FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Engine system comprises exhaust pipeline of engine and mixer (201) of exhaust gas arranged in outlet pipeline. Mixer (201) contains input and output sections (202) and (206) and middle section (204). Each inlet and outlet sections (202), (206) comprise a perforated annular wall (211), (241) inclined in the flow direction and inward, and a perforated towards flow cone (216), (250) which is vertically aligned with annular wall (211), (241). Middle section (204) is arranged between inlet and outlet sections (202) and (206). Middle section (204) comprises a perforated annular cross-section structure. Embodiment of engine system and engine exhaust pipeline are disclosed.
EFFECT: technical result is improved mixing of exhaust gases.
