The exhaust gas recirculation method and the device are suitable for use in an internal combustion engine. The apparatus includes an engine operating model that can output at least one engine operating characteristic, a negative feedback control section that receives feedback via emission values, and generates a negative feedback control signal based on a difference between a predetermined value of the exhaust gas recirculation and an emission value of the negative feedback , a positive feedback control section that receives a plurality of engine sensor inputs and generates the plurality of engine sensor inputs in connection with the engine operating model for generating a positive feedback control signal, the positive feedback control signal may change an exhaust gas flow of the exhaust gas recirculation before the plurality of engine sensor inputs Show deviation from a predetermined emission value, and a controller that the control signal of the negative feedback and the control signal of the positive return Receives coupling and accesses the engine operating model, wherein the controller controls the exhaust gas flow of the exhaust gas recirculation depending on the control signal of the negative feedback, the control signal of the positive feedback and the engine operating model. |
