MEASUREMENT OF CARBON DIOXIDE, CARBON MONOXIDE, AND OXIDES OF NITROGEN IN DIESEL EXHAUST J177_197006

The method presented applies to the analysis of the indicated constituents in diesel engine exhaust, or exhaust of vehicles using diesel engines, when operating at steady-state conditions. The measurements of carbon monoxide, carbon dioxide, and nitric oxide are based on continuous sampling and analysis by nondispersive infrared methods.

A supplementary batch sampling, wet chemistry method is described for analysis of the oxides of nitrogen.
