A mehtod for mixing water and diesel fuel in a ratio between 5 and 20 Vol %, in which the liquid components are recirculated in a recirculation loop comprising an ellipsoidal vortex chamber (10) in which rotation around a longitudinal axis (9) is attained, the rotating fluid is expanded and tangentially injected in a baloon-like second vortex chamber (16) with an axis (17) normal to that of the first chamber, the open lower end of the second rotational chamber (16) is connected to fluid inlets and suction side of a recirculating pump. The outlet occurs from the equatorial plane of the second vortex chamber. The outflow rate should be at least ten times less than the flow in the recirculation loop. The mixture which have water droplets smaller than 200 nm has a consistency similar to that of fuel and can be used as fuel to diesel engines, whereby the amount of unwanted components in the exhaust gases will be reduced.

A method for mixing diesel fuel with water to obtain a combustible emulsion, in which the amount of water to fuel falls in a range of 5 to 20 Vol %, in which the fuel and the water are injected in a closed space in a ratio falling in said range and are intensively moved, characterized in that said injected components are intensively recirculated in a closed loop, in each loop a first vortex is formed, in the first vortex the circulating fluid is forced to rotate around and moved along an axis (9) of a first vortex chamber (10) so that the pressure is increased along the axial movement, the pressure of the rotating fluid is suddenly decreased by a predetermined amount when leaving the first vortex chamber (10) then is gradually increased in a tapering passage duct (24) while the rotation is maintained, the fluid rotating around the axis of movement is passed tangentially in a second vortex chamber (16) to form a second vortex around a second axis (17) substantially normal to the axis of rotation of the inflowing fluid, the fluid is rotated around and passed along the second axis (17) and the fluid leaving the second vortex chamber (16) is pumped and recirculated again in the first vortex chamber (10), a portion of the recirculated fluid is lead out of the loop in such a stream that in average the fluid particles participate at least in ten full cycles before they would leave the loop.
