Development of a Single-Cylinder Four-Stroke Free-Piston Generator

Abstract:

Free-piston engines are under investigation worldwide recently for their potential advantages in terms of efficiency and emissions. This paper focuses on the development and performance of a novel four-stroke free-piston generator (FSFPG), which is designed from a four-stroke free-piston engine equipped with a linear electric generator. Working principle and operating characteristics of the FSFPG are discussed, along with potential advantages and disadvantages compared to conventional engines. The design process and geometric parameters of a single cylinder, gasoline and spark ignition FSFPG prototype is presented. The control strategy of the novel power generating system is discussed. The already obtained testing results and performance of the FSFPG prototype are presented and analyzed in this paper in detail.
