SUPERCHARHING AIR COOLING CIRCULATION CIRCUIT ARRANGEMENT AND METHOD OF OPERATION OF CIRCUIT OF SUCH ARRANGEMENT

FIELD: engines and pumps. ^ SUBSTANCE: invention relates to the arrangement of the circuit (C) of circulation with low-temperature circuit (LTC) of circulation for cooling supercharging air (13) fed into engine (8) of a vehicle with a supercharger. Here a two-stage compression of supercharging air (13) in first low-pressure turbo supercharger (1) and in second high-pressure turbo supercharger (2) is effected. To cool down supercharging air (13) downstream of low-pressure turbo supercharger (1) and upstream of high-pressure turbo supercharger (2), first radiator (3) is provided, while downstream of high-pressure turbo supercharger (2) and upstream of engine (8) second radiator (4) is provided. In low-temperature circuit (LTC) of circulation low-temperature radiator is arranged for low-temperature cooling medium (14) to pass the said radiator after it passed through radiator (3) being cooled by cooling medium, both radiators being used for low-pressure supercharging air. ^ EFFECT: improved arrangement of circulation circuit. ^ 11 cl, 4 dwg
