摘要： An exhaust gas recirculation structure includes an EGR cooler and an EGR duct, and the EGR duct includes an inflow portion into which the exhaust gas flowing out from the EGR cooler flows, a flow path, and an outflow portion from which the exhaust gas flows out. The flow path is provided such that the height on the side of the inflow portion is lower than the height on the side of the outflow portion, and has a region in which the distance between the center line of a flow path cross section of the flow path and a line along the lowest end in the height direction gradually increases from the outflow portion side toward the inflow portion side.

摘要： An exhaust heat recovery device includes: a first flow path member; a second flow path member adjacent to the first flow path member, and which includes a heat exchange unit configured to perform heat exchange between exhaust gas flowing in the second flow path and a refrigerant; a valve mechanism configured to switch between opening and closing of the first flow path and the second flow path; and a drive unit which includes a drive shaft configured to rotate the rotation shaft portion. The second flow path member is inclined with respect to a flow direction of the exhaust gas in the first flow path, and the drive shaft extends toward the first flow path member and is connected to the rotation shaft portion in a region formed on a lateral side of the second flow path member when viewed in an axial direction of the drive shaft.

摘要： A controlling method of vehicle exhaust gas recirculation, an apparatus and an electronic device are provided in vehicle field. Before the GPF/DPF starts to work, controlling the EGR to cool the temperature of the recycled gas at a lowest gas temperature required being entranced into the engine; and after the GPF/DPF starts to work, according to a gas temperature change and an intake flow change of an air intake of the EGR, adjusting an opening of a valve arranged in a vent of the EGR and a working power of a pump arranged in a liquid duct of the EGR, for making the EGR to cool the gas recycled by the EGR in a safe temperature range required by the engine. The controlling method is associated controlled with a cooling system of the EGR, for ensuring the recycled exhaust gas temperature and the EGR rate in a suitable range.

摘要： An EGR cooler includes a tube assembly formed by stacking a plurality of tubes in which exhaust gas flows and a cover plate having a mounting portion formed concavely to mount the tube assembly thereon. A baffle is mounted at the tube assembly and adjusts flow of coolant inflow from a cylinder block. An inlet cover is installed on a first side of an outer surface of the cover plate to supply the exhaust gas to each tube and an outlet cover is installed on a second side of outer surface of the cover plate to exhaust the exhaust gas from each tube. At least one coolant passage in which the coolant flows is formed between the plurality of tubes.

摘要： A waste heat recovery system (100) is provided. At least one heat exchanger (104) is fluidically coupled to a waste heat source (102) and is configured for selectively recovering heat from the waste heat source (102) to heat a working fluid (108). An energy conversion device (112) is fluidically coupled to the at least one heat exchanger (104) and is configured to receive the working fluid (108) and to generate an energy for performing work or transferring the energy to another device using the heat recovered from the waste heat source (102). A condenser (122) is fluidically coupled to the energy conversion device (112) and configured to receive the working fluid (108) from the energy conversion device (112) and to condense the working fluid (108) into a liquid phase.

摘要： A system and method operate by, while an engine is operating, automatically determining whether the engine is in a designated state for EGR cooler cleaning. The EGR cooler is operably coupled to the engine to receive hot EGR from an exhaust of the engine and to provide cooled EGR to an intake of the engine. The system and method also include, responsive to the engine not being in the designated state, automatically preventing a water pump system from introducing a cleaning liquid into a gas inlet of the EGR cooler.

摘要： A method for controlling a cooling system for a vehicle is provided. The system includes an engine, an EGR cooler, an oil cooler, a heater, a radiator, and a controller. The engine, the EGR cooler, the oil cooler, the heater, and the radiator are respectively connected through a coolant line and coolant circulates through the engine, the EGR cooler, the oil cooler, the heater, and the radiator by operation of a water pump. The controller receives the coolant from the engine and operates a control valve connected with the oil cooler, the heater, and the radiator. The method includes: sensing driving conditions and operating the control valve when a cooling mode is required to decrease the temperature within the vehicle based on the sensed driving conditions. The control valve is operated based on modes controlled depending on a coolant temperature, and among the plurality of modes, one is iteratively performed.
