Abstract

Systems for abatement of pollutants in an exhaust gas stream of an internal combustion engine including a hydrogen injection article configured to introduce hydrogen upstream of a catalytic article are effective for the abatement of carbon monoxide and/or hydrocarbons and/or nitrogen oxides. The introduction of hydrogen may be intermittent and/or during a cold-start period.
