A description is given of an integrated emission control system for spark ignition automotive engines using neither catalytic combustion nor afterburning. The system includes lean carburetion, secondary air injection, exhaust gas recirculation, and retarded timing. Emissions data are given for CO and hydrocarbon emissions, and the tradeoff between exhaust gas recirculation (NOx control and driveability is discussed. (PMA)
