Exhaust gas recirculation was found to be a promising approach to NO emission control when used in conjunction with either engine modifications or manifold air injection to control hydrocarbons and carbon monoxide. NO reductions of about 60% were achieved with minimal debits in fuel consumption, driveability and CO and hydrocarbon emissions. Long-term effects remain to be established.
