METHOD FOR TURBOCHARGING INTERNAL-COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: thermal engineering. SUBSTANCE: method involves compression of atmospheric air in turbocompressor, its cooling down by means of low-temperature cooler using intermediate coolant which is, essentially, low-boiling liquified gas circulating over closed intermediate loop between two regenerating porous compact heat exchangers; supercharging air is forced through one of them being cooled down by intermediate coolant; atmospheric air is forced through other heat exchanger to cool down intermediate coolant in it. EFFECT: provision for turbocharging internal-combustion engine at ambient temperature fluctuations between -50 and +50 C. 1 dwg, 1 tbl
