Free piston internal combustion engine linear generator (FPELG) is a novel energy
conversion device. Compared with traditional rotary internal combustion engines, FPELG …

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 …

This paper focuses on the numerical modelling of a spark ignited free-piston engine
generator and the model validation with test results. Detailed sub-models for both starting …

Free-piston engines have been under extensive investigation in recent years, however have
not yet seen commercial success in modern applications. This paper reviews some of the …

This paper presents an experimental investigation of the starting process of a prototype free
piston engine generator (FPEG). Experimental test results show that during the motoring …

Free-piston engines are under investigation by a number of research groups due to potential
fuel efficiency and exhaust emissions advantages over conventional technology. The main …

Free-piston engines (FPEs) are known to have a greater thermal efficiency (40–50%) than
an equivalent and more conventional four-stroke reciprocating engines (30–40%). Modern …

A piston motion controller for a free-piston internal combustion engine is presented. To
improve dynamic performance in the control of the piston motion and engine compression …

This paper proposes a tubular permanent magnet linear generator (TPMLG) applied to the
free-piston engine generator and establishes a test rig of the TPMLG. A large amount of …

The free-piston engine generator (FPEG) is a linear energy conversion system, which is
known to have greater thermal efficiency than an equivalent and more conventional …
