The effect of EGR (Exhaust Gas Recirculation) on the emission of NOx , CO, and HC from two compact, low-emission burners sized for use in automotive Rankine-cycle engines was studied experimentally. One burner was a lean-primary design, and the other was a rich-primary design. Both had been developed to meet 1976 Federal Emission Standards for automobiles. It was shown that EGR resulted in significant reduction of NOx emission from both burners, with negligible effect upon emission of HC and CO. The effect of EGR was additive to the effect of excess air, staged air admission, and wall cooling.
