文摘

The laboratory studies on the strength of oil were carried out by stretching it in the bellows and identified the opportunity of the strength index usage as a complex and diagnostic factor. The burst pressure and tensile modulus are used as a measure of strength. The authors study the ratio of burst pressure and the physical properties (viscosity, density, mass fraction of solids, acidity, flash point, etc.) of engine oils. The correlation with high reliability for the viscosity and the flash point is detected. This fact expands the opportunities of modeling oil viscosity and hydrodynamic cavitation.
