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

Green Car Congress

The wave disc engine, a new implementation of wave rotor technology, was earlier developed by the Michigan State group in collaboration with researchers from the Warsaw Institute of Technology. The WDG also can reduce carbon dioxide emissions by as much as 95 percent in comparison to modern internal combustion vehicle engines.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The injection of the additional air during transients can overcome the poor driveability usually associated with heavily downsized and supercharged engines, the team notes. The engine has two intake and two exhaust valves per cylinder.

Bladon Jets, SR Drives and Jaguar Land Rover Win Funding for Gas Turbine Electric Vehicle Project

Green Car Congress

Bladon suggests that in an hybrid vehicle application, with no water-cooling system, oil or catalytic converter, the Micro-Jet engine can provide vehicle weight savings of up to 15%—with a consequent reduction in fuel consumption and carbon emissions—compared to a piston engine. Clean burn annular combustion chamber.
