Abstract: A drive for a vehicle includes an internal combustion engine having a combustion chamber delimited by a cylinder and a piston, a compressed gas storage connectable with the combustion chamber for storing a gas compressed in the combustion chamber, a separate expansion machine for expanding compressed gas from the combustion chamber or from the compressed gas storage by performing mechanical work, and devices for supplying gas from the expansion machine into the combustion chamber or into an intake passage of the internal combustion engine. The drive may, alternatively or in addition, also include devices for heating the compressed gas from the combustion chamber or from the compressed gas storage before the compressed gas enters into the expansion machine.

Abstract: A motor vehicle includes a combustion engine and an intake tract for feeding air to the combustion engine. A compressor is arranged in the intake tract for compressing air, and a turbine is arranged in the intake tract downstream of the compressor and powered by air compressed in the compressor.
