A new generation of two-stroke engines has been begun in these days. Environmental requirements are more severe and are pushing for clean engine. The new generation of two-stroke engines represents an interesting answer to the environmental demand for the future. An example of that is a two-stroke diesel engine for automobiles with poppet valves developed by Toyota. In order to ultimately optimize scavenging process using RSSV system for an automotive two-stroke engine, the scavenging flow characteristics is investigated by flow visualization technique under steady condition as a first-stage study. The dye is introduced into the cylinder to observe the path line of the scavenging flow with different RSSV geometries. As working fluid, water is used instead of air to effectively visualize the flow pattern with applying Reynolds analogy.<br/>
