Autotractor engine durability increase due to using tribopreparations
The studies of the country’s leading institutions found the life of the repaired engines to be 3... 5 times lower than the normative one. One of the ways to improve the post-repair durability and reliability of diesel engines at the existing level of repair quality is the introduction of special tribo preparations in lubricants both during the operational break-in and during the regular operation. In Russia and abroad, more than 200 different tribotechnical preparations of different brands are produced, and it becomes necessary to develop a method for choosing rational tribomaterials to improve the durability and reliability of the engine after repair. The main criteria for the selection of a rational tribopreparation are for the operational post-repair run-in of the internal combustion engine - guaranteed elimination of scoring, and to increase the durability - the minimum wear rate of parts in the resource interfaces in the regular operation mode. Taking into account the foregoing, the method of choosing a rational tribopreparation for ICE is presented due to which the life of engines can be increased by 2-3 times due to the choice of a rational preparation in the composition of motor oil
