| Resumen: | This SAE Recommended Practice establishes uniform laboratory techniques for the continuous and bag-sample measurement of various constituents in the exhaust gas of the gasoline engines installed in passenger cars and light-duty trucks. The report concentrates on the measurement of the following components in exhaust gas: hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO
2
), oxygen (O
2
), and nitrogen oxides (NO
x
). NO
x
is the sum of nitric oxide (NO) and nitrogen dioxide (NO
2
). Historical techniques still used for some purposes are included in the Appendices. A complete procedure for testing vehicles may be found in SAE Recommended Practice J1094, Constant Volume Sampler System for Exhaust Emissions Measurement.
This recommended practice includes the following sections:
(1)
Introduction
(2)
Definitions and Terminology
(3)
