Abstract
The present invention relates to an additive for a fuel for the neutralization of SO,and/or SO,in the exhaust gases of internal combustion engines operated with the fuel, and a method for the neutralization of SO,and/or SO,in the exhaust gases of internal combustion engines. According to the invention, the additive contains one or more metal compounds soluble in the fuel. In the combustion of the fuel these compounds form stable sulfates which are present in solid particles in the exhaust gas. The method of the invention is characterized in that one or more of these additives are added to the fuel and the combustion of the fuel takes place in an oxidizing atmosphere.
