As a result of the intensive growth of the park of internal combustion engines, as well as increasing attention to the factors of economic and ecological nature before the national economy, the task of saving and rational use of fuel and energy, raw materials and other material resources is becoming increasingly urgent. One of the ways to increase the level of agricultural production with motor oils is to reuse them after restoring some of the qualitative indicators that deteriorated as a result of their use in storage and operation. Reuse of oils can increase the period of their service, reduce irreparable losses and reduce the shortage of oil deliveries to the farm. In order to improve the quality of the intermediate cleaning of oil and the possibility of its application for a direct purpose, it is necessary to develop advanced technologies and technical means that would allow cleaning of the oil to the level of fresh commercial oils in the conditions of agricultural enterprises of different levels. It is known that contamination of oils occurs both as a result of external action, and as a result of changes in the carbohydrate composition of oils. These processes begin already at the production of oil at refineries and continue at all stages of its transportation, storage and operation. They can be classified into two main types: manufacturing and operating. Studies show that used diesel oils can contain up to 0.14% (by mass) of pollution, while autotractor oils in the same conditions - up to 0.28% (by mass), used in the operation of agricultural machinery. Analysis of existing lubricant contamination, methods and equipment for cleaning lubricants of automotive traction engines. The design of the device for oil purification and recovery is proposed.
