OPERATING TESTS OF THE DEVICE FOR ELECTROSTATIC ENGINE OIL TREATMENT

Abstract

The article presents the materials of operational tests of the improved device forelectrostatic treatment of semi-synthetic motor oil EXTRA DI 10W-40 during their operation in thelubrication system of the diesel engine D-240 wheeled tractor MTZ-82. Since the testing of the deviceconsisted of two stages, the main part of the article consists of two interrelated parts, which show themain results for each stage. The first part presents the design features and technical characteristicsof the advanced device, as well as the place of its installation in the engine lubrication system andconnection to the onboard network of the machine. Particular attention in describing the design ofthe device is paid to its differences from previous counterparts, namely the presence of stepwiseregulation of the output voltage level and the presence of protection of the oil from electricbreakdown. The second part of the article presents the test results of the device according to thecriteria of the influence of electrostatic treatment on the characteristics of the diesel engine and someperformance properties of engine oil. When disclosing the effect of electrostatic oil treatment onengine characteristics, the article presents data on changes in oil pressure in the main line of thelubrication 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, dataon changes in the tribological characteristics of the oil, namely the diameter of the wear spot, withits different operating time in the engine lubrication system. The diameter of the wear spot wasinstalled 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 itsoperation in the engine lubrication system without the use of electrostatic treatment, as well as withthe 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 improveddevice in the lubrication systems of diesel engines of self-propelled vehicles.
