Abstract

An exhaust gas recirculation system for a power source, has at least one inlet port configured to receive at least a portion of a flow of exhaust produced by the power source. The exhaust gas recirculation system also has an electrode disposed upstream of the at least one inlet port and configured to charge particulate matter in the flow of exhaust. The exhaust gas recirculation system further has at least one collection surface configured to allow the at least one electrode to repel the charged particulate matter away from the at least one inlet port towards the at least one collection surface.
