Thanks for the thumbs up guys!
Ok, l got half the cooler done today, half tomorow.
I was thinkig alot about filtration.
Hot filters are great. For a metal intake manifold. They keep the coolers clean but soot still breaks free trugh them, causeing buildups in intake manifold. If you can burn it out, great. If you cant, well, it realy is a pain in the sitting organ.
So, l decided to go somewhere else. Good old hayfilter, but combined with a bubbler (some Youtube videos, includeing @ALLIWANT2DOISFPV showing his sistem, made big interast to me) and a venturi scrubber.
It may look complicated, but actualy is very simple and cheap.
Gas first flows trugh the venturi ejector, where it mixes wirh water droplets. Pass upstream, then down trugh ss pads, where soot can be collected with water droplets. Both water and gas pass a water reseroar, gas bubbles up towards the top. Water gets reused and gas filters its self in a conventional hayfilter.
After this, the gas shuld be clean enough. If not, l have space for one more, a towel filter, like l used in my Seat.
l got the barrel today, 30l fits great in the alubox. Allso gives some buffer in terms of gas quality. Not as much as most of you guys use, but a lot more thain zero wich l had before.
At low throttle, there likely wuldnt be much of the venturi effect in the ejector. Doesent matter! The filter shuld still be wet enough, allso at idle there is a lot less dust sucked from the gasifier. Plus, the bubbler shuld catch soot no matter the gas consumption.
Question to you guys. What do you think the venturi throat diameter shuld be without dragging the gas stream too much?
l was thinking thinking to start with 1" or 25mm. Maybee a bit smaller.
