Abstract
As the automotive tail pipe emission norms are becoming stringent day by day, the engine manufacturers are concentrating more on reducing the engine emissions like CO, HC, NOx and particulate matter. The reduction of oil consumption & blow-by plays an important role in achieving this objective. For this reason the OEM's strongly demand pistons and piston ring pack, which can offer low oil consumption and blow-by. Therefore it becomes necessary to study the axial and radial motions of the rings and inter ring gas pressures, as they are considered to be important factors affecting the control of oil consumption and blow-by. The development of ring pack for low oil consumption needs a lot of theoretical iterations and experimental verification which are very costly and time consuming, as the process involves a number of prototypes and dynamometer tests. In order to minimize multiple design iterations and testing, organizations tend to use engine performance simulation tools. In this paper, the approach towards re-optimizing oil consumption in a four stroke DI diesel engine has been presented. Ricardo RINGPAK software has been used for the simulation. Thermal analysis has been carried out using ANSYS software for predicting the temperature distribution of piston and liner required as input for the RINGPAK analysis.
