<p>Additive for unleaded Otto fuel is based on alkali metal salts of alkylnaphthalene sulphonic acids, optionally in mixture with detergents and additives known as fuel additives. The novelty is that the K-salt of a dialkylated naphthalene sulphonic salt is used having linear 8-14C alkyl chains to produce simultaneous emulsifying, wear protection and corrosion protection action. Also claimed is the Otto fuel itself containing 2.3-40 mg K.</p> |
