Free-piston engines have been under extensive investigation in recent years, however have
not yet seen commercial success in modern applications. This paper reviews some of the …

This paper focuses on the numerical modelling of a spark ignited free-piston engine
generator and the model validation with test results. Detailed sub-models for both starting …

This paper presents an experimental investigation of the starting process of a prototype free
piston engine generator (FPEG). Experimental test results show that during the motoring …

A dual-piston type two-stroke spark-ignition free-piston engine generator prototype has been
developed. A comprehensive review on recent published researches and patent documents …

We present a novel design of a single-cylinder free piston engine linear generator (FPELG)
incorporating a linear motor as a rebound device. A systematic simulation model of this …

In this paper, we present our experiment and simulation study of a free piston linear engine
based on operating conditions and structure of the linear engine for generating electric …

It is important to identify the relationship between the starting requirements and the structure
parameters of the diesel free piston linear alternator on the structural design stage. In this …

The free piston linear engine (FPLE) generator has the potential to displace existing
crankshaft driven engine technology because of its relative simplicity, higher efficiency, and …

Compared with the conventional engine, the special characteristic of hydraulic free piston
diesel engine decides its differences in the aspects of piston displacement, velocity …

This paper presents an approach to controlling the extreme positions of a piston in a free
piston generator using linear electrical machine. The machine is used to provide the proper …
