Engine Lubrication Oil Aeration
The lubrication system of an internal combustion engine serves many purposes. It lubricates moving parts, cools the engine, removes impurities, supports loads, and minimizes friction. The entrapment of air in the lubricating oil is called oil aeration. Oil aeration can be detrimental to internal combustion (IC) engines. This study attempts to determine a means to reduce the level of aeration in...
متن کاملCanola-based Motor Oils
MOTOR OILS Motor oils have been utilized since the development of steam engines as a buffer between moving and static engine components. The basic jobs of the lubricant are to prevent metal-to-metal contact and to transfer heat from friction away from the contact point. During the time of steam power, one of the best lubricants available was derived from rapeseed oil. With the development of in...
متن کاملEffects of Surface Irregularities on Piston Ring- Cylinder Tribo Pair of a Two Stroke Motor Engine in Hydrodynamic Lubrication
Tribological parameters such as friction, lubrication and wear influence strongly the engine component's life. In this study, a piston ring-cylinder system simulated taking into account the surface modifications under fully flooded lubrication and normal engine conditions. The hydrodynamic pressure field solved based on the Navier Stokes equations by Fluid Structure Interaction analysis. A real...
متن کاملA New Approach to Flow Network Analysis of an Engine Lubrication System
In order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. In this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. Two elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-d...
متن کاملViscosity Index Improver for Engine Oils: An Experimental Study
Engine oils are widely used for lubrication purposes in automobile and related industries. Viscosity Index (VI) improver has found its largest commercial applications as additives to engine oils. Examples are power steering fluid, aircraft piston engine oils, modern internal-combustion engines, turbine engine oils (stationary and aircraft), and industrial gear oils. Viscosity Index improvers ar...
