Dynamic Stability of Free Piston Stirling Engines

14th Biennial Conference on Mechanical Vibration and Noise: Nonlinear Vibrations, 1993
Abstract A Stirling engine develops work output from a thermal input. It is a quiet pollution free engine, which can use any heat source, including solar power. The piston-displacer mechanism is essentially a vibrating spring mass system and can be dynamically modelled, leading to a set of coupled nonlinear ordinary differential ...

Friction characteristics of piston rings in a free-piston engine generator

International Journal of Engine Research, 2016
Free-piston engine generator is a new alternative to traditional reciprocating engine, which moves without mechanical restriction of crankshaft system. This article investigated numerically the friction characteristics of piston rings in a free-piston diesel engine generator by adopting coupled models of dynamic and friction.

A Review of Free Piston Engine Concepts

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">In free piston engines, the stroke of the piston is used directly to produce hydraulic, pneumatic or electric energy. This can be done with a single piston in one combustion chamber, or with more pistons in one or more combustion chambers.

Hybrid simulation of a free piston engine

Proceedings of the April 26-28, 1966, Spring joint computer conference on XX - AFIPS '66 (Spring), 1966
The free piston engine principle is one which has intrigued mechanical engineers for decades. Indeed, the original gas engine of Otto and Langden employed a piston assembly which did not contain the now conventional connecting rod and camshaft arrangement and hence may be considered as an early implementation of the free piston principle.
