<p>Additives for heating and motor fuels contg. (A) a condensn. prod. of 1 mol glycerol or 1 mol polyethanolamine and 1-2 mols fatty acid with at least 10C atoms, (B) an ester of a sat. cycloaliphatic alcohol with 5-7 ring atoms and a lower fatty acid, and (C) one or more mineral oil raffinates with viscosity 1.6 degrees E min. at 20 degrees C and 15 degrees E max. at 50 degrees C. Use of (B) as the solvent component in fuel additives in general is also claimed. Combustion of diesel oil is intensified and improved. Residues e.g. soot, in the injection nozzles and outlets are reduced and broken down. Content of soot, unburnt hydrocarbons, etc. in the exhaust gases is reduced. Wear on the injection assembly, piston rings, etc. is reduced, parts in contact with fuel are protected from corrosion and the ageing stability of diesel fuel is improved.</p> |
