although I sealed the air line as well as possible
I can not adjust the air / gas ratio with my butterfly valve cituated upstream of
flowmeter.
Do you believe that the hose that comes from the resonator and between the air filter and the flowmeter could de-adjust the valve
Thierry
Thierry,
Any hose bypassing your valve will offset the air-mix. Try see to that your valve has the same conditions as your flowmeter.
Has anyone ever tried this kind of pressure sensor to measure the differential pressure of gas and air at the mixer?
the sensitivity of this kind of probe is it accurate enough to manually adjust the air restriction valve?

Hi
I am looking for information to build a safety filter to complete the gasification plant on my truck. I read that wire cloth filters were recommended. Does anyone have information on this subject?
Thierry

Thierry,
Looks like a beautiful solution to me, just make it fairly easy to inspect, and well-sealed from outside air. 
Most guys just trust their regular paper air filter. The metal screen safety filters that I have read about recommend 25 micron or 400 mesh. I think about 100 square inches would be adequate, but have a replacement filter ready since cleaning the fine filter screen can take some time and effort.
thanks for the information Bruce

Hello everyone
I built this automixer for my truck.
I think itās different from other automixers.
the transfer of the movement does this by a hinge in place of the longitudinal displacement of an axis
this design facilitates sealing and minimizes mechanical losses caused by friction
What do you think?
Thierry
Sounds interestingā¦
The video link doesnāt work.
Try again, I fixed it!
Excellent solution!
That should make things a lot easier.
Hi Thierry,
Thanks for sharing the idea and video, but I donāt understand what Iām looking at. How about a sketch? I can imagine a hinge fastened to the diaphragm, but donāt understand how you are sealing the output rod.
Excuse me time for the answer, I am very busy at this time of the year
Bruse here is what I use to seal
Another advantage of this automixer design is that it can also work horizontally
Thank you for taking the time to answer. Very Clever.
Hello everyone
I would like to replace my big 5 "cyclone with two small cyclones in parallel.
Or can I find the information to size cyclones of equivalent efficiency?
Thank , Thierry
I think l used 2 4" cyclones on my mb, worked well. Oh, that was paralell!
Dyson uses a huge array of smaller cyclones in their vacuums. They take their engineering pretty seriously so I donāt think the cyclone arrangement is an accident.
The motivation could be more compact packaging but I think it has more to do with smaller cyclones having higher accelerations to help with separation efficiency. Now that I think about itā¦ Iām sure there is plenty of academic literature on the subject.
Sounds interesting. Hoping to see more info about Dyson projects.
I think the Dyson design is efficient enough to remove smoke from air, but the bottom line is it does so with a major consumption of power. In a gasifier system that will amount to a big pressure drop, which will rob significantly from engine power. With a super charger that could be overcome.
But, in engineering thereās such a thing as ātoo goodā, and I suspect this is one example. Max has described a sound system utilizing reheating and a final paper filter to minimize pressure drops.
Steve has theorized that turbulence causes CO to revert to carbon black. A Dyson would certainly put that to the testā¦
