DIY emissions analysis
As a techie with an almost Aspergerian desire for measurement, I'd love to be able to do my own emissions measurements and logging, especially on-the-fly. To buy such a system I think is about $6K-- that's what a local tech school paid for theirs. Many of us semi-retired Dads don't have that kind of money in petty cash on a regular basis, so I thought that I would try to put together my own system (at least until Publisher's Clearinghouse shows up at my door with that big, big big check).
Apparently DIY emissions analysis is a very rare topic, so rare that I can't find anything.
"Who will help me plant this wheat?" said the little red rooster.
Oxygen sensors aren't expensive and ought to be straightforward enough to interpret the output.
For diesels, it seems to me that an opacity meter ought to be easy enough to rig-- a chamber with a light and a light meter. I hear green light is favored.
As for NOx, CO, CO2 and HC, I have no clue as of yet-- have yet to read the technical articles.
I'm not looking for EPA or California Air Quality Board level tolerances, although I wouldn't be surprised if I could get them. Does anyone else think that having these measuring abilities would help in ecomodding research?
