Abstract
The in-cylinder gas exchange process is crucial to the power performance of two-stroke aircraft piston engines, which is easily influenced by complex factors such as high-altitude performance variation and in-cylinder flow characteristics. This paper reviews the development history and characteristics of gas exchange types, as well as the current state of theory and the validation methods of gas exchange technology, while also discusses the trends of cutting-edge technologies in the field. This paper provides a theoretical foundation for the optimization and engineering design of gas exchange systems and, more importantly, points out that the innovation of gas exchange types, the modification of theoretical models, and the technology of variable airflow organization are the key future research directions in this field.
