FUEL EVAPORATION DEVICE Russian patent published in 2021 - IPC F02M29/02 F02M31/125 F02M31/18 

FIELD: fuel production.

SUBSTANCE: present invention relates to devices for preparing fuel-air mixtures for internal combustion engines and can be used in engines of vehicles, power plants, chainsaws and other devices. A device for evaporation fuel containing a housing 1 with windows 2 for air intake, located in the housing 1 of the electric heater 3, connected to the fuel supply channel 4 on one side and the nozzle sprayer 5 on the other, and a swirler 6 is installed in the lower part. The windows 2 in the housing 1 are in the form of trapezoids, the large bases of which are placed from below, the nozzle sprayer 5 contains three rows of circular holes 7, the diameter of which decreases in rows from the upper row to the lower, and the swirler 6 located in the lower part has blades 8, 9 with different angles of inclination to the longitudinal axis of the housing 1, which alternate in the circumferential direction, the electric heater 3 is placed in a hollow cylindrical casing 10, which has a nozzle 11 installed tangentially to its side surface, which is attached to the fuel supply channel 4.

EFFECT: proposed device for fuel evaporation makes it possible to improve the quality of the prepared fuel-air mixture, increase the power and improve the economic performance of the engine.
