liter X4V2 prototype was originally designed for an aviation application. Revetec has prototyped 6 different versions of Revetec engine designs over the last 10 years. The latest version, the X4V2, was designed as a development engine for the aviation industry, and in early 2008 it was independently tested by Orbital Australia.

Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change.

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 cryogenic engine such as the Dearman piston engine produces zero emissions at the point of use; has low greenhouse gas emissions provided the liquid air or nitrogen is produced from low carbon electricity; has energy and power density on a level with battery electric technology; and has the potential for rapid refueling.

Shifting the operating point of the engine is also possible, using at least one cylinder in a conventional combustion manner at high load, and using at least one cylinder to pump air into the pressure tank. In large naturally-aspirated SI engine, high-friction, pumping losses and part-load operation all contribute to poor fuel efficiency.

It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve. Considering the thermal efficiency and combustion efficiency, the air jet pressure should be designed as low as possible in the circumstance that the autoignition can occur.

This technology will allow researchers to develop future combustion engines free from the piston motion constraints dictated by the crankshaft. Already validated at proof-of-concept level, Libertine’s new hardware uses production-feasible component designs suitable for automotive hybrid powertrain modules, such as range extenders.
