  • Patent number: 11125174
    Abstract: Systems and methods for simultaneously performing engine coolant stagnation and exhaust gas recirculation (EGR) cooler cooling in an engine include providing a coolant circuit configured to flow coolant through both a block of the engine and an EGR cooler of a cooled EGR (CEGR) system of the engine, a main pump on the coolant circuit that is driven by an electric motor or a crankshaft of the engine to pump coolant through a block of the engine, and a secondary pump on the coolant circuit that, when energized, is configured to pump coolant through the coolant circuit, and, during a cold start of the engine, de-energizing the electric motor or disconnecting the main pump from the engine crankshaft to stagnate coolant in the engine block and energizing the secondary pump to flow coolant through the EGR cooler of the CEGR system.
