METHOD OF EXHAUST GASES RECIRCULATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC F02M25/06 

FIELD: engines and pumps.

SUBSTANCE: invention refers namely to thermal engines with combustion products recirculation. Method of exhaust gases (EG) recirculation consists in the fact that EG are sent tangentially to the inner surface of cylindrical case with the possibility of movement in a form of swirled air, the air is sucked from the atmosphere through the pipe ensured by the negative pressure in the intermediate part of swirled air, the pipe is installed coaxially the inner surface of the case. The air is mixed with the part of EG to form cooled flow that is supplied to the recirculation, and the air sucked from the atmosphere is formed by screw-line. Note that along the pipe axis there installed is swirler that is charged by positive charge, and pipe case is charged by negative charge. There provided is the structure of device for EG recirculation.

EFFECT: such design allows reduction of fuel consumption and exhaust emissions at all engine operating modes.
