Anyone here regularly use an exhaust gas analyzer?
What are you needing? The 4 gas, or 5 gas would be used more often in areas requiring emissions testing (we dont).Anyone here regularly use an exhaust gas analyzer?
With my two finger hunt and peck typing, I dont think you have a month to wait on an explanation. Look up hydrocarbons, oxides of nitrogen (NOX), co2, oxygen, and emissions testing with the 4 or 5 gas analyzers.I have a 5 gas analyzer.
I am wondering if you or anyone here has experience interperating results and putting them into the context of a given vehicle/application to then be able to tell exactly how the motor is running.
I am not talking about pass/fail emissions testing, but rather diagnosis and analysis.
Understand this is a guess, from my limited experience with emissions analysis. I would think the hydrocarbons would go down, NOX lower because ethanol doesn't burn as hot, but the bump in timing would raise it again. Not sure about the co2 and oxygen.I understand the basic theory, plus I have a book that has alot of info on the subject - so I am not looking for a start to finish explanation.
I was just wondering if anyone does regular work with an analyzer because I have a few specific questions about it.
1) Exactly what effect do the ethanol blended fuels (E10 in particular) have on the emissions readings?
2) Exactly what effect does ignition timing have on the emissions readings? If, for example, you go from 10* BTDC to 15* BTDC (spout removed) what would you expect (if anything) to change?
