Abstract

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) Emissions Sampling Systems (4) Emissions Analyzers (5) Data Analysis and Reduction (6) Associated Test Equipment (7) Test Procedures (8) Appendices A , B , and C
