Abstract

A three-dimensional flow in the intake process of a reciprocal engine is calculated numerically under such complicated boundary conditions as moving valves and arbitrary intake-port and combustion chamber configurations. A finite difference method using a third-order upwind scheme for convective terms is applied to solve incompressible Navier-Stokes equations. This model enables us to simulate the occurence of small vortices near the valve and valve seat or caused by curvature of the intake port, as well as the influence on flow in a cylinder of the vortices. The difference in flow pattern between single and double intake valves is compared as an application of this model.
