Looking good Bob! I am wery interasted how your nozzle holds up.
Just a note. Your truck was idleing on petrol when you run those tests right? Petrol exhaust contains lots of water vapor in contrary to chargas exhaust wich is only composed of CO2 and N2. Your gas composition will change once you run a engine on pure chargas and run its exhaust back. The water will be gone.
I am actualy at a point here on my Mercedes where l have less mousture l wuld want, using just EGR. Damp or slightly moist towel sacks do a much better job of collevting dust thain completely dry ones. I have seen wery light dust in my pipes after the filter. If l stay with useing EGR only, l will have to add a final oil filter or uses tighter fabric, l eaven thod of squirting a occasional squirt of water in the gas before the filter, to wet the sack.
Ha, l remember Proffesor Baltazar! You are spot on JO had to look on wikipedia, had no idea its actualy a Yugoslavia cartoon.
We are all Balthazars on DOW usualy
