摘要： Substances in external EGR gas are smoothly guided to a combustion chamber. An intake passage includes: a main intake passage including intake ports and communicating with a combustion chamber and having a supercharger interposed in the main intake passage; and a bypass passage branching off from the main intake passage upstream of the supercharger, and connected downstream of the supercharger; a flow rage adjustment valve changing a cross-sectional flow area of the bypass passage. The bypass passage is provided above the main intake passage, and includes an upper passage to which an EGR passage is connected.

摘要： An intake air filter box utilizing an intake air heater that inhibits the buildup of snow and ice within the intake air filter box, keeping the associated flow passages clear such that pressure loss is not adversely affected. This intake air heater can include an electric heater or a radiant heater coupled to the exhaust gas recirculation (EGR) system of the vehicle, or to another source of heated fluid. Preferably, the intake air heater is disposed on the “dirty” side of the filter disposed within the intake air filter box, adjacent to the intake air conduit and air intake of the vehicle. This is where the snow and ice accumulation occurs. A drain is provided in the bottom of the intake air filter box housing to allow the escape of water from the melted snow and ice, ensuring that this moisture is not delivered to the turbocharger and engine with the intake air.

摘要： An exhaust heat recovery device includes a heat exchanger that performs heat exchange between exhaust gas flowing in from a first exhaust gas conduit and a fluid as a heated object. Regarding the heat exchanger, a flow passage for the exhaust gas inside the shell is configured so that the exhaust gas flowing in from the exhaust gas inflow passage reaches a branch after contacting a plate in a division area and the exhaust gas not branched to an exhaust gas recirculation flow passage at the branch flows out to a second exhaust gas conduit after contacting a plate in a division area.

摘要： A method for controlling a vehicle cooling system 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 that is connected with the oil cooler, the heater, and the radiator. The method includes sensing driving conditions and operating the control valve when a warm mode is required to increase the temperature within the vehicle based on the sensed driving conditions. The control valve is operated based on first to third modes depending on a coolant temperature.

摘要： An internal combustion engine has an exhaust gas recirculation system for recirculating exhaust gases from the internal combustion engine into an intake region of the internal combustion engine. The exhaust gas recirculation system includes the following components: at least one exhaust gas cooler through which a first flow path for recirculating exhaust gas extends, having at least one first cooling stage and at least one additional cooling stage, at least one flap arrangement by which the at least one additional cooling stage can be connected, a bypass line through which a second flow path for recirculating exhaust gas extends and by which the exhaust gas cooler can be bypassed during the recirculation of exhaust gas, and an EGR valve having at least three possible positions.

摘要： A device is provided for exhaust gas recirculation (EGR), in particular in diesel engines, from the exhaust gas tract into the fresh air path of the engine, wherein a cooling device connected to the cooling system of the engine is provided within an EGR section as an exhaust-gas (EG)/coolant heat exchanger, with which an EGR valve for proportioning the EG recirculation rate is associated. The EGR valve is connected to a coolant, and the cooling device comprises an EG pre-cooler and an EG main cooler connected downstream of the EG pre-cooler. The EGR valve is installed between the EG pre-cooler and the EG main cooler in a valve housing between the EG pre-cooler and the EG main cooler. A method for EGR is provided as well.

摘要： An internal combustion engine includes a cylinder block, a cylinder-block passage, a cylinder head, a cylinder-head passage, cylinders, an introducing portion, a restricting wall, and communicating portions. The introducing portion is configured to introduce coolant flowing in the cylinder-head passage into an EGR cooler. The restricting wall is configured to restrict flow of the coolant from a section corresponding to the spark plug toward the introducing portion. The communicating portions cause the cylinder-block passage and the cylinder-head passage to communicate with each other. A direction perpendicular to both the extending direction of the central axis of each cylinder and the cylinder arrangement direction is defined as a predetermined direction. Certain one or certain ones of the communicating portions are arranged at positions closer to an intake manifold than the restricting wall in the predetermined direction.

摘要： A method includes operating an internal combustion engine producing, as a byproduct, exhaust gases. The flow of exhaust gases are segregated into a first, relatively hot flow and a second, relatively cold flow. The second flow is directed to an intake of the internal combustion engine for combustion with fresh intake air and fuel. Heat energy from the first flow is stored in a latent heat storage device. Heat energy is released from the latent heat storage device to reduce cold start emissions during a subsequent operation of the internal combustion engine after a period of shutoff.
