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

Green Car Congress

The injection of the additional air during transients can overcome the poor driveability usually associated with heavily downsized and supercharged engines, the team notes. In the pneumatic hybridization scheme, each cylinder is connected via a fully variable charge valve to a shared pressure tank. Dönitz et al. Source: ETH Zürich.

UK LowCVP Launches ‘Technology Challenge’ to Accelerate Low Carbon Vehicle Innovation; Libralato Engines First Registrant

Green Car Congress

Induction air enters at the center of the engine and compression/expansion occurs at the periphery producing uniform heat flow characteristics as air circulates around the two sides of the engine. The two rotors are connected together by a connection rod that has a quasi-circular orbit. Overview of the Libralato Engine.

Concept: Garric Rotary Variable Compression Ratio Engine

Green Car Congress

The Garric engine divides the four elements of intake, compression, combustion and exhaust among multiple double-faced pistons moving in a constant direction. The central hub (or power shaft) is connected to a disc with one or more pistons attached. A detailed animation of the cycle is available on the Garric Engine website.
