There are some photographs of two dimensional flow of loop (M. A. N.) or cross scavenging in the papers by O. Lutz, R. Wille and K. Zinner. In these papers, however, as none of efficiencies about scavenging were made clear, the quantitative relation between scavenging flow and its characteristic is unknown. Under the scheme of investigation of this relation, the experimental results of cross scavenging had been already reported*. The fourth report is the paper about loop (M. A. N.) scavenging. Owing to these experimental results, it became obvious that loop-shaped scavenging flow, which spread fully in the cylinder, as shown in photographs or diagrams by O. Lutz and K. Zinner, had not been formed in the region of the practical delivery ratio. And scavenging efficiency with the practical delivery ratio was higher than that of cross scavenging in the previous paper*.
