  • Patent number: 10590826
    Abstract: There is provided a secondary air introduction device configured to introduce air into an exhaust port provided in a cylinder head of an engine by using a negative pressure in the exhaust port. A back-flow restriction member is provided between a reed valve and the exhaust port in an air introduction passage, and includes a plate part intersecting with an extension direction of the air introduction passage. The plate part has an air passing region in which the air flowing through the air introduction passage from an air intake unit toward the exhaust port is enabled to pass therethrough and a back-flow cutoff region in which exhaust air, which flows in a direction of directly colliding with at least a valve body of the reed valve, of exhaust air flowing back through the air introduction passage from the exhaust port is cut off.

  • Patent number: 10590827
    Abstract: Methods and systems are provided for filtering particulate matter in an exhaust passage of an engine system. In one example, a method may include during a cold start condition comprising an engine temperature being less than a threshold engine temperature, directing engine exhaust gas to an exhaust particulate filter, and during a warm engine condition, directing engine exhaust gas to bypass the exhaust particulate filter, wherein the warm engine condition comprises the engine temperature being greater than or equal to the threshold engine temperature and fuel being combusted in the engine. In this way, the exhaust particulate filter may be reliably regenerated during engine shutdown events such as DFSOs while reducing filter degradation, and lowering PM emissions.

  • Patent number: 10590829
    Abstract: The invention of the present application relates to a control device and a control method for a cooling device. A cooling device includes a first cooling water passage of a cylinder head, a second cooling water passage of a cylinder block, a control valve that changes a ratio between a flow rate of the first cooling water passage and a flow rate of the second cooling water passage, and a water pump. Then, the control device controls the control valve so that a ratio of the flow rate of the first cooling water passage increases when a cooling water circulation flow rate is insufficient due to failure of the water pump. Accordingly, it is possible to suppress damage of an engine body while suppressing deterioration in traveling performance of a vehicle when failure occurs in the water pump.

  • Patent number: 10590839
    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.

  • Patent number: 10590848
    Abstract: A flight vehicle has a propulsion system that includes an air inlet, an isolator (or diffuser) downstream of the air inlet, and a combustor downstream of the isolator. The isolator includes an obstruction that protrudes inwardly from an inner wall of the isolator, into the flow channel in which air flows through the isolator. The obstruction diverts the flow to either side of it. Downstream of the obstruction the flow on either side of the obstruction comes together again, leading to mixing of the flow, for example including mixing of low energy and boundary layer flow with high energy flow. This mixing of flow may make for a more uniform flow at the exit of the isolator. In addition the obstruction may help fix the location of shocks within the isolator, providing longer flow mixing length in the isolator.

  • Patent number: 10590863
    Abstract: A regulating device for an internal combustion engine includes an exhaust gas recirculation pipe which opens into an intake pipe which are both formed in a housing, and a regulating element eccentrically mounted on a shaft. The shaft is arranged perpendicular to a center line of the intake pipe and the exhaust gas recirculation pipe. The regulating element includes a first surface, a second surface, and guide ribs arranged on the first surface. In a first end position of the regulating element, in which the intake pipe is at least throttled upstream of an opening of the exhaust gas recirculation pipe, a normal vector of the first surface points to an upstream side of the intake pipe. In a second end position of the regulating element, in which the exhaust gas recirculation pipe is closed, a normal vector of the second surface points to the exhaust gas recirculation pipe.

  • Patent number: 10590867
    Abstract: A method of operating a compoundable engine that includes a turbine having a turbine shaft and an intermittent internal combustion engine having an engine shaft. The engine shaft is rotated at a first rotational speed. The turbine is driven by exhaust gases of the intermittent internal combustion engine to rotate the turbine shaft while the engine shaft rotates independently from the turbine shaft. A rotatable load is driven with the turbine shaft. A rotational speed of the engine shaft is increased from the first rotational speed until the turbine shaft reaches a predetermined rotational speed. After the turbine shaft has reached the predetermined rotational speed, the rotational speed of the engine shaft is adjusted until the turbine shaft and the engine shaft are drivingly engageable with each other, and the turbine shaft with the engine shaft are engaged such that both are in driving engagement with the rotatable load.

  • Patent number: 10590877
    Abstract: A method, device and system for detecting and counteracting a runaway condition in a diesel engine system. The diesel engine system includes an inlet for supplying combustion air to a diesel engine, and an exhaust for relieving the diesel engine from exhaust gas. The diesel engine system further includes an exhaust gas recirculation system for selectively allowing exhaust gas from the exhaust to enter the inlet. A first gas flow path actuator is included in the exhaust gas recirculation system, and a second gas flow path actuator is included in the exhaust. The method, as performed by the system, comprises detection of an actual or potential runaway condition, and in response thereto deprives the diesel engine of oxygen. Depriving of oxygen is performed by opening the first gas flow path actuator and closing the second gas flow path actuator to cause stalling of the diesel engine.
