INTERNAL COMBUSTION ENGINE WITH HIGH RESTRICTIVE CHARACTERISTIC AND HIGH LOAD RECEIVING SPEED Russian patent published in 2013 - IPC F02B37/07 F02B37/04 F02B37/12 F02D23/00 

FIELD: machine building.

SUBSTANCE: internal combustion engine includes two turbocompressors (2) and (3) with different adjustment, one of which (2) has a nozzle block with a larger cross section. Supply of exhaust gases to each turbocompressor (2) and (3) is performed via individual gas supply circuits (4) and (5) with connection pipeline (6). Shutoff devices (7) and (8) are installed in gas supply circuits (4) and (5). Inlet devices of compressors are combined with common branch pipe (12), from which parallel pipelines (13) and (14) with shutoff members (15) and (16) installed on them are branched. Driven supercharger (17) is installed on one pipeline (13). Gas flow controlling member (11) is installed after the turbine of turbomachine (3) with smaller cross section of nozzle block. Driven supercharger (17) located in one of parallel pipelines (13) is activated from an outside source.

EFFECT: increasing economy, power and reliability of the engine.
