A two-stage free-piston driver

open access: yesShock Waves, 1999
The overall cost of free-piston driven facilities can be substantially reduced if the contraction between the compression and shock tubes is replaced with a constant area section. However, with such an implementation, a new driver concept is required in order to achieve a realistic facility length. This paper describes a new free-piston driver type for

A review of free-piston linear engines

Applied Energy, 2016
Abstract Unlike conventional internal combustion engines, a free-piston linear engine has no a crankshaft, and thus the pistons move freely in the cylinder. This allows a free-piston linear engine to easily adjust the compression ratio and optimize the combustion process.

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.
