ETH Zürich Developing Pneumatic Hybrid Engine; Approaches Hybrid-Electric Performance at Lower Cost

Green Car Congress

Researchers at ETH Zürich are developing a pneumatic hybrid engine—an internal combustion engine connected to a compressed air tank instead of a battery system. The compressed air supply also allows extreme downsizing. Downsizing the engine in this instance halves the number of cylinders from four to two. Rüegg / ETH Zurich.
