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 receiving 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 transfer 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 ).
