摘要： An operating method of an exhaust gas aftertreatment system including at least a particulate filter for retaining soot from the exhaust gas of an engine and a deNOx catalytic converter for reducing nitrogen oxide in the exhaust gas of the engine is provided. Operation regimes of the particulate filter and of the deNOx catalytic converter are synchronized with respect to each other for performing regeneration of the particulate filter while the catalytic converter provides a nitrogen oxide conversion efficiency above a predetermined limit.

摘要： It is an object of the present invention to make it possible to burn and remove particulate matter without generating runaway even if the particulate matter is excessively accumulated at the time of regeneration of an exhaust gas purification device (202). A common rail engine (201) and the exhaust gas purification device (202) placed in an exhaust gas path of the engine (201) are provided. A plurality of regeneration controls for burning and removing the particulate matter accumulated in the exhaust gas purification device (202) can be executed. The plurality of regeneration controls include at least non-operation regeneration control for rising exhaust gas temperature by combining post injection (E) and predetermined high speed rotation speed, and recovery regeneration control which can be executed when the non-operation regeneration control fails. In the non-operation regeneration control and the recovery regeneration control, the engine (201) is driven exclusively for burning and removing the particulate matter. The recovery regeneration control is carried out at exhaust gas temperature lower than that of the non-operation regeneration control while taking time longer than that of the non-operation regeneration control.
