J254_201106: Instrumentation and Techniques for Exhaust Gas Emissions Measurement

Features

Issuing Committee: SAE IC Powertrain Steering Committee

Scope

Content

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 (NO_x). NO_x is the sum of nitric oxide (NO) and nitrogen dioxide (NO₂). A complete procedure for testing vehicles may be found in SAE J1094.
