摘要： The present invention relates to the engine-building industry and can find application in the fuel feed system of internal combustion engines for preconditioning part of the flow of a rich fuel-air mixture fed to the main flow to decompose liquid fuel and convert it into a gas. A technical aim of the present invention consists in an increased fuel economy of the engine, reduced toxicity of exhaust gases, and use of a cheaper low-octane fuel. A method for preparing fuel-air mixture consists in that the flow of an overrich fuel-air mixture is additionally heated, before mixing it with the other flow of fuel-air mixture, by passing it through a promoter heated above the mixture ignition temperature, thus providing repeated contact of the flow with the promoter surface. A device comprises a heat-exchanger 1 communicating, via an intake piping 3, with the engine exhaust manifold, a proportioner 5 of the components of the fuel-air mixture being handled provided with an air piping 6, an exhaust gas piping 7, and a fuel piping 8. The proportioner 5 communicates, via a control member 10 and a mixing nozzle 9, with the inlet mixture-handling loop of the heat-exchanger 1. A promoter 12 is provided in the heat-exchanger outlet nozzle, arranged in a spaceless relation thereto and being in fact a heating element having a well-developed surface and may be variously embodied.
