Abstract
Compared with experimental and theoretical approaches modeling of the scavenging process in a two-stroke engine offers great advantages on account of its simplicity and economy. The clear definition of influencing factors and a better physical interpretation of the model laws governing the flow process help to design the model and to determine the test conditions; the model laws also allow the obtained test results to be transferred to the prototype.
A relatively simple and inexpensive liquid model presented enables qualitative observations and quantitative evaluations of different port configurations to be made. For the design of port configurations some recommendations are presented.
The short circuiting and instabilities in scavenging test results are also mentioned.
