In this study, the KIVA-3V CFD code was used to investigate the effect of ports and port angles on the scavenging behaviour of a loop-scavenged free piston engine. A dynamic SIMULINK model that takes into account all forces acting on the piston was used in order to obtain the piston motion. Detailed chemistry combustion simulations using a 3-D sector mesh have been performed for combustion validation purposes. It is shown that low emissions of soot and NOx combined with a decent combustion efficiency are attainable. The scavenging process for different port layouts and port timings has been investigated using the same CFD code, indicating reasonable scavenging characteristics, but these can be further improved.
