Claim 0:
1. A heat exchanger cleaning system (HECS), comprising:
an engine;
an engine intake conduit, and an engine exhaust port;
an exhaust gas recirculation (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 EGR valve disposed in fluid communication with and between the engine exhaust port and the EGR cooler;
a first pressure sensor disposed in fluid communication with and between the engine exhaust port and the EGR valve;
a second pressure sensor disposed in the engine intake conduit; and
a controller in electrical communication with the EGR valve, the first pressure sensor, and the second pressure sensor;
wherein 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.
