<p>Aqueous-base compositions are disclosed for the lubrication of the piston and the cylinder liner of Diesel engines, particularly large engines, said compositions essentially comprising one or more water soluble anti-acid neutralizers, a water soluble organic fluid having a high boiling point temperature and one or more water-soluble detergents. Tests on large engines have shown that it is possible to lubricate the piston and the cylinder liner with an aqueous base fluid without using any crude petroleum derivative.</p> |
