An emissions system for reducing nitrogen oxides in engine exhaust includes an emissions catalyst having an inlet adapted to receive an exhaust from the engine. A fuel tank is adapted to provide fuel for combustion within the engine. A first injector is operable to inject fuel into the exhaust upstream of the catalyst. A second injector is operable to inject supplemental reductant from a supplemental reductant tank into the exhaust upstream of the catalyst. A controller is operable to control the first and second injectors and vary the supply of fuel and supplemental reductant into the exhaust to reduce nitrogen oxides within the exhaust.
