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 a compression ratio of 9.0, Dönitz et al.

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.

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.

Heat hybrid. A cryogenic engine such as the Dearman engine could also be used as a heat hybrid in combination with an internal combustion engine or hydrogen fuel cell to convert waste heat into additional shaft power at high levels of efficiency, reducing both fuel consumption and emissions. The Dearman engine.
