  "textContent": "A device for recovering waste heat from internal combustion engines, which is constructed as follows. Operation of an internal combustion engine (1) produces first and second temperature-rise sections (202, 204). The degree of temperature rise is greater in the first temperature-rise section (202) than in the second temperature-rise section (204). The first evaporator (205) of an evaporation means (3) produces first vapor having its temperature elevated by utilization of the first temperature-rise section (202). The second evaporator (206) thereof produces second vapor having its temperature elevated by utilization of the second temperature-rise section (204) and having a pressure lower than that of the first vapor. The first energy converter (207) of a positive-displacement expander (4) converts the expansion energy of the first vapor into mechanical energy. The second energy converter (208) thereof converts the expansion energy of the second vapor into mechanical energy. Both mechanical energies are integrally outputted. A condenser (5) liquefies the first and second pressure-dropped vapors. A feed pump (6) pressurizes and feeds the liquid from the condenser (5) into the first and second evaporators (205, 206).",
