INTERNAL COMBUSTION ENGINE TURBOCHARGE SYSTEM Russian patent published in 2023 - IPC F01D25/10 F01D25/12 F01D25/14 F01D25/24 F02B39/00 F02B39/14 F02C6/12 F04D29/58 F01D25/26 F01M1/00 

FIELD: engine building.

SUBSTANCE: turbocharger system for an internal combustion engine is proposed, including main oil line 4, pressure pipeline 10 connecting line 4 with a turbocharger bearing 11, hydraulic accumulator 1 connected by an inlet channel through check valve 3 to main oil line 4. Housing 15 is additionally mounted on the turbocharger housing to form a gap between housing 15 and the turbocharger bearing housing 12. Air compressed in the turbocharger compressor enters the specified gap for accelerated heating of bearing housing 12 when starting the internal combustion engine, as well as for cooling the bearing housing during the operation of the internal combustion engine and in the idle mode of the internal combustion engine. Air channel 22 is provided, through which air from said casing 15 enters inlet pipe 25 of the turbine to cool turbine 19 in the idle mode of the internal combustion engine.

EFFECT: increase in the service life and an increase in the efficiency of an internal combustion engine equipped with a turbocharger.
