GAS MIXER Russian patent published in 2022 - IPC F02M21/04 F02M26/17 F02M26/19 

FIELD: gas mixers.

SUBSTANCE: gas mixer containing a body (1) of the mixer and a core (2) of the mixer. The core (2) of the mixer contains the core (21) for fuel gas and the main part (22) for EGR; the fuel gas core (21) is provided internally with two fuel gas injection pipes (3) that intersect, and four EGR injection pipes (4, 5) are provided in the EGR main body (22) and form a crossed core for EGR mixing in Swiss cross shape. The fuel gas mixing core structure and the gas mixer EGR mixing core structure, both are designed as an intersecting joint formation in the shape of a Swiss cross, so that fuel gas and exhaust EGR can be ejected from a plurality of injection holes of the radial injection pipe and fill the cross section of the core (2) mixer, which further improves the homogeneity of the fuel gas and exhaust EGR entering the mixer core and combines relatively low pressure loss with relatively high operational reliability.

EFFECT: sensitivity of the mixing effect of the mixer to the downstream guiding pipelines is reduced.
