A new generalized mechanism for photochemical smog has been developed. The mechanism is suitable for use in the Empirical Kinetics Modeling Approach (EKMA) to estimate the control of volatile organic compounds that is needed to achieve the National Ambient Air Quality Standard for ozone. The mechanism developed is called the CBM-X, and it is the fourth lumped-parameter mechanism to be designed in accordance with the carbon-bond reaction concept. The principal features that distinguish the CBM-X from previous carbon-bond mechanisms include separating formaldehyde from the other oxygenates, treating toluene separately from the other aromatics and including a more detailed, up-to-date representation of aromatic hydrocarbons chemistry. The CBM-X was tested by comparing the predictions obtained with the mechanism against smog chamber data of dilute auto exhaust/oxides of nitrogen mixtures obtained in the outdoor smog chamber facility operated by the University of North Carolina.
