Research ArticleOpen accessMarine Slow-Speed Diesel Engine Diagnosis with View to Cylinder Oil SpecificationSergey Victorovich Sagin, Oleksandr Vladymyrovich SemenovThe possibility of marine slow-speed diesel engine cylinder-piston group diagnosis with view to the specification of waste oil taken from the under-piston space has been discussed. The specifics of using high-base cylinder oils in marine slow-speed diesel engines to prevent sulfur corrosion of the cylinders have been described. Typical challenges, arising in the process of using oils for lubricating the … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 25 May 2016 · 7,812 accessesView PDF Cite

Research ArticleOpen accessMotor Oil Viscosity Stratification in Friction Units of Marine Diesel MotorsSergey Viktorovich Sagin, Oleksandr Vladymyrovich SemenovThe phenomenon of the motor oil viscosity stratification in lubricating the cylinder-piston units of marine diesel engines has been investigated. The correlations for determining the shear stress and the velocity, occurring in the liquid flow between the parallel planes, have been given. The modes of the hydrodynamic and the boundary lubrication, taking place in the cylinder assembly of the marine … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 15 Feb 2016 · 8,011 accessesView PDF Cite
