Embodiment Construction

[0033] Referring now to the drawings, FIG. 2 shows an oil repulsion part 1 integrated into an internal combustion engine 3. A connecting rod 2 and crankshaft cheeks 4 are disposed on the outside in the direction of the transverse acceleration and / or inclination R. The direction of the transverse acceleration relating to the present invention means the direction of the centrifugal acceleration which is directed against the centripetal acceleration. Oil repulsion part 1 is configured, in the region of connecting rod 2 and crankshaft cheeks 4 so that a centrifugal flow, resulting from the interaction of oil repulsion part 1, connecting rod 2, and crankshaft cheeks 4 is brought about. This centrifugal flow is used for transport of the lubricant oil into the region of an oil pan 6 that lies opposite the transverse acceleration and / or inclination. A lubricant oil suction system 11 is disposed in this region of oil pan 6.

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.

Description

BACKGROUND OF THE INVENTION CROSS REFERENCE TO RELATED APPLICATIONS [0001] Applicant claims priority under 35 U.S.C. §119 of German Application No. 10 2004 024 780.3 filed May 17, 2004. [0002] 1. Field of the Invention [0003] The present invention relates to a method and a device for lubricant oil transport in an internal combustion engine using wet sump lubrication. [0004] 2. The Prior Art [0005] It is known that in the case of transverse installation into a motor vehicle of an internal combustion engine using wet sump lubrication, the lubricant oil supply is problematic when severe transverse acceleration, inclination, or both occurs. The central suction system is disposed deep in the wet sump and is connected with the lubricant pump. Thus, a risk exists that the central suction system will draw air in, instead of lubricant oil, and thereby interrupt lubricant circulation. [0006] To improve the reliability of the lubricant oil supply in case of severe transverse acceleration and / o...
