Experts view on future transportation fuels

Green Car Congress

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.

Australian Cam-Drive Gasoline Engine Reaches 39.5% Efficiency in Independent Testing; Potential for Production Engine in China

Green Car Congress

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.

Concept: Compact Two-Cycle, Co-generating Piston-Driven Turbine to Deliver 60+% Efficiency

Green Car Congress

Gert Reinhardt was trained as a Mathematician at Dortmund University. Gert also designed a storage jukebox that was used by many of the largest companies in Europe. The engine is classified as a turbine, says Jim Andrews, vv-tec’s President, because the use of the sinus discs make the engine into an impulse turbine.

Dalian team proposes jet controlled compression ignition to control PCCI phasing in a hybrid pneumatic engine

Green Car Congress

Researchers at the Dalian University of Technology have proposed a novel method to control premixed charge compression ignition (PCCI) phasing in internal combustion engines in all load operations. Higher air jet temperature can obtain a higher and advanced peak pressure.
