The Issues of the Air-Fuel Ratio in Exhaust Emissions Tests Carried out on a Chassis Dynamometer
Energies, 2021 Vehicle exhaust emission tests use exhaust sampling systems that dilute the exhaust gas with ambient air. The dilution factor DF is calculated assuming that the combustion is complete, and that the engine is operated at a stoichiometric air-fuel ratio ...

Emission Standards in Air Pollution [PDF]
American Journal of Public Health and the Nations Health, 1965 AN emission standard is a limit on the amount or concentration of a pollutant emitted from a source. The concentration of pollutant in the effluent may be stated subjectively in terms of its appearance to the eye or its odor, as determined by the nose; or objectively in terms of its weight or volume.
