Embodiments are directed toward an engine. In some embodiments, the engine includes a water pump and a balancer shaft. In some embodiments, the water pump has a plain bearing. In some embodiments, plain bearing is supplied with pressurized oil. In some embodiments, the balancer shaft drives the water pump as well as cam shafts.

A fluid pan for a motor vehicle has a main pan and a secondary pan that is separate from the main pan, wherein the main pan has a main space for fluid and a passage is provided on a side wall of the main pan. The secondary pan has a secondary space and an opening, wherein the secondary pan is attached to the side wall of the main pan in such a manner that the opening of the secondary pan connects to the passage of the main pan and thus the main space and the secondary space are fluidically connected.

The teachings herein are related to assemblies, such as oil pan assemblies, including a laminate bottom portion and a nut attached to the laminate bottom portion. The nut may provide a sealable opening to a cavity of the assembly. The laminate bottom portion preferably includes a polymeric layer sandwiched between two metallic layers. The nut preferably is a clinch nut.

A lubricant pan for a vehicle includes a receiving region in which a lubricant is at least temporarily receivable, a first wall element, and a second wall element. A temperature-control channel is disposed between the first wall element and the second wall element and a temperature-control medium is flowable through the temperature-control channel. A core that is porous and permeable to the temperature-control medium is disposed in the temperature-control channel between the first wall element and the second wall element. The temperature-control medium is introducible into the temperature-control channel via a first connector and the temperature-control medium is dischargable from the temperature-control channel via a second connector.

An engine oil lubrication system includes an oil flow control baffle disposed in the sump of the oil pan. The baffle may be detachably mountable in the sump of the oil pan. The baffle may be configured to prevent oil returning to the sump from the engine from short-circuiting and flowing directly to the oil pump intake. The baffle creates a circuitous flow path which forces mixing of the returning oil before being drawn into the oil pump intake nozzle via increasing resonance time of the oil in the sump to enhance cooling. The present disclosure further provides a modular engine mounting system which extends the number of engines and vehicle chassis which can utilize a single oil pan to mount to the chassis. Interchangeable mounting flanges are provided having different bolting patterns compatible with the different chassis.

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.

An internal combustion engine, having a cylinder crankcase delimiting a crank chamber and a lubricant pan accommodating a lubricant sump, which has a lubricant pan upper part arranged between the crank chamber and the lubricant sump and a lubricant pan lower part fastened on the lubricant pan upper part. Multiple ridges originate from a base component of the lubricant pan upper part in the direction of the lubricant sump, which ridges partially intersect and thus form chambers which are peripherally closed in section between them, and lubricant passage openings formed in the lubricant pan upper part open into at least part of the chambers, via which openings the crank chamber and the lubricant sump are fluidically connected.
