Аннотация: A complex of technical means and methods for researching the parameters of the operation of turbocompressors of internal combustion engines of mobile energy vehicles is substantiated. The regularities of changes in the parameters of the lubrication processes of the rotor bearings of the internal combustion engine turbocompressor during the operation of the hydraulic accumulator and the simultaneous braking of the rotor by the brake device built into the intake manifold of the engine have been established.2023-01-01T00:00:00ZPLASTIC LUBRICANTS BASED ON WASTE MOTOR OILSUmynskyi S.

Аннотация: The technological process of restoration of triboconnections of power gyro cylinders with composites based on modified kaprolon is justified. Physico-mechanical, tribological and rheological characteristics of kaprolon-based composites containing fine powders of copper iodide, shungite, molybdenum disulfide, graphite and chopped carbon fiber were revealed, the technological process of power hydraulic cylinder repair using anti-friction composites was substantiated.2023-01-01T00:00:00ZENSURING INCREASE IN THE DURABILITY OF DIESEL CRANKSHAFTS BY TECHNOLOGICAL METHODSUmynskyi S.

Аннотация: The peculiarities of the wear of the necks of crankshafts are analyzed. Modification of the surface of the crankshaft neck with mineral and organo-mineral materials makes it possible to increase the wear resistance of the coupling in the entire range of heating temperatures of the lubricant, reduce the values of friction coefficients and temperature in the tribocontact zone and, accordingly, significantly increase the durability of the tribonode.2023-01-01T00:00:00Z
