SCR-Emissionssteuerungssystem |
摘要 |
An emissions control system is disclosed. The emissions control system may have an SCR device that receives a flow of exhaust. The emissions control system may also have an injector that introduces a reduction agent into the flow of exhaust at or upstream of a catalyst within the SCR device. The emissions control system may have a controller in communication with the injector, the controller being configured to calculate a first amount of the reduction agent by using an approximation that at least one of a plurality of SCR reactions must be completed before the remaining SCR reactions commence. The controller may also be configured to adjust the injector according to at least the first amount. |
