Phone picked up my voice a little too well, might want to turn the volume down a tad.

Those are the reports we like to see! Great.
I cant tell if the glow is from the nozzles or is the whole flute glowing?
55mph is what l wuld realisticly expect from this truck and engine. I bet you are pleased!

Thank you for the ride, fun to ride with you.

I couldn’t tell either. I’ll have to check the flute for damage to find out.

Checked my odometer, I went about 22 miles in various grades of hills. Charcoal was right up to the gas exit level and now it’s right here.
Here’s the best picture of the inside of the nozzle that I could muster up.
And the sack filter seems to have worked really well it’s covered in very fine dust.
I’m very pleased with how well covered the bag is, I was worried the bag would conform to the size of the inner pipe and only get partially covered. Every time I moved the bag it was shaking dust off. Inside of the filter box is hard to see without waiting for the dust to settle but that tells me it’s getting down to the very fine stuff.

Just checked the Mazda to see if she will idle fine on gasoline, everything seems to be okay now.

Looks like I’m in the 2 miles per pound range.
Used up 6.5 gallons of charcoal, which according to my 5 gals to 9lbs figure, or 19 Liters to 4 Kilograms, for my charcoal is 11.7 lbs. From the roughly 22 miles I drove. Not bad!
Correct my math but that would be 7.1km/kg?

Also i think I could stand to use a little bit more water in my drip. Right now I’m doing one drip per second so I’ll try to up it to 2D/s
I will expect a bit over 1kg charcoal equivalent to 1l petrol. Then just punch in whatever the cars consumption of petrol is.
Theoreticly one Kg of char can reduce close to one Kg of water in a gasifier, but there is no need for that much. You do the math for your ideal amount but l can tell you that its more thain 1 drop/s. Problem thugh is at idle and full power the need of water is different… Its why l dont like drips.

I’ve been thinking of copying Bruces mister idea but tying the voltage to the alternator to give it a stronger flow while under acceleration. I would need a pretty sturdy pump to withstand the higher voltages though.
Also on petrol I get roughly 8.5km/L when at cruising speed of 55 in Overdrive.
I always wanted to try the Maxs idea for a carbourator fed water mist. Sounds perfect for what we need but as l know noone yet tryed it.

All I would need to do is build a venturi right? I could maybe make a venturi from the other end of the flute where I put a coupler in.
Just copy a Briggs and Stratton style tank carburetor really. I’m just not sure what jet size I would use.

I thought you use 20% water to wet your charcoal. That sounds easy to me.

Yes, with a downdraft. Updrafts need as dry charcoal as possible.

That’s why Matt’s water system makes sense to me. The pull of the engine determines how much water is injected. Excess water at idle or low RPM would just drain away. At least that how I see it.

Matt’s system works great for his form factor, but I don’t know how I would engineer it for a flute nozzle.
I tried the carb on the air feed a year or so back , a few problems with water and carb’s not mixing so well due to corrosion , as for a flute nozzle it will work the same way as any other type of nozzle as air is drawn in it will suck up some of the fluid , the only reason i stopped using mine was when i tried this i was using a 1 inch nozzle and for my generator running a GX390 engine it did not have the velocity needed to draw up from below as mine is fed from below with a vertical nozzle .
The generator runs the exact same carb on the generator and so i put a smaller main jet in so as not to flood the system with water .

That’s why I think I would just need to make my own venturi to screw into the pipe coupling.
But Matt’s system uses like a boiler tube almost. Unless I’m dead wrong. I could maybe try to replicate his water carburetion by using one of my flute ends to suck in the water. I think his system also still relies on setting a drip.
@Matt does your internal tube still close off near the end of the nozzle?

Ive scrapped that plan it didnt work. This is what I do now
The holes are in an array and the entering air creates a low pressure on the water drip feed tube to keep flow consistent. So no more need to pressurize the tank or use a pump. Then the air is focus to the center of the nozzle breaking up the water and forming an even mist that coats the jet evenly. The mist evaps instantly.
Its so simple and works quite well i more than likely will never change this.
For shut down I dont worry about it. I just shut the genny off and close off air mixer. it shuts down just fine with no smoke.
