The in-cylinder flow of a reciprocating piston engine is simulated numerically for the intake and compression stroke. A block structured moving grid system is applied to resolve the piston and valve movements. The grid is refined and coarsened during the opening and closing of the valve and the piston up- and downward motion. In addition to the conservation equations for mass, momentum and energy, a conservation equation for the cell volume is solved numerically. No turbulence model is applied, because large eddy simulations of a turbulent channel and plane jet flow show that the influence of subgrid scale models is small for second order schemes. Results are presented for one and four valve engines also in comparison with experimental data.
