Computational flow analysis in combustion chamber of CI-Engines

Author(s): M Raman ME
Abstract: Recent years have witnessed rapid developments in the fields of IC engines. Today both the manufacturers and the customers are looking for low polluting and better efficient engines. Basically, the in-cylinder gas motion affects the performance of the engine. So, it is necessary to have a better control over in-cylinder gas motion. With the experimental techniques that are available today, it is possible to make reasonably accurate measurements to study the in-cylinder flow characteristics. But they are costly and time consuming. Over the past one and half decades, fluid dynamic based multi-dimensional models for studying fluid dynamics in-cylinder gas motion are being tried in IC engine field. The main objective of the project is the flow calculation of the compression and expansion stroke of a four-valve direct-injection. Direct engine have been carried out with different combustion chambers. In the main study, the flow characteristics inside the engine cylinder equipped with different piston configuration were compared, for this, complete calculations of the compression and expansion strokes were performed under realistic operating conditions and the ensemble-averaged velocity and turbulence flow field obtained in each combustion chamber analyzed in detail.
