METHOD OF ACTUATION OF SUPERCHARGED ENGINE (VERSIONS) AND ENGINE SYSTEM Russian patent published in 2016 - IPC F02B33/44 F02M26/04 

FIELD: motor vehicle industry.

SUBSTANCE: invention relates to machine building, namely, to automotive industry. System (100) of engine (10) includes cylinder (14) of engine (10), nozzle (166) of direct injection designed for direct injection of some amount of fuel into cylinder (14). First inlet channel (42) is connected to interact with first outlet channel (46), herewith first inlet channel (42) includes first inlet valve (84) to supply some amount of recycled exhaust gases into cylinder (14). Second separate inlet channel (44) is connected to interact with second separate outlet channel (48). Herewith second inlet channel (44) includes the second inlet valve to supply some amount of fresh compressed air into cylinder (14). Compressor (52) of turbocharger is connected to second inlet channel (44), herewith compressor (52) is driven by turbine (54) attached to second outlet channel (48). Actuator (96) of the valve is made with the possibility of opening the first inlet valve with the first setting of the inlet valve distribution phases, and the second valve with the second different inlet valve distribution phases. Also disclosed are versions of the method of actuation of the supercharged engine.

EFFECT: technical result is higher thermal efficiency of a turbocharged engine.
