Measurement of the Atmospheric Reactivity of Emissions from Gasoline andAlternative-Fueled Vehicles: Assessment of Available Methodologies. Part 1. Indoor Smog Chamber Study of Reactivity. Final Report for the First Year, January 1-December 31, 1993

摘要

A set of multiple indoor smog chambers were used to measure the increase in smogformation (smog = NO oxidation + O3 formation) from a series of individual test volatile organic compounds (VOC's), as well as carbon monoxide (CO), when they were added to a standard urban mixture and irradiated for 10-12 hours with a solar simulator. The chambers and the mixtures were designed to simulate the Carter incremental reactivity concept that is being used in California. The test compounds covered a wide range of mechanistic uncertainties and predicted reactivities (reactivity is the increase in smog divided by the amount of test compound added). Also, the chambers were used to test the recently developed Integrated Empirical Rate (IER) Model which predicts that the smog formation of a mixture is constant and independent of NOx in the so-called light-limited regime.
