Internal combustion engine waste heat utilization system

A high-efficiency and energy-saving internal combustion engine waste heat utilization technology, wherein a circulation system is installed on an internal combustion engine;

• the circulation system comprises a cooling medium, a cooling medium storage tank, a cooling medium delivery pipe, a circulation pump, a high-pressure pipeline, energy storage tanks, steam turbines and a radiator, the cooling medium is a substance with a low boiling point under normal pressure;
• the cooling medium storage tank is connected with a circulation pump through the cooling medium delivery pipe;
• the circulation pump is connected to a circulation liquid inlet of the internal combustion engine through a connecting pipe;
• a closed interlayer is arranged on an outer wall of an exhaust pipe of the internal combustion engine;
• a circulation liquid outlet of the internal combustion engine is connected to one end of the interlayer of the exhaust pipe, and the other end of the interlayer of the exhaust pipe is connected with the energy storage tank through the high-pressure pipeline;
• the energy storage tank is connected with the steam turbines;
• output ends of the steam turbines output kinetic energy;
• and a gas-liquid mixture after doing work enters a cooling fin, and is completely liquefied to enter the cooling medium storage tank for a next cycle.
