J254_201106 - Instrumentation and Techniques for Exhaust Gas Emissions Measurement

Details
Document Number: J254_201106
Revision Number:
Title
Instrumentation and Techniques for Exhaust Gas Emissions Measurement
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). A complete procedure for testing vehicles may be found in SAE J1094.
