1. An over expanded, limited temperature cycle for operating an engine comprising:

  • a compression process 1-2-3, said compression process 1-2-3 further comprising;

    a first compression process 1-2 carried out via an external compressor; and

    a second compression process 2-3 carried out by changing the volume of a cylinder of said engine;

    a heat addition process 3-4-5, said heat addition process 3-4-5 further comprising;

    a first heat addition process 3-4 carried out via injection and combustion of fuel in said cylinder of said engine while maintaining a constant pressure; and

    a second heat addition process 4-5 carried out via injection and combustion of fuel in said cylinder while maintaining a constant, limiting temperature;

    an adiabatic expansion process 5-6;

    a heat removal process 6-7-1, said heat removal process 6-7-1 further comprising;

    a first heat removal process 6-7 under a constant volume; and

    a second heat removal process 7-1 under constant pressure;

    wherein said compression process, said heat addition process, said adiabatic expansion process, and said heat removal process combine to form an over expanded, limited-temperature cycle 1-2-3-4-5-6-7-1.
