  • Patent number: 10655534
    Abstract: A turbocharger system includes a valve assembly with an inlet, a first outlet, and a second outlet. The inlet is configured for receiving flow of an exhaust gas from an engine. The valve assembly includes a valve structure disposed within a housing. The valve structure is configured to rotate about an axis of rotation between a first position and a second position. The valve structure defines a nonlinear flow passage with an axial upstream end and radial downstream end. The valve structure, in a first position, directs exhaust gas from the inlet to the first outlet and closes off the second outlet. The valve structure, in the second position, directs exhaust gas from the inlet to the second outlet and closes off the first outlet.

  • Patent number: 10655529
    Abstract: An engine system includes an internal combustion engine, a compressor, a high-temperature coolant circulation circuit, a low-temperature coolant circulation circuit, an intercooler, and an electronic control unit. The intercooler is configured to transfer heat of the high-temperature coolant to the low-temperature coolant via intake air. An in-compressor passage of the compressor is arranged in the low-temperature coolant circulation circuit at a location at which the low-temperature coolant that exits from an in-cooler low-temperature water passage during a predetermined period from beginning of cold start is introduced into the in-compressor passage without passing through a low-temperature radiator. The electronic control unit is configured to increase the flow rate of the low-temperature coolant that flows through the low-temperature coolant circulation circuit during the predetermined period as compared to the flow rate after the predetermined period.

  • Patent number: 10648403
    Abstract: In order for charge air to be conducted with the lowest possible losses in pressure in a turbocharger including a blow-off valve, a flow-guiding element in an inlet region is designed such that neutral zones are formed at the flow openings. The flow openings recirculate charge air from the pressure side to the suction side when the blow-off valve is opened. The flow-guiding element avoids vortices and therefore losses in pressure in the region of the flow openings.

  • Patent number: 10598085
    Abstract: A hybrid turbocharger includes a first power conversion unit to convert direct-current power into alternating-current power to be output to a generator motor, a smoothing capacitor between direct-current buses, and a control unit that controls the first power conversion unit so as to cause actual generator motor speed to comply with an engine speed command of the generator motor input from an upstream controller during a motoring operation of the generator motor. The control unit changes the engine speed command to a value which is equal to or greater than the actual generator motor speed if the engine speed command of the generator motor is less than the actual generator motor speed and a direct-current bus voltage is equal to or greater than a predetermined first threshold value during the motoring operation. Accordingly, the direct-current bus voltage can be prevented from increasing during the motoring operation.

    Abstract: An electronic control unit of an internal combustion engine is configured to control the fuel injection valve and to control a spark plug if necessary such that fuel is combusted by pre-mixture compression ignition combustion or flame propagation combustion. The electronic control unit is configured to perform homogeneous combustion in a flame ignition operation range when switching failure has not occurred, the homogeneous combustion being combustion in which fuel homogeneously diffused into the combustion chamber is ignited using the spark plug and is combusted by flame propagation combustion. The electronic control unit is configured to perform spray-guided stratified combustion in a second operation range when the switching failure has occurred, the spray-guided stratified combustion being combustion in which fuel in the fuel injection path is ignited using the spark plug and is combusted by the flame propagation combustion.
