Hello from Sweden

The first 1,5 year i used this filter the piping and cooler was totally clean, the water in cooler and in condensate catcher near engine was clear too.
Anyways there was always soot after the butterfly valve in mixer, and some in intake, read somewhere that it’s almost impossible to not get some soot where there is a pressure drop.
As for the stainless “fabric” it’s something i really want to try, I dont think it’s to stiff to work, as im going to change out my glass-fibre fabric, the stainless stuff is what im looking for.

What do you think about this, what size of squares do you think one would have?
This is what my intake looks like after about 30-40 miles, was yours something like that?

" . . . read somewhere that it’s impossible to not get some soot where there is a pressure drop."
So true.
Pressure drops are flow turbulences areas too.
Every flow control valve is this.
Stupid two 45’s, 90 degree welded piping turns are this too. Pressure dropping turbulences zones.

Treat woodgas as fragile.
Treat woodgas gently.
Never intentionally as some do; make shear edge “mixing” zones.

It matters not whether the downstream soots are microscopic soots forced into visible amalgamations.
Or as I’ve come to believe actually turbulences energy CO to CO2 and free carbons reversion.
The soots will form and coat.

Welcome to the DOW GoranK.
You lift up the conversations already.

That material is spot on, I should go for the finest, 400mesh, not just hold finer soot out,
a finer mesh is a lot more “smooth” makes it easier for the “soot-cake” buildups to slip off and fall down, when they are too thick.
As for the intake there was only tiny amount of soot, thin like spray paint. Now after the filter cloth has sagged alot, I probably has to use a screwdriwer to scrape the soot out, only to make the butterfly flap visible.

Thank you Steve u.
Yes, woodgas is a perfect way to “get it visible” to see how and where it starts to buildup soot, with your own eyes.

You know what? That’s a Volvo as well :grin:
Here are a few more pics from the meetup.

That was interesting JO. I would have thought the van was loaded with a nuclear reactor. Did Volvo ever make anything smaller, like pick up trucks? I know they are big in Semi’s. Even build them in China.

Boy Tom; I agree about the nuclear reactor statement. Some of those looked like a plumbers night-mare. JO they will think you forgot to build something into yours— it is so simple and compact/contained. Was surprised to see a turbo=charged woodgas vehicle. I would have thought that at shut down the turbo would be so hot that with woodgas still up there and air that the system could blow up. Even with the turbo I bet yours is faster. JO what is that space ship on the van? It has two wires/hoses going up to it that appear to be “plugged into spark plugs” (not about woodgas but in the picture of the old Chevy touring car, what is that protruding off from the cowl?)

I’d like to find some plans on how they built this extension for their car. I know in the cover of the Gengas book they used the same type of trailer.

TomH, as far as I know Volvo never made a pickup, except terrain vehicles - for military use mostly.

TomC, at least the van was complicated like nothing I’ve ever seen.
I remember Ivar (meetup hoast) scratched his head when I explained I had only two containers - one with wood and one with hay and that’s it :smile:

Around the filler lid on top of the roof, there was a huge hollow flange or gutter. Since the hopper was inside the back doors of the van, this flange was all that was out in the open to form condensation.

Edit: I noticed I missed two paragraphs of your questionnaire, but realised they both have the same answer: - I don’t know :smile:

Cody, I think just two points hinge/bumper mounted and a pivot wheel in the back. Low speeds required :smile:

It seems like by percentage of population Sweden has more wood gas vehicles than anyone else. Doesn’t seem like the ones in the pictures have much fuel storage room so pretty limited range. As far as I remember, only Joni has been able to gather fuel off the side of the road.

I have seen videos where people still have signs up advertising they have gasifier wood at their places. World War II is over but some people do not forget and are ready if the fuel shortages ever come back.

TomH, from what I’ve heard Finland is no1 and Sweden no2. Represents the percentage of tinkerers I guess. But don’t forget the east. We know very little about countries like Russia and Ukraine. @Joni may have an idea about the percentage of woodgas vehicles.

Bob, I have to admit I’ve never seen anyone sell gasifier wood :smile: But the interest for gasification is up for sure. The majority of times I stop at a parking lot infront of a store, there’s someone coming up asking me questions. Not long ago a guy even tailed me around town into a parking lot. I had just dropped wife off for grocery shopping and it took me almost an hour to get back to pick her up :smile: She threatened to go by herself (on dino :tired_face:) next time, so I’ll better behave in the future :smile:

Of course there is gengas fuel to buy, you get a discount too.

Hello guys,
I really know how many people like to ride on firewood in the countries of the former USSR and I dare say that for Ukraine this percentage is 1:5000000, for Russia 1:30000000, for Belarus 1:4000000.:thinking:
In other words, almost everyone here knows about it, heard about it, but no one wants to do it. It is still fashionable to ride a “dino” here, if you ride on wood, then everyone laughs at you.:joy:

Haha, I had no idea. I wonder how much they get to sell :smile:

Haha! Yes, smiles are common but I get the feeling it’s starting to change. With fuel prices sky-rocketing more people are getting seriously interested.

I have feel that too, many thinks its a great statement against the ones that sets the prices for fuel. Somebody told me, THIS IS THE BEST IV’E SEEN IN A LONG TIME, I only wish i had the energy to build and drive one too. :grinning_face_with_smiling_eyes:

in my country, the price of fuel has been constant for about 10 years ($ 1 / 1 liter) and I do not observe any change in interest in driving on firewood.

That’s about in the middle of what we have now, depending on your region. A lot of it is road tax and I think the price in most of Europe is also super high tax rather than actual cost to process gasoline. Of course there is always the corporate gouge.
Current price for crude is about 85 US dollars a barrel. Many speculate it will hit $100 in the near future and some believe much higher. That will be good for Matt.
