Abstract
A control system for controlling an exhaust gas recirculation system having a control valve is provided. The control system includes at least one flow sensor sensing a flow rate of at least one of a recirculating exhaust gas, an inlet air and a combined result thereof, and generating a sensor signal indicative of the sensed flow rate. A processor in communication with the at least one flow sensor receives the sensor signal indicative of the sensed flow rate and generates a control signal based at least in part upon the received sensor signal. The control valve of the exhaust gas recirculation system is adapted to be in communication with the processor and to receive the control signal therefrom, and is adapted to actuate based at least in part upon the control signal.
