Each cylinder fires twice per revolution and two cylinders fire simultaneously, resulting in four times the output per revolution of a conventional four-stroke engine at the same displacement. The engine can be adapted to run any combustible gas or liquid as fuel. Tags: Concept Engines. OX2 in a test rig.

UK-based Libertine FPE has built a demonstration prototype of its linear electrical machine for what it is calling “Digital Piston Motion Control” in free piston engine applications. This technology will allow researchers to develop future combustion engines free from the piston motion constraints dictated by the crankshaft.

A German company, vv-tec GmbH , is developing a compact piston-driven turbine—the Reinhardt Turbine, named after its inventor—that it says is a two-cycle (gas and steam) thermodynamic process machine that can be built with conventional components and can achieve efficiency of at least 60%. The engine components are contained within a sphere.

A researcher at the Nanjing University of Science & Technology is proposing a novel opposed-piston free-piston linear generator for use in series hybrid electric vehicles. The effects of [HCCI] operation will be investigated by future accurate combustion model. Furthermore, natural gas will be investigated as the fuel of the system.
