TURBOCHARGING SYSTEM OF INTERNAL COMBUSTION ENGINE WITH TWO DEGREES OF CONTROLLED SUPERCHARGING Russian patent published in 2016 - IPC F02B37/02 F02B37/16 F02D23/00 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engines. Turbocharging system of internal combustion engine comprises turbo compressor (1), connected through air discharge line (2) and cooler (3) of supercharging air to inlet receiver (4) of engine (5). There is bypass line (25) for portion of air compressed in compressor. Turbine (7) through diffuser (12), gas receiving branch pipe (6) and gas pipeline (8) is connected to outlet header (24) of engine (5). System includes accumulator-receiver (17) with pressure accumulator made up of cylinder with spring-loaded piston, bypass valve (14) and electronic control unit (15). Turbo-compressor includes motor-generator (19). Bypass line (25) connects accumulator receiver (17) with backspin wheels (18) with blades installed on shaft of turbo-compressor (1) on which there is anchor of electric motor-generator (19) is further installed. Air discharge line (2) of compressor, via bypass valve (14) is connected with pressure accumulator storage cavity (17). Control of bypass valve (14) and motor-generator (19), is performed by electronic control unit (15). To electronic unit (15) of sensors (16), (20), (23) of air pressure are connected, installed in air discharge manifold (2), pressure accumulator and volute turbine, as well as sensor (21) of engine crankshaft rotation frequency.

EFFECT: technical result consists in stabilisation of pressure in inlet receiver, smoothing of air shock waves and wider range of effective operation of turbo-compressor.
