A system for providing lubrication to a machine. The system comprises at least one ultrasound sensor positioned to detect sound emanating from at least one lubrication point of the machine, and at least one auto-lubrication device configured to provide lubrication to the at least one lubrication point. The at least one auto-lubrication device is controlled to provide lubrication to the at least one lubrication point based at least in part on sound detection data from the at least one ultrasound sensor.

Present embodiments relate to an oil pan assembly. More specifically, but without limitation, present embodiments relate to an oil pan assembly including a windage tray which cooperates with the oil pan.

A vehicular internal combustion engine is equipped with a supercharger, a drain pipe for draining lubricating oil in the supercharger, a cylinder block including a first oil passage, and a PCV separator including a second oil passage connected to an outlet of the drain pipe and an inlet of the first oil passage.

A two-part oil pan for an internal combustion engine has a box portion and a pan portion. The pan portion forms a floor of the oil pan and the box portion forms a pan wall of the oil pan. On a peripheral edge having a peripheral first sealing surface on the pan portion and a peripheral second sealing surface on the box portion, the box portion and the pan portion are interconnected in a sealed manner by means of first connection means. The pan portion and the box portion additionally are interconnected by at least one second connection means which is arranged within the edge and additionally at a distance from said edge.

A composite oil pan for a work vehicle engine and a method of forming the composite engine oil pan include forming a sheet of metal into a first pan and open molding a fiber-reinforced polymer resin onto the first pan forming a second pan. The first pan has a first bottom wall and first peripheral walls extending from edges of the first bottom wall to define a sump, the first peripheral walls terminating in a first peripheral flange. The second pan has a second bottom wall and second peripheral walls abutting the first bottom wall and the first peripheral walls, the second peripheral walls terminating in a second peripheral flange. The first pan defines a thin metal structure with an inner surface extending across the first bottom wall, first peripheral walls and first peripheral flange; the second pan reinforces the first pan without abutting the inner surface.

The invention relates to a fluid drain plug (10) for a fluid reservoir (50) with a drain hole (51), the plug having an extension in an axial direction (A) and comprising a body part (16) rotationally insertable into the drain hole (51), the body part having a proximal axial end (15), a distal axial end (17) and a substantially circular cross section with an outer surface (18), wherein the body part comprises a drain channel (92) having an inlet (91) located at the distal axial end and an outlet opening (94) disposed on the outer surface (18), the body part further comprising a bayonet-type connection slot (40) for accommodating a part of a radial projection (52) of a circumferential surface surrounding the drain hole (51), the bayonet-type connection slot being disposed on the outer surface and comprising an entrance (40a) at the distal axial end, a first path (41) and a second path (42), the first path (41) extending from the entrance, in the axial direction (A) and in one circumferential direction (C), to a first path terminal portion (70), wherein the first path terminal portion (70) is adapted to accommodate the radial projection (52), and the second path (42) extending from the first path terminal portion, in the axial direction (A) and in an opposite direction to the one circumferential direction (C), to a second path terminal portion (72), wherein the second path terminal portion (72) is adapted to accommodate the radial projection.

A tank device of an oil circuit of an aircraft engine for stocking oil inside an interior space that is delimited by a wall, having at least one appliance for introducing oil into the interior space. By means of the appliance for introducing oil, the area of the wall that is arranged above a minimal filling level, as it occurs during operation of an aircraft engine, can be impinged with oil.

A lubricant system for supplying lubrication to a component in a turbine engine includes a lubricant reservoir, a supply line fluidly coupling the lubricant reservoir to the component in the turbine engine, a scavenge line fluidly coupling the component to the lubricant reservoir, and a bypass line fluidly coupling the supply line to the scavenge line and bypassing the component.

A cooling structure for an outboard motor comprises an oil case which has an oil chamber for storing lubricant oil for an engine. Said cooling structure further comprises: a main exhaust gas passage which guides exhaust gas to a lower side; a cooling water outbound path which guides cooling supply water taken from outside the outboard motor to an upper side, and cools the periphery of the main exhaust gas passage in the oil case by means of the cooling supply water; a cooling water inbound path which guides cooling discharge water that has cooled the engine to the lower side and cools the oil chamber by means of said cooling discharge water; and a mixed fluid passage which, on a side below the oil case, cools the exhaust gas by mixing the exhaust gas and the cooling discharge water.
