In this paper, a novel concept of a finned piston system is presented and analyzed in which the compression heat is continuously extracted from the compression chamber. The resulting compression characteristic moves in the direction of an isothermal

Hydrogen powered vehicles use high-pressure reservoirs from which the gas is transferred to the low-pressure fuel-cell via a classical pressure reduction valve. In these systems no expansion work is recovered and the question is addressed of the pote

A new pneumatic cylinder assembly is proposed as an alternative to classical cylinders which are well known for their poor energetic efficiency. The new system comprises an added expansion volume which permits to recover the energy content of a fille
