ABSTRACT:
The invention discloses a method of reducing the concentration of NO.sub.x in the exhaust streams of internal combustion ignitions wherein a selected producing agent is introduced into the combustion chamber of such an engine via the fuel and/or air feed stream introduced into the combustion chamber. Also disclosed is an apparatus for reducing the concentration of NO.sub.x in the exhaust streams of internal combustion engines having a piston-cylinder assembly having an air fuel mixture contained therein, a means for storing a selective reducing agent selected from the group consisting of ammonia, hydrazine and cyanuric acid and a means for introducing the reducing agent into the lean air/fuel mixture before combustion occurs such that upon combustion of the air/fuel mixture, the reducing agent decomposes to react with one or more products of combustion to produce an engine exhaust stream having a reduced concentration of NO.sub.x.
