To this end, provision is made for an nox selective reduction catalyst arranged in an exhaust passage of the internal combustion engine to reduce nox by means of a reducing agent supplied thereto, a supply device to supply urea water as the reducing agent from an upstream side of the nox selective reduction catalyst, a pm sensor to detect an amount of particulate matter in an exhaust gas at the downstream side of the nox selective reduction catalyst, and a control unit to make an amount of production of intermediate products from the urea water supplied from the supply device to ammonia smaller when an amount of particulate matter is detected by the pm sensor than when not detected..
|System, method, and apparatus for controlling an aftertreatment system having a particulate filter and a rich nox conversion device|
A system includes an internal combustion ignition engine with an exhaust gas flow, a particulate filter in the exhaust gas flow, a nox reduction catalyst in the exhaust gas flow downstream of the particulate filter, a first oxygen sensor coupled to the exhaust gas flow downstream of the nox reduction catalyst, and a second oxygen sensor coupled to the exhaust gas flow between the particulate filter and the nox reduction catalyst. A controller includes an exhaust conditions module that interprets a first oxygen signal from the first oxygen sensor and a second oxygen signal from the second oxygen sensor and a combustion control module that commands a high engine-out air-fuel ratio when the first oxygen signal indicates a low oxygen content and commands a low engine-out air-fuel ratio when the first oxygen signal indicates a high oxygen content..
