    Abstract: The present invention relates to the use of a composition of additives for reducing emissions of nitrogen oxides and of at least one type of pollutant selected from carbon monoxide and hydrocarbons which are unburnt during the combustion of a liquid fuel in a compression-ignition internal combustion engine, said composition comprising: (i) one or more additive(s) selected from compounds having at least one alkylphenol group in their structure; and (ii) one or more additives which improve the cetane number, selected from alkyl nitrates, aryl peroxides and alkyl peroxides; wherein the weight ratio of the amount of additive(s) (i) to the amount of additive(s) (ii) is within the range from 1:3 to 3:1. The present invention also relates to a method for reducing emissions of nitrogen oxides and of at least one type of pollutant selected from carbon monoxide and hydrocarbons which are unburnt during the combustion of a liquid fuel in a compression-ignition internal combustion engine which employs this composition of additives.

    Abstract: The invention is a fuel and a method for producing an improved hydrocarbon fuel for internal combustion engines and turbines. The method includes the steps of subjecting a conventional hydrocarbon liquid fuel to ozonization. The ozonization is performed under one of two conditions. The first of the two conditions is a process of forming a current of the liquid fuel and bubbling an ozone-oxygen mixture in a countercurrent through the liquid fuel. The second of the two conditions is a process of enriching the liquid fuel with oxygen and subjecting the enriched fuel with ultraviolet radiation. Desirable concentrations of ozonization products in the fuel are from 0.1% o to 2.0% o.
