THROTTLING DEVICE SYSTEM TO CONTROL AND/OR ADJUST ENGINE BRAKING MODE OF INTERNAL COMBUSTION ENGINE Russian patent published in 2017 - IPC F02B37/22 F02B37/24 F02D23/00 F02C6/12 F01D17/12 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in cars supercharged internal combustion engines throttling devices systems. Throttling device system is intended to control and/or adjust engine braking mode for engine equipped with turbo compressor. Operating on waste gases turbo compressor comprises, at least, one single- or multipath turbine (1), operating on waste gases. In turbine (1) housing (2), at least, one inlet channel (2b) is made. In inlet channel (2b) upstream of arranged in turbine impeller (3) intake chamber (7), as well as adjacent to it throttling device (8) is integrated. Throttling device (8) is located in impeller intake chamber (7) inlet channel (2b) mouth area so, that throttling device (8) in its closed position completely closed, at least, one inlet channel (2b) and thus closed hydraulic connection with impeller intake chamber (7). Inlet channel (2b) in mouth area has smaller channel cross-section, then in upstream located turbine inlet (2a) area. Invention discloses turbine compressor operating on waste gases for vehicle internal combustion engine and method of throttling device system operating.

EFFECT: technical result consists in increase of engine braking capacity in low speed range.
