  • Patent number: 10774784
    Abstract: The present invention relates to a low temperature, low frequency Stirling engine. Its special geometry allows for large heat exchanger surfaces and great regenerators in order to reach good “Carnoization” efficiency factors. Displacer and power piston may be connected with circular polymer based membrane sealings to the cylinder walls. The cold space of the Stirling Engine may cylindrically Surround the outer periphery of the working cylinder, making thermal isolation obsolete. The engine is for instance suited to operate as base power prime mover using thermal solar collectors and may be coupled with hot oil or pressurized water heat storages. In the reverse mode, the Engine works as effective Heat-Pump/Cooling Engine.

  • Patent number: 10767601
    Abstract: The exhaust gas recirculation (EGR) system provided herein utilizes a crossover (X) valve that is selectively activated at the direction of the electronic control module (ECM) to mix the high temperature (HT) and low temperature (LT) circuits of the EGR system under certain predetermined operating conditions. Thus, HT circuit fluid (at engine temperatures) is selectively fed into the LT circuit fluid (at ambient temperatures) to heat certain LT circuit components that are normally cooled by the LT circuit before starting the low pressure (LP) EGR in certain cold cycles. When this heating is finished, the X valve is closed to provide normal HT circuit/LT circuit fluid separation. The X valve can be controlled using a rotational actuator or the like. To avoid exposing the LT circuit to the high revolution-per-minute (RPM) operating conditions of the HT circuit, a HT bypass mechanism is provided.

  • Patent number: 10753272
    Abstract: A supercharging system includes a first supercharger including a first compressor; a second supercharger including a second compressor provided downstream of the first compressor, and a controller controlling the first and second superchargers. At least one of the first and second superchargers includes an electric motor for driving the first or second compressor. At least one of the first and second superchargers includes a turbine, and a nozzle vane that adjusts a flow-path area of the exhaust gas flowing into the turbine. When a charge amount of a battery is low, the controller sets an upper limit of an output command value for the motor to be lower than when the charge amount is not low, or starts regenerative operation of the motor. A vane control part controls an opening degree of the nozzle vane so that the flow-path area decreases with a control of the electric motor.

  • Patent number: 10746093
    Abstract: Methods and systems are provided for indicating whether a wastegate positioned in a vehicle exhaust system is stuck in a closed or open configuration. In one example, a method comprises activating an electric air compressor positioned in an intake of the engine and obtaining a first baseline air flow and a second baseline air flow in the exhaust system, and in response to an indication that the wastegate is potentially stuck open or closed, obtaining a test air flow measurement via activating the electric air compressor and comparing the test air flow in the exhaust system to the first and/or the second baseline air flow. In this way, the wastegate may be diagnosed under conditions of limited engine operation, such as that which may occur in hybrid electric vehicles.

  • Patent number: 10738723
    Abstract: An internal-combustion engine includes: a supercharger; an EGR passage connecting between an exhaust passage and an intake passage downstream of the supercharger; a control device controlling EGR; and an intake pressure sensor that detects a supercharge pressure being a gas pressure in the intake passage downstream of the supercharger. A comparison-target pressure is a higher one of a target supercharge pressure and an actual supercharge pressure detected by the intake pressure sensor. The control device compares the comparison-target pressure with an exhaust gas pressure in the exhaust passage. When the comparison-target pressure is higher than the exhaust gas pressure, the EGR is prohibited and an EGR valve is fully closed. When the comparison-target pressure is lower than the exhaust gas pressure, the EGR is permitted.

  • Patent number: 10704462
    Abstract: While an actuator is driven by an actuator driving unit with an operation amount for which the maximum value is limited by an operation amount limitation unit, if a state in which the actual opening degree of a wastegate valve does not coincide with a target opening degree has continued for a predetermined time period, driving by the actuator driving unit is attempted with an operation amount for which the maximum value limitation is relaxed by an operation amount limitation relaxing unit. Even after this, if the state in which the actual opening degree of the wastegate valve does not coincide with the target opening degree still has not been eliminated, an abnormality determination unit determines that abnormality has occurred in an opening degree control system for the wastegate valve.
