Among the objectives of this research were evaluation of a variety of designs in chemiluminescence analyzers used in heavy-duty testing; determination of the effects of sample line temperature and sample flow rates on emission values evaluation of an interference-free dual detector NDIR NOX analyzer system; comparison of emission results attained in parallel vs, series flow configuration, of five vs. ten-minute modes in test cycles and of emission results attained with Teflon vs. stainless steel sampling lines. Comparative findings involving instrument equivalency, composite cycles and modal differences were indeterminate. A major problem involving the NO/NOX crossover was uncovered. Until it is resolved there remains a question regarding the proper utilization of NO//2 to NO converters. The best performance in the study was demonstrated by the interference free NDIR system.
