power engineering; automotive industry. SUBSTANCE: to increased intensity of burning and prevent coking in capillary structure of evaporating member and consequently, improved reliability and power of burner device equal number of symmetrically arranged longitudinal radial holes are made on side surface of air nozzle. Holes are arranged in two rows spaced in height on nozzle surface. Each hole of upper row is located on line equispaced from two near holes of lower row. Vortex flow shaper is used additionally. It is arranged between air feed nozzle and evaporating capillary structure which has axially symmetric surface with longitudinal holes. Holes on vortex flow shaper are displaced relative to holes on air feed nozzle through 1/2 of angle formed by two near holes of nozzle, and section of surface of vortex flow shaper between the holes has radius of curvature smaller than distance from axis of air feed nozzle to nearest element of surface of vortex flow shaper. EFFECT: improved reliability and power of burner. 3 cl, 5 dwg
