Method for automating a resistance compensation on a feed pump of an SCR system and SCR system for using the method

摘要

The present invention relates to a method of automating a resistance compensation on a feed pump (14) of an SCR system (10) by activating a resistance balance by interrogating conditions to enable resistance compensation, measuring a total resistance (RGT) at an adaptation temperature, determining a first virtual one Resistance value (R1) and determining a second virtual resistance value (R2) and storing the first and second resistance value (R1, R2) in a control unit (22) and an SCR system for carrying out such a method.
