A Study on the Scavenging Air Flow through the Scavenging Ports

To examine the characters of the scavenging air flow through the scavenging ports in two-stroke engines, the inlet flow pattern through the model ports has been observed by a high speed motion camera, using a single cycle test apparatus. In general, the scavenging air flow is not coincident with the designed direction of the scavenging port at comparatively slight opening, and the efflux direction…
