FIELD: engines and pumps.
SUBSTANCE: invention relates to lubrication system (4) for internal combustion engine (2), this lubrication system (4) comprising a plurality of components comprising crankcase (20) oil pump (22) configured to supply the engine oil from oil pan (20) to lubrication system (4), cooling device (24) for cooling engine oil, oil filter (26) for filtering engine oil, and main oil line (40), intended to move engine oil in lubrication system (4) to the moving parts of the system and internal combustion engine (2). Each of the components comprises a contact surface configured to be in contact with the engine oil, and at least one of the components comprises surface-modified contact surface (200) which contains an ion exchanger which is immobilized on the contact surface. invention relates to internal combustion engine containing lubrication system, vehicle comprising internal combustion engine, and method for removing hydrogen ions from motor oil intended for lubrication system.
EFFECT: invention provides an increase in the efficiency of ion exchange in the engine lubrication system.
