Abstract:
An exhaust gas recirculation control system comprises a pressure condition evaluation module and a protection module. The pressure condition evaluation module evaluates at least one of vane movement of a turbocharger and engine pressure. The protection module selectively controls an exhaust gas recirculation valve based on the at least one of the vane movement of the turbocharger and the engine pressure.
