Numerous components from the SLS AMG Coupé Electric Drive ( earlier post ) have been integrated in the design of the “Cigarette AMG Electric Drive Concept” engineeringdesign. The liquid-cooled lithium-ion high-voltage battery features a modular design with a maximum voltage of 400 V.
The companies are developing an improved axial vane type rotary engine known as the RadMax. The RadMax design was mainly developed by Radian Milparts and assigned to REGI US, Inc. The new vane actuator assembly reduces weight and friction, and the vane actuator design does not require any return springs. in December 2005.
The Scuderi Engine is a split-cycle design that divides the four strokes of a conventional combustion cycle over two paired cylinders. Intake air is compressed in the compression cylinder and transferred to the power cylinder for combustion. a more efficient internal combustion engine. Earlier post.).

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. By cogenerating power from gas and steam, vv-tec claims, the Reinhardt Turbine.
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.
The new FOA supports the President’s EV Everywhere Grand Challenge, which seeks to make the United States the first country to produce a wide array of plug-in electric vehicle (PEV) models (including plug-in hybrids and all-electric vehicles) by 2022 that are as affordable and convenient as current gasoline powered vehicles we drive today.
Researchers at ETH Zürich, with partners Robert Bosch GmbH, Wenko Swissauto and the Swiss Federal Office of Energy are developing a downsized and supercharged hybrid pneumatic engine that they say can deliver a fuel consumption reduction of more than 30% compared to a standard engine with the same rated power. Earlier post.).
Regarding HCCI, it has been reported that a high compression ratio realizes more efficient combustion characteristics, and a VCR mechanism that can simultaneously realize improved fuel economy and power performance has been demanded.

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. Piston motion is the final major engine parameter that remains to be digitally controlled by the ECU rather than mechanically governed.
The partnership involves using select conventional vessels from EPS’ existing tanker fleet that use MAN engines to be retrofitted, allowing them to be powered by methanol and ammonia which will be supplied by OCI. Also, EPS will construct newbuild vessels with MAN enginespowered by the same two alternative marine fuels.
