Resource dependency engine oil level in the crankcase
For reliable operation of the power unit, it is necessary to ensure the required amount of oil and pressure in the lubrication system. With a decrease in the oil level in the crankcase of the engine, in addition to increasing the oil temperature, the probability of interruption of its feeding into the system and the formation of boundary lubrication conditions in friction pairs increases. When the level (volume) of the oil in the crankcase rises above Vmax, the mode of oil supply to friction pairs begins to change, which manifests itself in the foaming of an increasing volume of oil. Owing to the increase in the foaming capacity of the oil, the laminar regime of its introduction to friction pairs is violated. This causes a corresponding increase in the intensity of the change in the technical state of the engine. The solutions proposed in the work allow us to establish the optimal regime for topping up the oil.
