Control system of an exhaust gas treating device of an internal combustion engine

摘要

The control system has a dosing system for introducing a reduction medium into the engine exhaust gas, a catalyst system in the exhaust tract and a dosing control device with a bus-compatible interface. The current operating parameters required for controlling the exhaust gas re-treatment device (AE) are fed to an interface module (SSMA) that contains functions for digitizing the operating parameters (SS) if required. The data derived from the operating parameters are fed via a serial bus system (CAN-Bus1) to the dosing controller (DSTG).
