A device for the supply of lubricant with a lubricant pump (101), which has a driveshaft (103), and a motor (107). The motor (107) is designed to drive the driveshaft (103). At least one clutch (109, 111, 113) serves to establish and/or interrupt a force flow between a shaft in the force flow of a transmission and the driveshaft (103).

A system determines which propulsion-generating vehicle or vehicles in a group of propulsion-generating vehicles have an increased risk for oil carryover during operation at an idle setting for at least a designated oil carryover commencement time period. The system also determines a power requirement for the group of propulsion-generating vehicles in the vehicle system. The system determines power outputs for the propulsion-generating vehicles in the group such that the propulsion-generating vehicle or vehicles having the increased risk for oil carryover do not operate at an idle setting for longer than the designated oil carryover commencement period, and that the power generated by the group of propulsion-generating vehicles meets the power requirement that is determined.

A fluid delivery system for an internal combustion engine and a method of monitoring the fluid delivery system are described. The systems and methods monitor and determine various fluid quality parameters and filter element pressure drop, which can be used to determine real-time estimates of remaining useful life for both the filter element and the fluid. The respective remaining useful life calculations are used by the described systems and methods to determine change intervals for the fluid and the filter element. The change intervals can be synchronized by the systems and methods to reduce the amount of down time due to servicing of the fluid delivery system.

A vehicle engine pump assembly (100, 1000, 1100) has a gerotor pump (102), a mechanical drive (106) driven by the engine and an electrical drive (104). A controller (107) selectively engages the mechanical drive to boost pumping effort when required via a clutch.

The present invention improves the drainability of lubricating oil. The present invention comprises: a rotating shaft (14); a journal bearing that is provided to the rotating shaft (14) and rotationally supports the rotating shaft (14); a bearing housing part that houses the journal bearing; and a drain oil space chamber (47) that acts as an oil drainage passage that communicates with the bearing housing part, is provided along the periphery of the rotating shaft (14), and is formed to open downward. Within a region that is in and above a horizontal plane H that passes through the center of the rotating shaft (14), the smallest cross-sectional area of the oil drainage passage in a radial-direction cross-section thereof is on the anterior side in the rotational direction of the rotating shaft (14) with respect to a vertical plane P that passes though the center (O) of the rotating shaft (14), and the largest cross-sectional area of the oil drainage passage in the radial-direction cross-section is on the posterior side in the rotational direction of the rotating shaft (14) with respect to the vertical plane that passes through the center (O) of the rotating shaft (14).
