Oil Loss Mechanisms Due to in-Cylinder Components (2000)

 

 

Oil loss in internal combustion engines has been a concern for a long time. With the advances in manufacturing technologies and an improved understanding of engine tribology the oil loss in automotive applications has been continuously reduced. Increased awareness regarding environmental pollution and tightened regulations necessitates the study of oil loss to emissions. Oil transport inside the cylinder is also intimately linked to piston and ring performance, friction loss and blowby. Therefore, an understanding of oil loss and the relevant oil transport characteristics is imperative for improved component and engine design. Due to the complex nature of oil transport mechanisms and a lack of experimental investigation of underlying individual physical phenomena, modeling efforts have so far been limited compared to other in-cylinder issues such as ring and piston dynamics and blowby. This paper summarizes the known and conceptualized oil loss mechanisms believed to contribute to engine oil loss through in-cylinder components. [via]
