loop scavenging

A method of scavenging used on two-stroke motorcycle engines. The entering gas streams travel across the piston, up the far side of the barrel and curl over and down to complete the scavenging process; loop scavenging is sometimes used to refer specifically to a special variant of this type of scavenging: Schnürle scavenging
