AFTERTREATMENT SYSTEM HAVING DYNAMIC INDEPENDENT INJECTOR CONTROL |
| 摘要 |
An aftertreatment system is provided for an engine. The aftertreatment system may have at least one exhaust passage and a plurality of reductant injectors that are controllable to dose reductant into the at least one exhaust passage. The aftertreatment system may also have at least one sensor configured to generate a signal indicative of an exhaust parameter and a controller in communication with each of the plurality of reductant injectors and the sensor. The controller may be configured to dynamically adjust the dosing of the plurality of injectors, wherein adjusting the dosing includes adjusting at least one of an injector timing, an injector sequence, and a grouping of the plurality of injectors that are simultaneously injecting based on the signal. |
