million contract modification to apply the technology in its thermoelectric generator (TEG) for passenger cars to a similar program for heavy vehicles. The TEG technology, which converts waste heat from gas exhaust into electric energy and has the potential to improve passenger car fuel efficiency by as much as 5%. Click to enlarge.

About the size of a large cooking pot, the novel, hyper-efficient engine could replace current engine/generator technologies for plug-in hybrid electric vehicles. The WDG also can reduce carbon dioxide emissions by as much as 95 percent in comparison to modern internal combustion vehicle engines. Norbert Müller. The Wave Disc Engine.

The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. This method of maintaining temperatures is equally suited for all kinds of vehicles and in all climate zones, although it is somewhat more effective at low temperatures.

In addition to the TARDEC work, Achates has two other programs in play, Johnson said, one for commercial vehicles, and another for non-wheeled vehicles. Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Cutaway of power module concept, showing internal gear train.
