FIELD: engine building.
SUBSTANCE: lubrication system of an internal combustion engine includes an oil crankcase 1, a main oil pump 3, an oil filter 4, and a main oil line 14. The compensation oil pump 11 with an electric drive is connected to the lubrication system through a technological hole in the oil crankcase 1 and an oil channel in front of the oil filter 4. The dynamic pressure sensor 12 is installed in the main oil line 14. The compensation oil pump 11 and dynamic pressure sensor 12 are connected to microcontroller 13 configured to turn on the compensation oil pump 11 when the pressure in the main oil line 14 drops below 0.25 MPa in nominal mode at a speed of 2600 min-1.
EFFECT: prevention of emergency failures when the internal combustion engine wears out during operation.
