Abstract
An improved mathematical model is presented here to simulate the gas exchange of a two-stroke, cross or loop-scavenged engine. In this model, the geometry of the cylinder and port assemblies, as well as the physical conditions of operation are fully represented. The basic model which was described by the present author in a former work, has been modified here to include the Woolley-Hatton model for turbulent flow. By comparing predictions from both models with experimental measurements, it seems that a significant improvement was achieved here in predicting the instantaneous interface profile between the incoming charge and the burnt gas.
