Investigation of motor oil additive detergency under electric field conditions

Abstract

1. It has been established that an emf of about 1 V is set up between two dissimilar metals separated by a layer of motor oil; with normal clearances between internal combustion engine parts, this will create an electric field intensity of up to several thousand volts per centimeter. 2. A method has been developed for recording automatically the process of washing deposits of radioactive disperse phase from a metal surface by detergent motor oil additives under the influence of an electric field. 3. It has been shown that those additives which give high electrical conductivity in motor oil solutions are capable not only of preventing the formation of deposits of disperse phase on the electrodes under electrical field conditions, but also of washing off preformed deposits.
