car engine, crankshaft bearings, lubrication mode, tribological parameter, speed and load characteristicsAbstract
The article discusses the dynamics of the lubrication process during the operational wear of the crankshaft bearings of automobile engines. All lubrication modes and wear processes are analyzed. The main attention is paid to the steady and unsteady modes of lubrication of the crankshaft bearings. The nature of the dynamics of changing lubrication regimes is substantiated through operational tribological parameters that characterize the integral degree of existence of the lubricating layer. A model is proposed for the relationship of these parameters with a number of factors, and the nature of their changes with a change in the speed of the crankshaft of the car engine is substantiated.
The results of bench tests of diesel engines of the KamAZ series, speed and load characteristics of the engine in terms of tribological operational parameters are presented. A graphical interpretation of the tribological parameter in the field of the load-speed mode of KamAZ engines is given
