Tom, if you’re refering to the drawing above - that’s @Tone 's gasifier He may be able to give a better answer.

JO Trying to bring up the picture that I am/was talking about. Nope can’t remember how to post a picture. So, go up to the post where I asked the question and it shows who I was replying to (j* JO_Olsoson), Click on the J and it will take you back to the post with the picture. TomC

Oh sorry, that’s a 5 ga bucket. It’s my hayfilter.
The gray/white/orange 4 in plastic tubing below is the condensation vessel (rear tank). It sits down into the compartment behind the wheel well in the trunk.

Went into town to buy some brake related stuff for the Mazda. Pretty cold until today. Suddenly melting temps. Just in case there’s another cold snap I try to remeber to pee right before I reach home again.
Read on Wayne’s 95 Dakota yesterday how he arranged his remote pee control. I still have to get out of the car.

I often wonder what people think when driving past and see a jet black puddle and a dirty brownish puddle next to it. Did bigfoot have taco bell?

We all got in trouble at Argos for doing this on the country road. Now we have a special barrel to put it in. Indiana is not Sasquatch country we could not blame it on him.

I remember last summer when Jakob North did his historical drive across the USA up through the Northwest and back across the northern part of the USA. We stopped on top of Snoqualmie Pass and his truck did a big Big Foot pee , I was surprised that it left very little mark in the gravel on the side of the I-90 freeway. Non polluting organic weed killer.
Better then what the State spreads on our road sides to control the weeds. JO you are doing a good service for weed control. SWEM.

Duh. Took me a minute to realize you guys weren’t talking about a funnel in front of the seat with a hose through the floor board.

Haha! Tom, as far as know not even Wayne has integrated that kind of refinement into his woodburner vehicles

I came to think of you JO, when I try to find out why my vacuum meter hits the bottom. Did the Volvo get better when you increased the restriction?

Jan, I didn’t increase it. I have the same 4" restriction. I raised it 2.5", but I can’t tell no difference in behaviour. The charbed often tightens more than I like and hesitation sympthomes are the same.
At lightup I rattle the grate with the poker and I’m OK for half a hopper or so. Half an hour into the burn I’m starting to see higher vacuum ratios again.
I haven’t really had the time to do anything about it, but I have a theory.
Wayne uses finger size nozzles. I have only 8mm ones. It would take a newborn’s finger to fit into them. I belive the air velocity is high enough to penetrate and shatter the charcoal into fines in a very early stage. Digging down to raise the restriction confirmed my theory. There vere lots of fines in the charbed, starting already right below nozzle level.
Also, this may contribute to the hesitation sympthomes as well. Big lazy nozzles will probably pour the air down the walls of the firetube at idle, making oxygen last down closer to the restriction (more heat down low) and leaving the center of the charbed unaffected. With tighter nozzles and the already shattered charcoal, with lots of surface area, the oxygen will be consumed at that level and the restriction kept cool.
We’re just about to light up for a 160 km trip today. BBB.

Yes JO, this is very true. This is why the size and hardness and how the wood is possessed is important according to each gasifer’s design and type that is built.
Your gasifer might not run on the size of wood that I prosses and vise versa.
So the nozzles how many and size of the nozzles opening play a big part in the gasifer’s velocity in the upper part. Also the restriction’s opening where it is placed, closer or further from the nozzles. And must not forget the opening diameter where all the charcoal/ashes, gases will go through at very high level of heat and velocities. This all creates a high vaccum zone and must clear or purging it self of the ashes and charcoal that is burning up.
When I push down on my accelerator pedal or let up on my accelerator pedal this will cause this kind of breathing action needed. It is a high to low vaccum action. To me when I have a hesitations at long stop idle it can not be air to gas ratio, because my auto mixer is keeping a 1:1. It must be weak gases.
Now if I have hesitations at a stop and go. I would think I have good gases, because it takes a while for weak gases to make it up to the mixing box. If I look at my vaccum gage and see high vaccum then I know I have a tight charcoal bed that is causing the hesitations.
I am sure you know all this all ready JO, but I want you to know that these are things that I too experience with my gasifer at times on a much bigger unit with larger liter engine.
Always trying to make my gasifer run better. Bob

Bob, at some point I’ll do three things. Install a grate shaker, increase the restriction diameter and install bigger nozzles. One at the time.
The Volvo does run on wood as is though. 100 miles on wood today. Wife made this video when we climbed the mountain up to m-in-law’s. A lot more snow up there. No point just yet to follow your lead and try melt the last pieces of ice

Hi JO, i maybe missed reading it somewhere, but i wonder if you have the Volvo inspected with woodgas?
4 Likes
Göran, the Mazda truck is approved with gasifier and all, but not the Volvo. I haven’t bothered trying yet and I’m not even sure it’s possible.
I’ve been checked by the police once and they didn’t seem to mind. I think worst case senario I’ll be ordered to go do a registration inspection.

JO, your wife makes great videos. Thank for the winter wonderland ride with you both, and the dogs I suppose.
We seem to have 4 equally divided seasons here. Just trying rush it and move it into spring. I need to keep saying “Be patient Bobby it will come.”
And then when it gets here summer follows. Then I will saying it is way to hot. Lol. You just gota love it and go with the seasons. That least I can work now outside with out a coat, gloves, and a hat on trying to stay warm. More 50°f weather nice.

Yes JO on the Volo gasifier one change at a time. You will soon have it tuned up perfectly for all your driving conditions.

Thanks, JO, yes it’s probably the way to go with newer cars, altought i’ve heard some promising rumors that it could be possible
because of “twin fuel” regulations like gasoline/ ethanol, law says you can inspect/test it at one of the fuels, that is the “number one” fuel.

That would be great news if they ever start inspection on the wood gas vehicles here in the USA. Opps I should not say that lets leave things the way they are now. On inspection of vehicles.

Göran, mine is a 95a and inspected, Gengas Werner has clearly got through a dispensation that allows newer cars to be inspected as well.
