The mechanization of a hot air engine cycle consisting of constant temperature compression, heat added from regeneration at constant pressure, energy stored, heat added at constant volume, adiabatic expansion, stored energy used, adiabatic expansion, and heat rejected to regeneration. Constant temperature compression is achieved by using a multi-stage-intercooled compressor. Heat is added at constant pressure by means of an exhaust gas to compressed air heat exchanger. Energy is stored in the compressed air tank. Heat is added at constant volume by means of a two-piston arrangement in the expansion cylinder. Adiabatic expansion takes place. Energy from storage is used. Adiabatic expansion takes place all the way to ambient pressure. The displacement of the resulting engine can be varied while the engine is running. The engine has dynamic braking by means of an alternator charging a battery. The battery power is used to drive a compressor.
