NOX is produced by the high temperatures in the cylinders during combustion. to reduce NOX; engines were slightly retarded in timing as well as having some exhaust gas introduced into the intake manifold. The latter is the function of the EGR valve. All of which is now controlled by your onboard computer or PCM (powder train control module)
