I have a Chinese JXQ-10 stratified downdraft system (no nozzles) which uses water for cooling and filtration. So, yes I am a weirdo. Anyway---- I ran my first drizzling test and learned a lot, but didn’t make a lot of good burnable gas this time. No fault of the drizzling idea, just multiple cockpit errors, etc…
here’s why I am making this post (a copy of one part of a much longer one I made on the Yahoo group):
One VERY interesting thing was that this was the first time I ran the genset on woodgas with the narrow band oxygen sensor in place and recording. When I run it on gasoline, the voltage is very steady at about 0.8 volts, even with large changes in load. But, during the few times that I got the engine running on woodgas, the O2 sensor read VERY low, at about 0.1 volts. That would be quite LEAN, wouldn’t it? I don’t know why this happens, but it is VERY repeatable. I’d like to hear the experiences of others in this regard.
This VERY lean reading persisted even as I adjusted my woodgas/air valves. During this run I collected data on all that was going on, but just showing a graph without being there to interpret it wouldn’t be very useful to most. If you MUST see what it looked like, you can PM me.
I know some of you are using an O2 sensor and that, hopefully some of them are narrow band.
And I don’t know if wide band sensors would read differently IN THIS CASE.
Someplace on this site there’s a video of Wayne starting up one of his trucks and “tuning” the mixture using the analog dashboard meter, and he did tune for “just right”, but that was probably a wide band sensor.
Anyway, I just don’t know if it’s just my system or what—
