Abstract

The change of the inlet angles in inlet ports to variations of the scavenging process in two-stroke uniflow-scavenged engine is presented in the paper. The values of the scavenging have been obtained by means of the model-tests using liquid instead of exhaust gases and scavenging air. 1 Introduction The scavenging system in two-stroke uniflow-scavenged engines should provide a good exchange of gases and generate a suitable rotary motion of fresh air in the cylinder. It must be ensured that the rotational speed of fresh load in the cylinder provides good mixing of air and injected fuel, which conditions a proper combustion. The resistance of flow through scavenging system should be as small as possible, so that the load exchange is performed
