No, but it is very difficult to both give full air while I turn on the pump, very easy for it to stop.
I have a pwm, but do not know if the car needs full pressure to work.
And my pwm probably needs to control a relay to work, four-wire.

Yes, but it is just a headlight switch rheostat and I use it mainly as an on/off switch

Good morning Jan .
It should be easy to drive on gasoline and at the same time began to draw from your gasifier . As the fuel mix to the motor gets rich the truck computer should lean out the gasoline to a point where you are driving hybrid .

It does not seem like my car works that way, I usually start on petrol, and after a few minutes the car dies when the gas is good.
Likewise, if I turn on the gas pump when I drive, the car dies immediately, if I do not give it 100% air.

Do you have a shut off valve on the woodgas pipe going to the motor that can be operated from the cab ?
If so it may need to be restricted to avoid fuel being to rich entering the motor .

I probably have to explain a little better. I usually start the car on petrol, and slowly reduce the air, after a few minutes the car starts to get too much gas and I turn off the petrol pump. After a while I have to give more air for the car to run well on gas.
Should I then drive on petrol when I drive on gas, I must give full air otherwise the car dies
I have not tried to reduce the gas to the engine instead, but is it better than increasing the air?

Open up the air first. If that’s not enough, reduce woodgas flow. If both valves are restricted you risk pulling too much vacuum on them.

What happens when I light the unit and is ready to go, when I turn off the fan, it will be a setback as it smokes across the platform from the air intake?

Wondering if I’m too old for this?
I started the fan this morning but did not put it on the pipe, but lit the boiler with LPG, and there was an explosion, so coal and wood spread over the ground in front of the garage, the entire roof and the bed of the car.
Got to go on petrol today.

Jan, wow. Everybody OK?
That is not supposed to happen.

Woodgas power! A/F-ratio just right 
Happens 1 of a 1,000 times if you’re not following your daily routine.
Is that the restriction blown away and landed on top of the wood? Must have been a powerful puff

It went well thanks to the lighter having so far tubes (weed burner).
Yes, it is restriction that is on top of the wood that remained, had wood all the way down to the grate, when I cleaned it last night.

Could have been me… I do the same typical things… Glad no one got hurt. Big blast it was!

Not sure if you meant this, you need a bed of charcoal from grate to raw wood.

It was because raw wood came down all the way to the grate that I had to clean all the way down, I had coal left since the last cleaning that I had in after cleaning.
It was strange this morning, the car went very well, was much stronger than usual.
I had a leak on the outside restriction that I welded together, can it affect the car?

Tried yesterday to make a cone of more than 60 degrees to the unit yesterday, to avoid hanging.
Tested today and it turned out worse than usual, what is it that makes the wood hang so easily?

Hi Jan, this a easy one to answer. Sticky Wood Tar in the hopper. I have had wood stuck on the straight vertical walls of my hopper when it cooled down. So here is the secret if my hopper gets to 200 degrees F. / 93.3 Celsius the wood seems to slide into the fire tube. Also try cutting your wood a little smaller might help if you can. I have a 12" opening where yours is smaller. One other thing you might try is to put a light coat of oil on your new cone. Used motor oil will work and see if this will help.

Jan, in the second picture it looks like the wood is locking up against each other like what happens in wood bridging over the fire tube. Try making your pieces smaller. Maybe half the size.

Hi, Jan!

Untested idea for hanging:
Make a “staircase” 1/3 perphery wide.
Bend the steps horizontally along the silo wall.
Height from step to step: one hand width. (~4")
Step material: 0,5 --1 X 3" horizontally flat.
The “poles” 2X2".
The principal of action: The ladder will hold up a part of the clogging “piston”, forcing it to continuosly brake into peaces when it attempts to avalange as a whole peace.

I think I understand what you mean Max, but I’m hesitant about the result.
I would probably need a reverse cone to be sure.
The problem is probably that the wood that I have run through my woodcut was a bit dry, which causes the wood to break into smaller pieces.
Joni had an idea to raise the nozzles, but I do not understand how this would work.
I tried again yesterday with the cone, could go about 5-6 miles, then the temperature rose sharply in the wood container and the car stopped, when I would then go home it only went on 4-5 cylinders for a while, not good.
This is what it looked like last night when I got home.
