Patent ID: 6886545

Claim:
A control system for controlling an exhaust gas recirculation system having a control valve, said control system comprising: a processor for receiving a desired flow rate of at least one of a recirculating exhaust gas, an inlet air and a combined result thereof; at least one flow sensor sensing a flow rate of the fluid for which the processor receives the desired flow rate, and generating a sensor signal indicative of the sensed flow rate; wherein the processor is in communication with said at least one flow sensor, said processor receiving the sensor signal indicative of the sensed flow rate and generating a control signal based at least in part upon a deviation of the sensed flow rate from the desired flow rate; and wherein the control valve of the exhaust gas recirculation system is adapted to be in communication with said processor and to receive the control signal therefrom, and is adapted to adjust the proportion air versus recirculating exhaust gas based at least in part upon the control signal.
