EJECTION-TYPE CHARGE AIR THERMAL CONTROL DEVICE Russian patent published in 2023 - IPC F02B37/00 F02M31/04 F02M31/20 F02B29/04 

FIELD: engine building.

SUBSTANCE: invention relates namely to air supply systems for piston internal combustion engines (ICEs). An ejection-type charge air thermal control device for piston internal combustion engine 1 with intake and exhaust manifolds containing gas turbine 2, compressor 3, charge air heat exchanger 4, temperature sensor 5 and control device 6 controlled by electronic control unit (ECU) 7, vortex ejector 10, communicating through pipelines with gas turbine 2 and charge air heat exchanger 4. The device includes vortex tube 9 and straight-jet ejector 8, connected by pipelines on one side to control device 6, on the other side to charge air heat exchanger 4. Control device 6 is controlled by ECU 7 and is configured to direct the flow of engine exhaust gases into vortex ejector 10 or into vortex tube 9 or into straight jet ejector 8 depending on the engine operating mode and charge air temperature.

EFFECT: increasing the efficiency of charge air temperature regulation by ensuring its heating and the use of various types of ejectors.
