HEAT ENGINES AND ASSOCIATED METHODS OF PRODUCING MECHANICAL ENERGY AND THEIR APPLICATION TO VEHICLES

摘要

A closed cycle gas turbine system (40) comprising system comprising a compressor (52) for producing compressed gas, a gas turbine (42) for receivi ng the compressed gas, a heat storage means (44) having a first heat transfer means and adapted to receive the compressed gas from the compressor (52) and transmit the compressed gas to the gas turbine (42) and a second heat transf er means (46) for receiving exhaust gas from the gas turbine (42) and transmitting it to the compressor (52) and wherein the second heat transfer means (46) is adapted to transfer at least some heat from the exhaust gas prior to it being transferred to the compressor (52).
