The status of the I.I.E.C. (inter-industry emission control) programme for control of automotive emissions and the technological achievements in some specific tasks are described. Catalysts and converter systems for the reduction of carbon monoxide, hydrocarbons, and oxides of nitrogen have been developed, some further improvements in activity and stability will be required to meet the latest proposed U.S. emission standards. A fundamental predictive mathematical model has been developed for carbon monoxide and hydrocarbon converters, and some examples of its predictive capabilities are presented. The use of thermal reactors for the control of carbon monoxide and hydrocarbons and exhaust gas recirculation for oxides of nitrogen reduction is also discussed. The performance of four concept emission control systems developed in the I.I.E.C. programme is given for actual vehicle operations. /AUTHOR/
