Abstract

The invention relates to chemistry and in particular to technology for processing hydrocarbon fuel, including engine fuel. The invention makes it possible to obtain a fuel with high cetane and octane numbers by means of the following: the initial fuel supply occurs simultaneously with ejection; an ozone containing gas is fed into the ejection area; turbulent flows are created by displacement of such a mixture; the transformed mixture is directed into a volume with a stable pressure level; and thermodynamic equalization of the mixture parameters is achieved. During thermodynamic equalization, sprayed water is injected into said mixture. The inventive process is implemented by means of devices provided with an ejector, whereby said ejector has a suction pipe connected to an ozone generator, an input connected to initial fuel supply source and an output connected to an apparatus for the enrichment and transformation of fuel, whereby said apparatus comprises serially connected flow-through cylindrical chambers, between which an electrohydrodynamic flow converter is located, and one or two chambers for thermodynamic equalization. In such a case, the device is provided with a spray water supply source and with an electrohydrodynamic separator.
