Scope

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 (CO2)@ oxygen (O2)@ and nitrogen oxides (NOx). NOx is the sum of nitric oxide (NO) and nitrogen dioxide (NO2). 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) Emissions Sampling Systems (4) Emissions Analyzers (5) Data Analysis and Reduction (6) Associated Test Equipment (7) Test Procedures (8) Appendices A@ B@ and C
