TL;DR: In this article, a linear alternator is mounted in the center section of a double-ended cylinder, serving to both generate useful electrical power and to control the compression ratio by varying the rate of electrical generation.
Abstract: Sandia National Laboratories has been investigating a new, integrated approach to generating electricity with ultra low emissions and very high efficiency for low power (30 kW) applications such as hybrid vehicles and portable generators. Our approach utilizes a free piston in a double-ended cylinder. Combustion occurs alternately at each cylinder end, with intake/exhaust processes accomplished through a two stroke cycle. A linear alternator is mounted in the center section of the cylinder, serving to both generate useful electrical power and to control the compression ratio by varying the rate of electrical generation. Thus, a mechanically simple geometry results in an electronically controlled variable compression ratio configuration.
TL;DR: In this paper, a review of different designs and operating characteristics of free-piston linear engines is presented, as well as varied experimental systems and applications of FPL engines and their applications.
