Method and apparatus for control of heating an exhaust gas purification system of internal combustion engines |
摘要 |
Exhaust flow rate of through the purification system (12) is measured or modeled. Actual temperature is measured or modeled in selected regions of the system (12), and compared with a desired temperature value, forming a temperature difference. As a function of this and the flow rate, a desired energy input into the system is determined. Parameters characterizing the heating stage are so set and imposed, that the required energy input is supplied, at least approximately. The required energy input is controlled as a function of exhaust gas composition. An Independent claim is made for corresponding equipment. |
