FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Exhaust gas mixer (200) comprises first cylindrical tubes (220), second cylindrical tubes (230) and outer tube (210). First cylindrical tubes (220) are located at the distance from central axis (295) of the exhaust pipe. Each of first tubes (220) has holes (226) facing radially outward from central axis (295). Second cylindrical tubes (230) are located at the distance from central axis (295) and first tubes (220). Second tubes (230) are located downstream of first tubes (220) and with angular displacement relative to them. External pipe (210) is connected to outer surface of exhaust pipe. First tubes (220), second tubes (230) and outer tube (210) are symmetrical about central axis (295). Invention covers versions of exhaust gas mixer.
EFFECT: technical result consists in improvement of mixing.
