Abstract
Compressible flows in a model engine with a square piston were analyzed during continuous engine cycles by using an accurate numerical simulation method and an orthogonal homogeneous grid without grid motions. The cycle-by-cycle differences, i.e., cyclic variations, in flow fields are examined in order to find more effective ways of stabihzing combustion. It is stressed that there are "stable domains", where the cyclic variations are relatively weak near the end of compression.
