Journal Article
Zhang, Z., Feng, H., Jia, B., Zuo, Z., Yan, X., Smallbone, A., & Roskilly, A. P. (2022). Identification and analysis on the variation sources of a dual-cylinder free piston engine generator and their influence on system operating characteristics. Energy, 242, Article 123001. https://doi.org/10.1016/j.energy.2021.123001

Stable combustion is a huge challenge for dual-cylinder free-piston engine generator (FPEG). Combustion variations are easy to occur, because the piston movement is only affected by the forces acting on the moving parts, and there is no mechanical st...
