FIELD: engines and pumps.
SUBSTANCE: lubrication system of an internal combustion engine with a dry crankcase, comprising an oil tank, a drain pump which sections inlets are communicated with oil intakes of an engine case, an oil feed pump which inlet is communicated with the oil tank, and which outlet is connected to the main line of the engine, an oil heat exchanger, which outlet communicates with the oil tank, a drainage pipe connecting the oil tank with the crankcase, at that the system comprises an additional oil pump, and the oil tank consists of two sections communicating with each other with the possibility of free flow of excess oil from one section to another, the outlet of the drain oil pump and the inlet to the additional oil pump communicate with the first section of the oil tank, the outlet of the oil heat exchanger and the inlet to the feed oil pump are communicate with the second section of the oil tank, and the outlet of the additional oil pump communicates with the inlet of the heat exchanger.
EFFECT: improved efficiency of lubrication system of engine with dry crankcase.
