Patent ID: 7979196

Claim:
A power system, comprising: an exhaust producing engine; an exhaust system configured to direct exhaust gases produced by the engine away from the engine; an exhaust gas recirculation system, including: an exhaust gas recirculation flowpath; an air intake system of the engine, wherein the exhaust gas recirculation flowpath is configured to route a portion of exhaust gases produced by the engine back to the air intake system; and an exhaust gas recirculation valve configured to regulate the flow of exhaust gases through the exhaust gas recirculation flowpath; a monitoring system configured to monitor one or more operating parameters of at least one component, the at least one component for which one or more operating parameters are monitored includes an air-to-air after cooler, an exhaust gas recirculation cooler, or an air intake system passage in the exhaust gas recirculation system; and a controller configured to: determine, based on the one or more monitored operating parameters, a maximum flowrate value for each component for which operating parameters are monitored, wherein each maximum flowrate value represents the maximum exhaust gas recirculation flowrate that may be utilized without exceeding a predetermined operating limit of the monitored component with which the respective maximum flowrate value is associated; and control the exhaust gas recirculation valve, based on the determined maximum flowrate value, to result in an exhaust gas recirculation flowrate no greater than the determined maximum flowrate value.
