Abstract

The importance of flow patterns in internal combustion engine is to intensify the performance of the engine in presence of swirl and tumble. Therefore, it is crucial to investigate the flow behavior at the intake valve. In this research, the effects of valve lift to the flow pattern inside the engine are to be investigated. Computational Fluid Dynamic is used to predict the flow behavior in the single cylinder engine. The higher velocity during intake stroke is believed to increased swirl and tumble throughout compression stroke. Besides analyzing the flow behavior, the findings of this project will helps in increasing the performance of engine. Results of the simulation are presented in graphical data in terms of swirl pattern and tumble pattern. Besides, the graph of the Turbulence Kinetic Energy is presented to support the results. A maximum value is compared for all four parameters. The parameters are taken from different valve lift from the lowest to the highest valve lift. From the result, it is found that the lower valve lift results in better swirl, tumble and turbulence kinetic energy value. This gives off better performance to the engine.
