TL;DR: In this article, an exhaust emission control system of an internal combustion engine capable of post injection is described, which enables an efficient rise in the exhaust temperature while inhibiting deterioration of the drivability due to a rapid change in torque.

TL;DR: In this paper, a NOx catalyst for selectively reducing NOx in exhaust gas by adsorbing ammonia is provided at an exhaust system of an engine, ammonia or urea water is supplied to the nox catalyst by reducing agent supplying means, a consumption amount of ammonia adsorbed to the Nox catalyst is derived by consumption amount deriving means based on an exhaust amount of NOx exhausted from the engine detected or estimated by NOx exhaust amount deraining means and an actual NOx cleaning rate by the NOx catalytic converter derived by actual NOX cleaning rate der

TL;DR: In this paper, an NOx catalyst for selectively reducing NOx in exhaust gas by adsorbing ammonia is provided at an exhaust system of an engine, ammonia or urea water is supplied to the NOx catalytic unit by reducing agent supplying means 29, a consumption amount of ammonia adsorbed to the Nox catalyst is derived by consumption amount deriving means 43 based on an exhaust amount of NOx exhausted from the engine detected or estimated by NOx exhaust amount deraining means 41, and an actual NOx cleaning rate by the NoX catalyst derived by actual NO

TL;DR: In this article, an Abgasreinigungssystem fur einen Verbrennungsmotor, der mit eine Oxidationsfahigkeit mittels Edelmetall realisiert, ist eine Kraftstoffzufuhreinrichtung zum Zufuhren von Kraftstoffs an die Abgas reinisert.

TL;DR: In this article, a common rail system is used to inject fuel for post injection into a cylinder in an expansion stroke after main injection, and a control unit ECU of the exhaust emission control device practically controls the fuel injection and sets a target injection quantity and a target fuel injection timing of the post injection.
