Abstract

Topical aspects of assessing the effect of crankcase gases of an internal combustion engine on the operational properties of engine oil taking into account its service life are considered. For a mathematical description of the change in the condition of engine oil, a complex criterion for assessing oil operational properties and a criterion for assessing the saturation with crankcase gases are proposed. At the same time, it has been found that the change in each of the criteria depending on the service life and engine rotational speed can be approximated by an exponent at a confidence level amounting to 0.95. The parameters of the proposed criteria have been assessed. It is shown that these criteria can be used jointly for diagnosing the condition of engine oil. It has been established preliminarily that the detailed service life of the engine affected by the properties of engine oil can be determined by the simulated time of interaction between the oil and the crankcase gases.

曲轴箱气体和发动机油之间相互作用的评估

摘要

考虑到发动机油的使用寿命,评估内燃机曲轴箱气体对发动机油运行特性的影响的局部方面。对于发动机油状态变化的数学描述,提出了用于评估油运行特性的复杂标准和用于评估曲轴箱气体饱和度的标准。同时,已经发现取决于使用寿命和发动机转速的每个标准的变化可以在总计为0.95的置信水平下通过指数近似。已对拟议标准的参数进行了评估。结果表明,这些标准可以共同用于诊断发动机油的状况。
