Abstract: An apparatus and a method for cavitating a mixture of a fuel and an additive are disclosed. The apparatus comprises a cavitation stream, the cavitation stream comprising a counter jet device, a jet stroke device and a swirling cavitation device. A mixture of a fuel and additive is arranged to pass through the cavitation stream, wherein the mixture undergoes wave and cavitation processing in the swirling cavitation device. The cavitation apparatus further comprises a resonance chamber and a homogenizer, into which the wave and cavitated mixture is passed to obtain an emulsion of improved homogeneity from an outlet of the homogenizer.

Abstract: The method and apparatus for making a micro-dispersed gas-liquid mixture which includes a gas-liquid ejector unit, a cavitation unit and a jet dispersing unit installed in a sequence. All above referenced units are installed into a cylindrical housing which in turn includes bottom and top covers and also has a first partition having a conical orifice separating a gas-liquid ejector unit from a cavitation unit and a second partition separating a cavitation unit from a jet dispersing unit. The gas-liquid ejector unit has an inlet located at the bottom of the cylindrical housing for liquid and the inlet located on side surface of housing for gas, these being between bottom cover of the housing and the first partition. In addition, the inlet for liquid is a nozzle the top having both outside and inside parts of which are adapted to the conical orifice of first partition to provide a required flow-rate of an ejected gas through the gas inlet.
