摘要：
In an internal combustion engine for a motor vehicle, having a piston bearing surface divided into regions of different loading and having recesses for retaining lubricant arranged at distances which are shorter in regions of high loading than in regions of lower loading in a region with high loading, the distance between the recesses decreases from one recess to the next in the direction toward top dead center area with the smallest distance being at the top dead center position of the piston.
