Two-Stroke Thermodynamic Cycle Optimization of a Single-Cylinder Free-Piston Engine Generator [PDF]
Advances in Materials Science and Engineering, 2019 A free-piston engine generator (FPEG) is a new type of energy converter, which eliminates the crankshaft and connecting rod mechanism. In order to achieve efficient energy conversion, the two-stroke thermodynamic performance optimization of a single-cylinder free-piston engine generator is investigated in this paper.
