Constraint enforcement of piston motion in a free-piston engine

2014 American Control Conference, 2014
Precise control of piston turnaround location is essential for reliable free-piston engine (FPE) operation. In this paper we derive a discrete-time, control-oriented, implicit model that describes FPE clearance height behavior by applying an energy balance to the Otto cycle.

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.

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.

Precise piston trajectory control for a free piston engine

Control Engineering Practice, 2015
Abstract A free piston engine removes the mechanical constraint on the piston motion by eliminating the crankshaft. The extra degree of freedom offers many advantages for reducing fuel consumption and emissions. Nevertheless, stability and robustness of the engine operation has been affected in the meantime.

Motion control of a hydraulic free-piston engine

2012 American Control Conference (ACC), 2012
Free-piston engine (FPE), as an alternative of the conventional internal combustion engine, has a high potential in terms of energy saving given its wide range of potential applications and high efficiency. One of the technical barriers that prevents the wide spread of this technology is the lack of precise piston motion control.
