Examination of a Free-piston Engine Linear Generator System with Opposite-side Combustion

2019 12th International Symposium on Linear Drives for Industry Applications (LDIA), 2019
A Free-Piston Engine Linear Generator System is expected to be applied to a hybrid car. Previous studies have presented a one-sided FPEG that uses a combustion chamber and an air spring chamber. However, loss of the air spring chamber has been observed.

Quad-cylinder Structure for Electrical Loss-reduction in Free-piston Engine Linear Generator with Four-stroke Engine

2022 IEEE 7th Southern Power Electronics Conference (SPEC), 2022
A new energy conversion device is the free-piston engine linear generator (FPEG) without a crank mechanism. Among these, the four-stroke FPEG engine is regarded as a highly efficient engine generator that complies with emission laws. However, because the

An Investigation on Power Generation Characteristics of Linear Generator Driven by a Free-piston Engine

2021 International Conference on System Science and Engineering (ICSSE), 2021
There are many energy sources converted from PMLG (Permanent Magnet Linear Generator- PMLG) linear generator such as wave energy, free-piston engine. This paper proposes the design and study of a single-phase PMLG with a simple structure. Using motion simulators, the objective is to investigate the PMLG's operation at low moving speeds from 0.25 m/s to

Examination of a free-piston engine linear generator system with generation control for high efficiency

2017 11th International Symposium on Linear Drives for Industry Applications (LDIA), 2017
A free-piston engine linear generator system is investigated for use as a high-efficiency generator engine. The system's efficiency depends on its generation and thermal efficiency, and the generation efficiency is degraded at the edge of the expansion stroke when the piston speed is low and the thrust is high.

Modeling and Design of a Tubular Linear Generator for Direct-Drive Free-Piston Engine

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
This paper focuses on the sizing approximation and parameter estimation of a Linear Generator (LG) to be driven by a direct drive free-piston engine. The modeled and designed LG is of tubular topology comprising of an outer stator with a 3-phase winding configuration and inner slider having layers of axially magnetized PMs and spacers.

Examination of Miniaturization Using a Double Stator for a Free-Piston Engine Linear Generator System

2018 21st International Conference on Electrical Machines and Systems (ICEMS), 2018
A free-piston engine linear generator (FPEG) system is a linear generator, which generates electricity when a free piston reciprocates the combustion thrust produced by internal combustion. It is expected that this system can be applied to hybrid vehicles. In this paper, we propose a cylindrical double stator linear synchronous generator to exclude the

State Estimation Algorithm Based on a Disturbance Observer for a Free-Piston Engine Linear Generator

Journal of Dynamic Systems, Measurement, and Control, 2016
In order to realize a thin, compact, efficient, and fuel-flexible power-generation system, we have been developing and investigating a free-piston engine linear generator (FPEG), which consists of a two-stroke combustion chamber and an adjustable gas spring chamber. This paper proposes a novel observer algorithm that has two advantages.
