摘要： 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.

摘要： An evaporative emissions (EVAP) system for a vehicle includes a waste heat control valve configured to direct an exhaust gas from an exhaust treatment system, the waste heat control valve being positioned at a point downstream from a catalyst of the exhaust treatment system, a vapor canister configured to store a fuel vapor evaporated from a liquid fuel housed in a fuel tank of the vehicle, and a heat exchanger connected to (i) the fuel tank, (ii) the waste heat control valve, and (iii) the vapor canister, the heat exchanger being configured to (a) utilize the exhaust waste heat to evaporate the fuel vapor from the liquid fuel and (b) provide the evaporated fuel vapor to the vapor canister. A method of operating the EVAP system includes controlling the waste heat control valve and a fuel pump to provide the vapor canister with a desired amount of fuel vapor.

摘要： Engine coolant heating systems and methods that improve waste heat recovery. The systems and methods include a piped connection between the outlet of an exhaust gas recirculation cooler and the main exhaust pipe leading to the vehicle's tailpipe. The systems and methods also include at least one additional valve in the exhaust stream for directing the flow of exhaust appropriately given specific driving conditions.
