Abstract
A heat exchanger cleaning system (HECS) includes an engine having an intake conduit and an exhaust port, and an EGR cooler having a cooler inlet in fluid communication with the engine exhaust port, a cooler outlet in fluid communication with the engine intake conduit, and an exhaust gas recirculation (EGR) valve disposed between the engine exhaust port and the EGR cooler. A first pressure sensor is disposed between the engine exhaust port and the EGR valve, and a second pressure sensor disposed in the engine intake conduit. A controller is in electrical communication with the EGR valve, the first pressure sensor, and the second pressure sensor. The controller is configured to implement a predetermined set of operating parameters for the engine and/or the EGR valve, wherein implementation of the predetermined set of operating parameters causes an increased flow velocity of exhaust gas through the EGR cooler.
