摘要： A motor includes a rotor, a stator including a stator core and a coil, a housing, and a first annular member that provides sealing between a first end surface of the stator core in a direction of an axis of the stator core and an inner wall surface of the housing. The first annular member has first holes configured to be passed through by a refrigerant injected toward a first coil end of the coil, the first coil end protruding from the first end surface. The first annular member includes a first section in which at least two of the first holes are arranged in a circumferential direction of the first annular member at a first interval, and a second section in which at least two of the first holes are arranged in the circumferential direction at a second interval that is larger than the first interval.

摘要： A motor may include a rotor; a stator comprising a stator core and a coil; a housing that houses the rotor and the stator; and a first annular member that provides a seal between a first end face of the stator core in an axial direction of the stator core and an inner wall surface of the housing. The first annular member may have a cylindrical shape about an axis of the stator core. The first annular member may include at least one first hole and at least one second hole through which refrigerant is injected toward a first coil end. The at least one first hole may be located on a first plane perpendicular to the axis. The at least one second hole may be located on a second plane that is perpendicular to the axis and spaced apart from the first plane in the axial direction.

The first annular member may include a plurality of first holes through which refrigerant is injected toward a first coil end of the coil protruding from the first end face of the stator core. The plurality of first holes may include a first large hole and a first small hole, and the first small hole may have an opening area smaller than an opening area of the first large hole.

摘要： A controller calculates a predicted value of the exhaust pressure between a catalyst and a filter for a case in which engine fuel containing no manganese is used continuously. Also, the controller calculates a correlation value proportional to the amount of heat received by the catalyst when the catalyst temperature is higher than or equal to the adhesion temperature of manganese oxide. Further, the controller determines that there is a removal requirement for removing manganese oxide from the catalyst when the difference between the predicted value and the detected pressure of the exhaust pressure between the catalyst and the filter is greater than a specified determination value, and the correlation value is greater than or equal to a specified determination value. The controller executes the removal process by performing fuel amount increase control when it is determined that there is a removal requirement.
