| 500 ## - GENERAL NOTE | |
| General note | Advancements in engine design have necessitated use of synthetic, multi-grade engine<br/>lubricants to reduce engine friction and wear and enhance its operational life. The modern multi-grade<br/>oils exhibit the non-Newtonian characteristics which are beneficial for an effective lubrication of the<br/>engines and industrial machinery. In the internal combustion engines, the piston ring assembly is a<br/>crucial component of the power plant. In the four stroke cycle the 1st compression ring is an important<br/>part of the piston ring pack which sustains the main combustion thrust directly. It is vulnerable to all<br/>forms of dynamic loads during the extreme and unusual engine operating conditions. When an engine<br/>starts up, the 1stcompression ring is most vulnerable to wear due to the absence of a fully established<br/>Elastohydrodynamic Lubricating (EHL) film. In this context, the viscoelastic behavior of anon<br/>Newtonian lubricant may contribute towards preventing wear of the interacting surfaces of the top ring<br/>and the cylinder liner. Role of oil behavior to minimize adhesive wear of piston skirt and liner surfaces<br/>during engine start up conditions under ideal conditions have yet to be properly modeled and<br/>thoroughly investigated. This calls for proper investigative research to model rheological behavior of<br/>non-Newtonian engine lubricants with particular focus on initial engine start up conditions.<br/>This research work will numerically model the hydrodynamic and Elastohydrodynamic<br/>Lubrication (EHL) of the 1st compression ring by considering the Newtonian and Non-Newtonian<br/>lubricant characteristics for comparative analysis. The secondary dynamics of the piston will be<br/>incorporated in the models at the different engine startup speeds, lubricant viscosities and radial<br/>clearances for optimum solutions. |
