METHOD AND DEVICE FOR OPERATING AT LEAST TWO DISTRIBUTION VALVES OF DISTRIBUTION SYSTEM FOR SCR CATALYST SYSTEM
The invention relates to a method for operating at least two dosing valves (DV1, DV2) of a dosing system (32) for an SCR catalyst system, in which a respective adaptation factor (ADV1, ADV2) for each dosing valve (DV1, DV2) is ascertained on the basis of the sum of a proportional component (PDV1, PD...

| description | The invention relates to a method for operating at least two dosing valves (DV1, DV2) of a dosing system (32) for an SCR catalyst system, in which a respective adaptation factor (ADV1, ADV2) for each dosing valve (DV1, DV2) is ascertained on the basis of the sum of a proportional component (PDV1, PDV2) and an integral component (IDV1, IDV2), the opening time of the dosing valves being adapted by means of the adaptation factors (ADV1, ADV2) in such a way that the opening time of the dosing valves (DV1, DV2) is adjusted by means of the adaptation factors (ADV1, ADV2). In this way, the amount difference ([delta] m) is adjusted to a target predefined value (SV) that can be predefined.
本发明涉及一种用来运行用于SCR催化剂系统的配给系统（32）的至少两个配给阀（DV1、DV2）的方法，其中根据比例分量（PDV1、PDV2）和积分分量（IDV1、IDV2）的总和来分别求取针对每个配给阀（DV1、DV2）的适配因子（ADV1、ADV2），其中借助于适配因子（ADV1、ADV2）来如此适配配给阀的打开时间，使得将量差（Δm）调节至可预设的目标预设值（SV）。 |
