    摘要: The invention relates to fuel compositions containing over 50% percent by weight diesel, gasoline, kerosene, or other hydrocarbons which are liquid at room temperature. The invention is characterized in that the compositions contain 0.001 to 0.1 percent by weight of an additive of formula (I), wherein R represents a monounsaturated or polyunsaturated alkylene radical with 17 C atoms, n is 2 or 3 and k represents a number between 0.5 and 3, with the proviso that the sulfur content in the fuel composition docs not exceed a maximum of 0.2 percent by weight.

    摘要: Procedure to generate biodiesel fuels with improved properties at low temperature by the transesterification of triglycerides with alcohols such as methanol or ethanol, optionally in the presence of methyl or ethyl acetates of fatty acids and an inert solvent, to produce methyl or ethyl esters of fatty acids, glycerine and, where appropriate, glycerine triacetate, followed by the separation of crude glycerine that is reacted with aldehydes, ketones and/or acetic acid or methyl or ethyl acetates to produce acetals, glycerine cetals and/or glycerine acetates. The acetals, glycerine cetals and/or glycerine acetates are mixed with methyl or ethyl esters of fatty acids in concentrations of approximately 0.5-20% by weight to obtain a biodiesel with improved properties at low temperatures.

    摘要: The present invention is directed to a composition for use in a combustion engine either as a fuel additive or as an additive for a crankcase lubricant. The composition may include a polyunsaturated aliphatic or alicyclic compound having at least three, but no more than six, double bonds to improve the combustion process by acting as pseudo-catalyst in the combustion reaction. The composition may further include a derivative of dihydrobenzo-gamma-pyrane to improve the combustion process by acting as pseudo-catalyst in the combustion reaction. The composition may further include surfactants such as polyethylene glycol and/or one or more polyoxyalkene derivatives of either polypropylene glycol, polyethylene glycol or sorbitol. A media of fatty acid esters is provided to dilute the combustion promoters, surfactants and other ingredients allowing accurate concentrations of these ingredients to be introduced into the fuel chamber.
