Micro Abstract:
The fuel efficiency of an internal combustion engine is directly related to the performance of the piston ring pack. We present our numerical study of compressible gas flow in the ring pack. Namely, a two-dimensional transient full engine working cycle simulation considering the fluid-rigid-body interaction between piston ring and surrounding fluid, and a three-dimensional simulation of the flow through the ring gap investigating the gap's suction effect.
