  • 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.

  • Patent number: 10677385
    Abstract: A conduit connection assembly includes a first conduit part and a second conduit part, assembled to form a conduit connection delimiting a first fluid conducting volume from a second fluid conducting volume.

  • Patent number: 10655871
    Abstract: The disclosure describes trench-confirmable geothermal reservoirs that can snugly abut trench walls (that may be of virgin, compacted earth) for facilitating heat exchange and flow liquid from one lower end to an opposing top end, and vice versa, depending on desired heat exchange. The direction can be reversed for summer and winter heat/cooling configurations. A series of the reservoirs may be used for appropriate heat transfer. The water volume of the reservoirs is relatively large and slow moving for good earth heat conduction.

  • Patent number: 10590836
    Abstract: Methods and systems are provided for improving surge control in a boosted engine system configured with an electric motor to provide electrical boost assistance. Tip-in and tip-out surge are addressed by increasing the opening of a compressor recirculation valve and coordinating the recirculation valve opening with adjustments to an exhaust waste-gate position and a power output by the electric motor. The adjustments enable an intake airflow to be provided that operates the compressor outside a surge region while providing a target boost pressure as operator torque demand increases or decreases.
