FIELD: engine engineering. SUBSTANCE: plant has air compressor 20 and separator 10 for separating fuel vapors from a fuel-air mixture that is supplied from fuel tank 12. The delivery part of compressor 20 is connected with injectors 22 of the system for supplying fuel under pressure immediately to combustion chambers. The device can be provided with a fuel distributor with the fuel passageway for providing the constant circulation of fuel from fuel tank 12 to respective fuel injectors 22 and air passageway for supplying air to the injectors from compressor 20. The plant can be also provided with Venturi tube 31, device for selective shutting off the air flow from separator 10 to compressor 20, and programming facility 34 for batching fuel to determine how much fuel is necessary for the engine depending on operation condition, fuel flow rate from separator 10 to compressor 20 being corrected. EFFECT: enhanced efficiency. 8 cl, 3 dwg
