Summary:

2-D LDV measurements were performed in the cylinder of a two-stroke engine. The transfer channels of the cylinders were of two different designs: Open transfer channels and "cup handle" transfer channels. The engine was run at its rated speed, 9000 rpm.Optical access to the cylinder was achieved by replacing the standard cylinder head with a quartz window. No addition of seeding was made, since the fuel droplets were not entirely vaporized as they entered the cylinder and thus served as seeding.Results show that the flow out from the cup handle transfer channels is more directed away from the exhaust port, which promotes loop scavenging.The RMS-value, "turbulence", was low close to the transfer ports in both cylinders, but increased rapidly towards the middle of the cylinder
