Abstract
An assembly for cooling oil for an internal combustion engine may include a piston having a piston head and a piston skirt. The piston head may include a piston crown with an undersurface having an outer region configured as a guiding surface for the cooling oil, a circumferential ring part, and, in a region of the circumferential ring part, a circumferential cooling channel with at least one feed opening for the cooling oil. The assembly may also include a first oil spray nozzle for creating a first cooling oil jet directed at the feed opening, and a second oil spray nozzle for creating a second cooling oil jet directed at the guiding surface such that the second cooling oil jet may deflect and flow along the guiding surface in a direction of the undersurface. At least the first oil spray nozzle may be positioned below the piston skirt.
