The H-shaped engine comprises parallel left-side and right-side vertical inline piston banks, each having a crankshaft and pistons, a cylinder head, and individual fuel feeds, but sharing a common power transmission system. The selector control actuates a transfer system that prevents simultaneous operation of both engines.

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.

By over-expanding into adjacent de-activated cylinders, ECONAMIQ creates an additional power stroke within the existing engine architecture, with a significant thermal efficiency increase and cost savings as a result. Using the virtual simulation environment GT-Power, this cycle is applied to a 4-cylinder SI engine.

DOE also announced up to $35 million to advance fuel cell and hydrogen technologies, including enabling the early adoption of fuel cell applications, such as light duty fuel cell electric vehicles. The DOE anticipates making awards that range from $350,000 to $4,500,000, with a 24- to 48-month project duration. Specific Power.

The engine can be adapted to run any combustible gas or liquid as fuel. Advanced Engine Technologies was incorporated in 1996 to commercialize the OX2, with automotive racing pioneer Carroll Shelby on its Board of Directors and involved in the engine development.

Example power cycle of the cryogenic (e.g., liquid air) Dearman piston engine. Source: Dearman Engine Company. The expansion of the liquid air when heat is reintroduced can be used to drive a piston engine or turbine to do useful work. Sources of low-grade waste heat include power stations to factories to vehicle engines.
