The device consists of a rotor (4) which is arranged in a suction pipe (1) and rotatably supported. The rotor (4) includes a hollow jacket body (5) on the outer wall of which vanes (2, 3) are arranged. A nozzle holder (26) is guided through the end (10) of the jacket body (5) directed against the air stream, which holder bears the injection nozzle (9) and is connected at the rear end with the fuel feed line (8). The fuel jets (24, 25) coming out of the injection nozzle (9) are directed against the inner wall (20) of the jacket body (5). This forms, at the same time, the jacket surface of the core hollow space (6) which widens toward the open end (11) of the jacket body (5). At the open end (11) is a centrifuge ring (14) with a spray edge (23). The rotor (4) is set in rotation by the stream of air flowing in the direction of the arrows (30, 31), and mixes the fuel centrifuged from the spray edge (23) homogeneously with the air. A measuring probe (28) determines the rpm of the rotor (4) and controls the influx of fuel through a pump to the fuel feed line (8) and thus to the injection nozzle (9).
Mix-improving device for internal combustion engines with central injection, and with a flywheel arranged in a suction pipe and set in rotation by the suction air stream, which drives a rotor with an injection device for the fuel, and is connected with the latter and a fuel feed line guided in a hollow space of the rotor, with the distinction that the rotor (4) consists of a jacket body (5) with a free core hollow space (6) and a centrifuge ring (14) which, in the flow direction of the stream of suction air, adjoins directly the end (11) of the free core hollow space (6), the jacket surface (20) diverges in the flow direction (30) of the stream of suction air, the core hollow space (6) of the jacket body (5) is at least partly closed opposite the flow direction (30) of the stream of suction air, the fuel feed line (8) is introduced at the closed end (10) of the core hollow space (6) and is connected with an injection nozzle (9), the injection nozzle (9) is arranged in the zone of the longitudinal axis (7) of the free core hollow space (6), and the spray jets (24, 25) are directed against the diverging jacket surface (20) of the core hollow space (6).
