    Abstract: A method (100) of diagnosing a fuel gas supply arrangement (1, 1') is disclosed. The fuel gas supply arrangement (1, 1') comprises a pressure tank (3), a fuel pressure reducer (6, 6'), a first conduit assembly (c1) connecting an inlet (9) of the fuel pressure reducer (6, 6') to the pressure tank (3), and a second conduit assembly (c2) connecting an outlet (9') of the fuel pressure reducer (6, 6') to propulsion system (60). The method (100) comprises the steps of obtaining (110) pressure data at multiple consecutive occasions, wherein the pressure data is representative of a pressure in the second conduit assembly (c2) during zero-flow conditions over the fuel pressure reducer (6, 6'), and diagnosing (130) an operational performance of the fuel pressure reducer (6, 6') by analysing the obtained pressure data. The present disclosure further relates to a control arrangement (21), a computer program, a computer-readable medium (200), a fuel gas supply arrangement (1, 1'), and a vehicle (2).

    Abstract: A method (100) of operating an internal combustion engine (1). The method (100) comprises, during idling of the engine (1) operating (110) the engine (1) in a first mode of operation (m1) by controlling (111) a flow control assembly (6) to provide a nominal amount of gas pumped into an exhaust system (4) and controlling (112) an exhaust throttle (5) to the closed state, operating (120) the engine (1) in a second mode of operation (m2) by controlling (121) the flow control assembly (6) to provide a reduced amount of gas pumped into the exhaust system (4) and controlling (122) the exhaust throttle (5) to an open state, and switching (130) in an alternating manner between the first and second modes of operation (m1, m2). The present disclosure further relates to a control arrangement (21), a computer program, a computer-readable medium (200), an engine (1), and a vehicle (2).

    IPC: H02K1/20

    Abstract: A stator (120) for an electrical machine (100), wherein the stator (120) comprises a plurality of stacked stator sheets (121). Each stator sheet (121) comprises a plurality of radially extending stator slots (125), radially arranged about a common central axis of the stator (120), wherein the stator slots (125) are located apart, equidistantly from each; and a plurality of holes (140), each arranged at a radial end-section (127) of a respective stator slot (125); and wherein the radially extending stator slots (125) of two adjacent stator sheets (121) are axially aligned with each other, while at least some adjacent holes (140) of two adjacent stator sheets (121) are displaced in relation to each other, thereby forming a respective flow obstruction (320) in an axially extending cooling channel segment (310) formed by the holes (140).

    Abstract: The disclosure concerns a fastening device (2) for fastening a first and a second container (4', 4") to a structure of a vehicle (1), the fastening device (2) comprises: an elongated member (16) with external engagement members (18), a first abutment (20), a displaceable member (22), a guide arrangement (12), comprising a second abutment (24), a holed member (28), and a resilient compressible member (32). The elongated member (16) extends along an axis (19) and the displaceable member (22), the guide arrangement (12), the resilient compressible member (32), and the holed member (28) are aligned along the axis (19). The elongated member (16) extends through the displaceable member (22) and at least partially through the guide arrangement (12) for engagement between external engagement members (18) of the elongated member (16) and internal engagement members (30) of the holed member (28) for compression of the resilient compressible member (32).

    IPC: B60L58/12

    Abstract: The invention relates to a method performed by a control arrangement for setting a remaining Distance to Empty parameter in an electric vehicle, wherein the control arrangement is configured to estimate a first remaining Distance to Empty value at least based on a remaining State of Charge of the vehicle's energy storage. The method comprises when the first remaining Distance to Empty value is estimated to be below a Distance to Empty threshold value determining a second remaining Distance to Empty value at least based on an actual distance travelled since the first remaining Distance to Empty value was estimated to be below the Distance to Empty threshold value. The method further comprises setting the remaining Distance to Empty parameter at least based on the second remaining Distance to Empty value. Hereby, the risk of rapid decrease of the Distance to Empty parameter at low battery charging level is mitigated and the Distance to Empty parameter will be perceived as correct which means that unnecessary stress is avoided when low State of Charge of the vehicle's energy storage is reached. The invention also relates to a control arrangement, a vehicle comprising the control arrangement, a computer program, and a computer-readable medium.
