Control system for supplying air and exhaust gases to an internal combustion engine and for discharging the exhaust gases generated by the internal combustion engine from the internal combustion engine

摘要

The present invention relates to a control system for supplying air and exhaust gases to an internal combustion engine (12) and for discharging the exhaust gases generated by the internal combustion engine (12) away from the internal combustion engine (12), comprising a supply duct (14) for supplying the air and Exhaust gases to the internal combustion engine (12), a discharge duct (38) for discharging the exhaust gases generated by the internal combustion engine (12) from the internal combustion engine (12), in which one or more exhaust gas aftertreatment units (40) are arranged for aftertreating the exhaust gases, one im Supply duct (14) arranged heating device (32) for preheating the air and / or the exhaust gases that are fed to the internal combustion engine (12) is provided. The duration of the heating process and / or the heating power output by the heating device (32) is controlled as a function of a variable that approximately represents the state of aging of the at least one exhaust gas treatment unit (40). The invention also relates to an internal combustion engine (12) with such a control system (10), a vehicle with an internal combustion engine (12) according to the invention and a method for operating the control system (10) according to the invention.
