Abstract

A selective catalytic reduction system for reducing nitric oxides emission levels from a compression ignition engine includes a first reductant injector located upstream a first catalyst including a selective catalytic reduction coating. A second reductant injector is located downstream the first catalyst; and a second catalyst is placed downstream the second reductant injector and includes a selective catalytic reduction coating.
