Ingenious and workable ways to reduce pollutants in internal-combustion engine exhaust have come from the Sibley School of Mechanical and Aerospace Engineering. Modifications have been developed that would enable the automobile manufacturing industry to meet emission standards without abandoning current technology. Control of nitrogen oxides is achieved by operating on the rich and then the lean part of the pollution curve, much as in the stratified charge scheme. The Cornell "flaming muffler" requires modification of one cylinder and its connections, and the attachment of the external combustion chamber with its heat- exchange unit. Studing the mechanism of the reduction of nitrogen oxides has also resulted in the development of the Cornell spark plug which reduces emissions of nitrogen oxides to a currently acceptable level.
