Abstract
An internal-combustion engine having a pressure lubrication system according to the dry-sump principle, particularly for an opposed-cylinder engine, having a crankcase in which an oil scavenging space is constructed in the lower part feeds the lubricating oil by way of an oil return feed pump equipped with an oil scavenging pipe to an oil storage tank. The lubricating oil situated in the oil storage tank is fed by way of a main feed pump to the consuming devices. The oil storage space forming the wet sump is also integrated in the crankcase of the internal-combustion engine.
