I started a thread over in "INSTRUMENTATION" where I wrote:
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?
++++++++++++++
Obviously the emissions analysis box-makers aren't going to help me avoid paying them six thousand dollars.... maybe some o' the folks at professional testing labs might have some pointers-- or the bright young people at our institutions of higher learning might have blazed a trail for us already.
E-mails are in order. Maybe even personal phone calls.
