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.

Ford Unveils Ford Fiesta for North America at Los Angeles Auto Show; 1.6L I4 with Ti-VCT Delivers Estimated 40 mpg Highway

Green Car Congress

Fiesta features Twin Independent Variable Camshaft Timing (Ti-VCT) ( earlier post ) which allows the engine to be downsized for fuel economy while continuously optimizing camshaft phasing for throttle response, performance and flexibility. The lack of pumps and hoses reduces complexity, saves weight and contributes to fuel efficiency.
