Abstract
A lubricant oil transport device and method is provided in an internal combustion engine using wet sump lubrication. Near the connecting rod and the crankshaft cheeks, which are disposed exteriorly in the transverse acceleration and/or inclination direction and lie opposite a decentralized oil suction system, the oil repulsion part is configured to cause a centrifugal flow for oil transport in the oil pan area opposite the transverse acceleration and/or inclination, resulting from interaction of the oil repulsion part, connecting rod, and crankshaft cheeks. Thus, lubricant oil supply is always assured, without pumps additionally integrated into the engine, which increase costs and likelihood of failure. The oil pan may also now be flatter, which allows a low center of gravity of the engine while maintaining the required minimum road surface distance. Regarding oil change intervals, a greater amount of oil can be used, with the same proportions of the oil pan.
