The free piston engine linear generator (FPELG) is a simple structure engine with only two
main parts, ie, the linear generator and a free piston engine, which has less friction, low …

Linear engines, or widely called free piston engines, have their advantages compared to
conventional engines with crankshafts, for example, lower friction loss, compact structure …

This paper proposes a novel sensing system for the non-intrusive real-time measurement of
piston position inside a cylinder. The proposed sensor exploits the principle that any …

Free-piston linear generators (FPLGs) have attractive application prospects for hybrid
electric vehicles (HEVs) owing to their high-efficiency, low-emissions and multi-fuel …

The proposed paper deals with the development process and initial measurement results of
an opposed-piston combustion engine for application in a Free-Piston Linear Generator …

The hydraulic free-piston engine (HFPE) is a kind of hybrid-powered machine which
combines the reciprocating piston-type internal combustion engine and the plunger pump as …

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 …

The hydraulic load-sensing system is a more efficient system solution than constant
pressure system in mobile machine. However, the overall system efficiency for multiple …

The free-piston engine has a unique internal-combustion engine architecture which features
unconstrained piston movement because the crankshaft has been removed. The engine …

This paper presents a stable control method for free-piston linear generator (FPLG) based
on online trajectory planning. The single cycle movement of the piston is divided into two …
