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.

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.

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. It also directs the spent exhaust gasses out of the torus.
