the flange to bolt the wood hopper onto the firebox. I was hoping someone could give me some enthusiasm to finish this heap of shit 1 Quote Link to comment Share on other sites More sharing options...
SOHC Posted September 14, 2014 Author Share Posted September 14, 2014 The vehicles distrubtor needs to be controlled from inside the car like a manual advance retard, so it could be hocked up to an old choke cable and the clamp in the block needs to be modified to it can twist, and it needs an air control like a 2nd throttle butterfly upstream of the gas intent to control the air mixture. All up you would lose nealy half your engine HP as wood gas has such a low heating value, the heath is sized on the HP you use not the overall engine HP Quote Link to comment Share on other sites More sharing options...

SOHC Posted September 14, 2014 Author Share Posted September 14, 2014 I need to find some kind of blower that is made from steel to use for lighting up the system, it would be used to create the vacuum before the engine is started, don't holden HQS have a steel heater fan? 1 Quote Link to comment Share on other sites More sharing options...
Bangbug Posted September 14, 2014 Share Posted September 14, 2014 It'd be great if you could store woodgas, that'd make life much easier! Perhaps I should put some chemistry wizardry to the cause and give it a crack, unstable gases are usually best burnt pretty quick smart though I suppose. Or since this was done many many moons ago and we now have catalytic converters perhaps physics is the better tool to have a crack at it with. That'd at least get rid of the carbon monoxide which is probably one of the main problems, use up a little HC to convert to H2O (which is already present) and CO2 which is also present. 1 Quote Link to comment Share on other sites More sharing options...
SOHC Posted September 14, 2014 Author Share Posted September 14, 2014 Yes of you compressed wood gas a cylinder would only get you a cople miles up the road. The chemistry part is intresting. I dont fully understand it. Just that the hearth and nozzles must be mached to the engine or you carnt crack the tar and that will clog filters and stuff. There is some reaction in the hot char that forces a molecule of unburnab gas to share its oxygen and split into two molecules of burnable gas.

Threeonthetree Posted September 14, 2014 Share Posted September 14, 2014 Will check the HQ fan when I get home. You can have it if it's metal. They have a poor blade angle though. Quote Link to comment Share on other sites More sharing options...
SOHC Posted September 15, 2014 Author Share Posted September 15, 2014 That would be very much appreciated. Maby I could make a new blower center Quote Link to comment Share on other sites More sharing options...
Guypie Posted September 15, 2014 Share Posted September 15, 2014 I learnt about this about a year ago, was considering building one for a velobike but too much burn risk. Might still give it a go at some point, I never fornd half as much information on designs than you though, cool to see someone building one. 1 Quote Link to comment Share on other sites More sharing options...

I have the sizing carts and some more in-depth info if anyone is keen. There is a guy on the net with a moped running on gengas. Quote Link to comment Share on other sites More sharing options...
SOHC Posted September 15, 2014 Author Share Posted September 15, 2014 I tested my cyclone separator filter out with a vacum and handfulls of crap. It seems to remove everything apart from the fine dust. I have a 80 leater tank I was going ti make somekind of oil barth with a fiberglass filte. If I could get one of those oilbarth cyclone filters of some old earth moving mechaine would be good. Grit and moisture is the main problem with wood gas. An old guy was saying how on an old flathead 6 he ran no filter but had to remove the head and wirebrush everything often 1 Quote Link to comment Share on other sites More sharing options...
