摘要： A half bearing includes: a semi-cylindrical bearing body having an inner circumferential surface that slides against a counterpart shaft; and a first groove formed in the inner circumferential surface so as to extend in a circumferential direction of the inner circumferential surface. In a cross section that is parallel with the circumferential direction and passes through the first groove, of the bearing body, an angle θ satisfies 90°≤θ≤105°, where the angle θ is formed by: a line connecting the inner circumferential surface side end of a mating surface located on a downstream side in a rotational direction of the counterpart shaft with the center point of a circular arc constituting an outer circumferential surface; and a line connecting an end of the first groove in the circumferential direction, on the upstream side in the rotational direction of the counterpart shaft, with the center point.

In a cross section that is parallel with the circumferential direction and passes through the first groove, of the bearing body, an angle θ satisfies 30°≤θ≤60°, where the angle θ is formed by: a line that connects the inner circumferential surface side end of a mating surface that is located on a downstream side in a rotational direction of the shaft with the center point of a circular arc that constitutes an outer circumferential surface; and a line that connects an end of the first groove in the circumferential direction, on the upstream side in the rotational direction of the shaft, with the center point.

摘要： A half bearing is provided with a first groove and a second groove on the inner circumferential surface side. The first and second grooves extend in the circumferential direction of the inner circumferential surface, and retain lubricating oil. The end of the first groove in the circumferential direction, on the downstream side in the rotational direction of the shaft (the end on the crush relief side), is located away from a crush relief so as not to reach the crush relief. Also, the end of the second groove in the circumferential direction, on the downstream side in the rotational direction of the shaft (the end on the crush relief 14 side), is located away from the crush relief so as not to reach the crush relief.

摘要： A half bearing includes circumferentially extending first and second grooves on the inner circumferential surface. The circumferential end of the first groove, on the rotational upstream side of the shaft, has an inclination angle θ1 of 135° formed by: a first imaginary line connecting the inner circumferential surface end of a mating surface and the origin of an outer circumferential surface; and a second imaginary line connecting the end of the first groove and the origin of the outer circumferential surface. The circumferential end of the second groove, on the rotational upstream side of the shaft, has an inclination angle θ2 of 135° formed by: a first imaginary line connecting the inner circumferential surface end of the mating surface and the origin of the inner circumferential surface; and a third imaginary line connecting the end of the second groove and the origin of the outer circumferential surface.

摘要： A control device controls an internal combustion engine including: an elastic wave sensor arranged and configured to output a signal responsive to the strength of an acoustic emission wave produced at a sliding portion; and a variable oil pump. The control device is configured to execute an oil pressure control such that the oil pressure approaches a target oil pressure according to an engine operating condition. This oil pressure control includes a first pressure-increase processing executed where an AE correlation value correlated with the strength or occurrence frequency of the acoustic emission wave detected by the elastic wave sensor is greater than a first threshold value. The first pressure-increase processing increases the target oil pressure associated with a first engine operating condition present when the AE correlation value becomes greater than the first threshold value, as compared to when the AE correlation value is not greater than that.

摘要： A slide bearing, in which halved members, made by dividing a cylinder parallel to the axial direction are disposed vertically, includes a groove circumferentially provided at the axial end of a lower halved member and a recess provided on an axially outer periphery of the groove, where a circumferential length of the recess is formed to be shorter than a length of the groove. The recess is formed such that its upstream end in the axial rotation direction aligns with an upstream end in the rotation direction of the groove. The recess is formed such that its downstream end in the rotation direction is located upstream relative to the circumferential center of the groove.
