A reciprocating engine without a crank-slider mechanism is called a free-piston engine. If the
piston is directly connected to a linear alternator, it is called a free-piston linear alternator …

Free-piston engine generators (FPEGs) have huge potential to be the principal energy
conversion device for generating electricity from fuel as part of a hybrid-electric vehicle (EV) …

The free-piston engine linear generator (FPELG) is being investigated by many researchers
because of its high thermal efficiency and its variable compression ratio. However, all …

Free-piston engine generator is a novel electrical power generating system developed for
electric vehicles, and it is labeled as a more efficient power system than conventional …

Free-piston engine generator is a novel energy conversion system, which is known to have
advantages of variable compression ratio and variable fuel. The free-piston must be …

A free-piston engine (FPE) is a linearly-reciprocating internal combustion engine (ICE)
which offers many advantages over the conventional crank-slider ICE. Benefits include …

This article describes a novel approach to the design of linear machines that are not run at a
steady-state operating point. The focus lies on minimizing the power loss to achieve highest …

(FPLG) attracts more research on its stable operation and power performance, while less on
its combustion and emission performance. So, in this paper, the emission characteristics of …

Abstract Free Piston Engine Generators (FPEG) directly convert the reciprocating piston
motion into electricity by using a linear alternator. Unlike conventional engines with piston …

In power/energy systems, free-piston linear machines are referred to as a mechanism where
the constrained crank motion is eliminated and replaced with free reciprocating piston …
