In view of the increased dynamic and temperature load in the compression-ignition engine tribological systems, particular attention is drawn to the problem of such lubrication of the friction nodes that after breaking the boundary layer it could be restored without any wear occurring. Therefore, an idea has been devised of introducing to friction nodes, with the lubrication oils, of new substances (operational preparations) modifying the surface layer of friction elements, creating the so called servo-films as an effect of selective transfer at the extreme loads. The paper presents a method of evaluation, by means of the acoustic emission (AE) symptom, of a lubricating oil, without operational preparations, through creation of the servo-film.
