FIELD: mechanical engineering. SUBSTANCE: injector includes housing with fuel tube mounted in housing coaxially at circular clearance. Tube is provided with central nozzle end-piece connected to circular clearance by means of branch pipes provided in lateral wall. It is additionally provided with swirler made in form of impeller secured on nozzle end-piece. Impeller is provided with wedge-shaped blades with sharp leading edge. Atomizer may be provided with second swirler made in form of hub secured on fuel tube and provided with helical projection whose section increases in way of flow; projection has sharp leading edge. Hub of second swirler and fuel tube are provided with passages inclined towards axis. These passages bring fuel tube (before first swirler) in communication with circular clearance (after second swirler. EFFECT: intensification of fuel dispersion process.
