Abstract: Methods and systems for controlling the conditions of a coolant for the cooler of an exhaust gas recirculation system are disclosed. The system determines coolant pressure at predetermined location of the cooler. The system also senses the actual temperature of the coolant at a predetermined location of the cooler. The system also determines a coolant boiling temperature at the determined coolant pressure. Using the determined coolant pressure, the system may control engine operation so as to prevent coolant from reaching boiling in the cooler. An engine derate power factor may be determined to control the amount of fuel delivered to the engine, such as reducing the amount of fuel delivered through the fuel injectors. The amount of delivered fuel may be derated until an adjusted coolant temperature falls a predetermined amount below the coolant boiling temperature.

Abstract: A method for dislodging exhaust gas deposits from an exhaust gas recirculation (EGR) cooler (26) associated with an engine includes the steps of providing at least one on-board gas source (S) for providing a gas (G) at a superatmospheric pressure, and placing the EGR cooler in fluid communication with the gas source through a supply conduit (44, 144). The supply conduit (44, 144) includes at least one valve (V) that is selectively operable to a closed condition closing the supply conduit and to an open position opening the supply conduit. The method also includes the step of operating the at least one valve (V) from the closed condition to the open condition to allow the superatmospheric gas (G) to flow through the supply conduit (44, 144) to the EGR cooler (26).

Abstract: A method of controlling cooling flow through a coolant system of an internal combustion engine having an electronic control module, a cooling throttle, an EGR cooler, and an interstage cooler is provided. A pressure within a coolant system is determined. A temperature within the coolant system is determined. A temperature of exhaust gas exiting an EGR cooler is determined. A temperature of intake air exiting an interstage cooler is determined. A position of a cooling throttle within the coolant system is adjusted based upon at least one of the determined pressure within the coolant system, temperature within the coolant system, temperature of exhaust gas exiting the EGR cooler, and temperature of intake air exiting an interstage cooler being above respective predefined thresholds to adjust fluid flow within the coolant system.
