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 hardware concept.

Scuderi Releases Video Footage of Running Split-Cycle 1L Prototype

Green Car Congress

The two-minute video, the first to show the naturally-aspirated one-liter gasoline prototype engine in operation, provides a view of the engine as it undergoes testing, proving the concept of Firing After Top Dead Center. A split-cycle engine is essentially an air compressor on one side with a combustion chamber on the other.

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.

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. It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve.
