Michigan State University Receives $2.5M ARPA-E Award to Build Wave Disc Engine/Generator for Series Hybrid Applications

Green Car Congress

Schematic model of a wave disk engine, showing combustion and shockwaves within the channels. Researchers from Michigan State University have been awarded $2.5 In 1986, Mazda introduced the Mazda 626 Cappela model, which had a 2-liter diesel engine equipped with a Comprex wave rotor (from BBC) used as a supercharger.

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

Green Car Congress

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.
