FIELD: engines and pumps.
SUBSTANCE: invention relates to lubrication system control units of internal combustion engines. The method of oil pressure stabilisation for providing of start-up of internal combustion engines implemented in the engine lubrication system comprising the feed tank, the pump with injection oil line, and downstream the oil pump a pilot bypass valve is installed which is opened for oil bypass by means of control signal implemented as oil pressure fed through separate pipeline to the valve union from the cavity located just upstream bearing assemblies of the engine, in case of excess of its pre-set value.
EFFECT: invention provides control and maintaining of stable value of oil pressure upstream bearing assemblies of the engine on all modes of its operation.
