摘要: A system of purifying exhaust gas may include an engine including injector, a lean NOx trap (LNT) adapted to absorb nitrogen oxide (NOx) contained in the at air/fuel ratio, release absorbed rich and reduce or released oxide, dosing module inject reducing agent into gas, selective catalytic reduction catalyst on diesel particulate filter (SDPF) matter using injected through module, controller performing denitrification (DeNOx) LNT when temperature be lower than transient temperature, SDPF higher equal temperature.
