Parametric Simulations on Leakage and Performance of a Miniature Free-Piston Generator (MFPG)
The miniaturization of electrical equipment and popularization of portable devices is an appealing motivation for the development of small-scale heat engines. However, the in-cylinder charge leaks severely as the engine dimension shrinks. The free-piston

A review of free piston engine control literature—Taxonomy and techniques
The free piston engine linear generator (FPELG) is a simple structure engine with only two main parts, i.e., the linear generator and a free piston engine, which has less friction, low emission, high thermal efficiency, and multi-fuel engine.
