概要

There are several problems regarding of the relation between maximum pressure variation in each cylinder and exhaust and scavenging process in the two-cycle marine diesel engine. In this type of diesel engine, it is not easy to test by the fired engine in practice. Therefore, it can not help to depend on a model test, or a simple test.<BR>In this paper it takes up basical problems associated with the scavenging, and which was discussed how to experiment by using a model. One cycle dynamic model which can be done one cycle scavenging process was made. By this model an experimental study regarding the scavenging carried out. It was found that dynamic effects, that is, the effect of revolution of a model in scavenging efficiency appear slightly, and the density difference of scavenging gas regarding to exhaust gas is affected considerably in the efficiency.
