CFD In-Cylinder Flow Simulation of an Engine and Flow Visualization 950288

Multi-dimensional transient scavenging flow simulation of a schnule scavenged two-stroke cycle engine has been carried out under motoring conditions. This paper presents the differences of the flow characteristics between crankcase compression and roots blower scavenging, obtained by different initial and boundary conditions of scavenging pressure. Furthermore, the influence of scavenging port's slant angle are shown by using the CFD visualization technique.
