DEVICE FOR FEEDING AND MIXING ALTERNATIVE FUEL WITH AIR BEFORE FEEDING IT INTO THE ENGINE CYLINDERS Russian patent published in 2022 - IPC F02M21/04 

FIELD: fuel supply systems.

SUBSTANCE: invention can be used in gaseous fuel supply systems for internal combustion engines (ICE). A device is proposed for feeding and mixing alternative fuel with air before it is fed to the engine cylinders. The device includes an air supply line (1), a channel (2) for supplying alternative fuel, a cavity (3) for vaporizing alternative fuel and mixing with air. Mixing cavity has an even number of rows of alternative fuel inlets, at least two rows, and in one row the inlets (6) are made at an angle of 15-45 degrees from the tangential direction with respect to the inner diameter of the pipeline, and inlets (7) in the row following the first row are also at an angle of 15-45 degrees, but in a different direction, and further downstream there are perforated rectifying grid (4) and the pipeline (5) of homogenous mixture of gas with air.

EFFECT: increasing the uniformity of air and alternative fuel mixture concentration and reducing the loss of full pressure in the air supply line.
