INTERNAL COMBUSTION ENGINE TURBOCOMPRESSOR INDEPENDENT LUBRICATION SYSTEM Russian patent published in 2024 - IPC F02B39/14 F01M1/02 F01M1/12 F01M1/22 F01M1/24 F01M1/28 

FIELD: machine building.

SUBSTANCE: invention relates to lubrication systems and is intended for lubrication of turbocompressor of internal combustion engine (ICE). Disclosed is a self-contained system of lubrication of a turbocompressor ICE, which includes oil line 1 made in the form of a closed circuit and containing oil pump 4, oil filter 9 and a lubricating oil tank 8. Oil line 1 comprises hydraulic accumulator 10, oil pressure indicators 12 located between oil filter 9 and check valve 11 and between hydraulic accumulator 10 and bearing assembly 2 of turbocompressor. Oil pump 4 is equipped with bypass valve 7, is fixed separately from ICE and is driven by self-contained electric motor supplied from vehicle on-board network. Fuel cutoff safety valve 17 is connected to oil line upstream of check valve 11 and hydraulic accumulator 12, through which ICE is supplied with fuel.

EFFECT: higher reliability of turbo compressor operation, lubrication of friction surfaces of turbo compressor parts before ICE start, during ICE operation in different modes, at voltage fluctuation in onboard electric system and at emergency stop of ICE.
