In the past, one measure of realiability has been a carbon balance between the fuel used and the C, CO, hydrocarbons, and CO2 emitted which requires that a F/A ratio be known accurately and that the analyzed sample be representative. In addition to this carbon balance, we have considered the relationships between the concentrations of the several component species. For example, the plot of volume percent of CO2 versus the volume percent of O2, both property corrected to complete combustion, is a straight line. In addition, smooth functional relationships exist between other exhaust gas constituents as well, although the form is not a simply derivable linear relationship like that for 02-CO2. We have found it useful to employ the following correlations: CO2 vs. log NOx log CO vs. log THC, log CO vs. CO2 and log THC vs. CO2. These relationships serve to indicate the probability of reliable data and point out sampling problems and instrument problems such as drift.
