Abstract

In this paper the numerical model that calculates the fluid dynamics in an engine cylinder which is represented in the first part of this paper (1) is used to simulate the compression stroke. The calculated results are presented For a cupped piston geometry under operating conditions typically of those contemplated for direct injection diesel engine Particular emphasis is placed on the spatial and temporal distribution of the Flow, velocity vectors and contour lines, Swirl intensity and swirl centers. Although many of the detailed features of the turbulent flow are still unresolved, some progress of the understanding of the in-cylinder flow specially near the top of the dead center (TDC) is gained.
