Експлуатаційні випробування пристрою для електростатичної обробки моторної оливи

Abstract

UA: У статті наведено матеріали експлуатаційних випробувань удосконаленого пристрою для електростатичної обробки напівсинтетичної моторної оливи EXTRA DI 10W40 при її роботі в системі змащування дизельного двигуна Д-240 колісного трактора МТЗ-82. Наведено конструктивні особливості та технічні характеристики удосконаленого пристрою, місце його встановлення в систему змащування двигуна і підключення до бортової мережі машини. Наведено результати випробувань пристрою за критеріями впливу електростатичної обробки на окремі характеристики дизельного двигуна і трибологічні характеристики моторної оливи.

EN: The article presents the materials of operational tests of the improved device for electrostatic treatment of semi-synthetic motor oil EXTRA DI 10W-40 during their operation in the lubrication system of the diesel engine D-240 wheeled tractor MTZ-82. Since the testing of the device consisted of two stages, the main part of the article consists of two interrelated parts, which show the main results for each stage. The first part presents the design features and technical characteristics of the advanced device, as well as the place of its installation in the engine lubrication system and connection to the onboard network of the machine. Particular attention in describing the design of the device is paid to its differences from previous counterparts, namely the presence of stepwise regulation of the output voltage level and the presence of protection of the oil from electric breakdown. The second part of the article presents the test results of the device according to the criteria of the influence of electrostatic treatment on the characteristics of the diesel engine and some performance properties of engine oil. When disclosing the effect of electrostatic oil treatment on engine characteristics, the article presents data on changes in oil pressure in the main line of the lubrication system and changes in compression in the engine cylinders as the engine speed increases. When disclosing the effect of electrostatic treatment on the performance properties of engine oil, data on changes in the tribological characteristics of the oil, namely the diameter of the wear spot, with its different operating time in the engine lubrication system. The diameter of the wear spot was installed on a four-ball friction machine according to the method described in GOST 9490-75. According to this method, the values of the diameter of the wear spot for the engine oil during its operation in the engine lubrication system without the use of electrostatic treatment, as well as with the use of such treatment in the built-in device. The final part of the article presents an analysis of the results, conclusions and practical recommendations for the application of the proposed improved device in the lubrication systems of diesel engines of self-propelled vehicles.
