Abstract
The invention relates to a free-piston engine that is connected to a pre-compressor (14) and a turbine (16) by pressurized gas. The free-piston engine (18) according to the invention has at least one piston (20) that can be reciprocated in a cylinder compartment and divides the same up into two combustion chambers (36, 38), the pre-compressor being operable electrically and/or assisted by exhaust gas.
