1. In a power generating system comprising a primary power source and a secondary power source, the primary power source comprising an internal combustion engine, exhaust means for discharging hot combustion products from the internal combustion engine, and closed coolant means confining heat removing fluid in the internal combustion engine;

  • the secondary power source comprising a Rankine cycle power system adapted for utilization of reject heat from the primary source;

    the Rankine cycle power system comprising;

    a. a high pressure vapor generator for vaporizing a working fluid at high pressure;

    b. first means for directing the hot combustion products from the exhaust means into heat exchange relationship with working fluid in the high pressure vapor generator;

    c. a low pressure vapor generator for vaporizing a working fluid at low pressure;

    d. second means for directing the fluid from the coolant means into heat exchange relationship with working fluid in the low pressure vapor generator;

    e. a single expander means for receiving vaporized working fluid from both the high and low pressure vapor generators and adapted to permit both working fluid vapor from the high pressure vapor generator and working fluid vapor from the low pressure vapor generator to expand and perform work simultaneously; and

    f. a condenser for liquifying vaporized working fluid from the high pressure vapor generator and the low pressure vapor generator.
