Now l used the 2 wet cyclones. They worked wery well with woodgas, expeling moisture and soot out from the gas. I left them in when testing the chargas sistem, but now its time for them to go.They cant work properly with dry chargas.
The jetronic machanisms were clean when l started. Just oily. They got sooty black when l started to DOW.
But its not just soot, its allso other corrosive compounds l was afraid of.
Its not they got abnormaly dirthy, just normal woodgas dirthy. No problem in most sistens, but (potentialy) problematic for this delicate fuel injestion mechanism.
What you say makes sence.
The new filtration. First, l will try to fit on a cyclone. It that isnt possible, the dusty gas will go trugh the cooler to the engine compartment, in a sack filter similar to the one l had in my Seat. Only change will be the new filter will have more smaller sacks with nozzles inside, thugh wich a blast of pressurised air will be blasted in dayly to shake the dust off. Collected at the bottom and auguered out. We have a identical sistem where l work, only much, MUCH bigger. Works 24/7 for years with no problem.
After that, l pulled the gas trugh the original paper filter on my Seat. Thats not possible here, so l might make a oil final filter. Will see.
I spent a lot of time in the workshop lately, makeing the new tb system. The problem is connecting both throtle bodys to work independantly and together if neaded (hybriding) with just one gas pedal. But l think l got it now and l an quite pleased with how it all looks like.
