<p>Method and apparatus for producing a water-in-fuel-emulsion and emulsifier-free water-in-fuel-emulsion. The apparatus for generating a fuel water emulsion for the operation of an injection pump, particularly that of a diesel motor, comprising a rotationally symmetric vortex chamber (1) with a tangential inlet and a tapering axial outlet. In order to generate a fine homogeneous emulsion in colloidal state, having a size of the suspended water droplets of 1000 nm or less, the axial end portion of the vortex chamber (1) facing away from the outlet is surrounded by a ring channel (7) running coaxially to the vortex chamber (1), the ring channel (7) being connected to the vortex chamber (1) via inlet slots (9) which are tangentially aligned to it and in which a fuel inlet channel (8) tangentially ends. An electromagnetically controlled water injection nozzle (10) leads into the end portion of the vortex chamber (1) at the inlet side thereof. The outlet (2) of the vortex chamber (1) opens via an enlargement (3) into a suction chamber (4) of a radial wheel (5) which is arranged in a pump chamber (12) having an outlet channel (13) in the area of the circumference of the radial wheel (5) to which a forward conduit leading to the injection pump and a recirculation conduit leading to an emulsion inlet channel (15) are connectable which also ends tangentially into the ring channel (7). An intake channel (16), to which a return conduit coming from the injection pump is connectable, leads into the suction chamber (4) of the radial wheel (5).</p> |
