FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to the exhaust gases recirculation. Exhaust gases recirculation system for the internal combustion engine (101) comprises a number of combustion chambers (11, 12, 13, 14, 15, 16), divided into first section (130) and second section (140). At least one intake valve (21, 22, 23, 24, 25, 26) and at least one exhaust valve (31, 32, 33, 34, 44, 35, 45, 36, 46) are connected to each combustion chamber (11, 12, 13, 14, 15, 16). At least one inlet manifold (50) is fluidly communicating with the said number of combustion chambers (11, 12, 13, 14, 15, 16) by means of corresponding intake valves (21, 22, 23, 24, 25, 26). First exhaust manifold (150) is in fluid communication with the said first combustion chambers section (130) by means of corresponding exhaust valves (31, 32, 33). Second exhaust manifold (160) is in fluid communication with the said second combustion chambers section (140) by means of corresponding exhaust valves (34, 35, 36). At least one EGR exhaust valve (44, 45, 46) is connected to each combustion chamber in the said second section (140). EGR manifold (170) is in fluid communication with each combustion chamber (14, 15, 16) in the said second section (140) by means of corresponding EGR exhaust valves (44, 45, 46) and with at least one intake manifold (50). Also disclosed is the exhaust gases recirculating method in the internal combustion engine.
EFFECT: technical result is in the high-pressure exhaust gases recirculation improvement from the internal combustion engine with turbocharger.
