The invention discloses a four-stroke or two-stroke internal combustion engine using liquid carbon dioxide. Three heat cycle devices of the four-stroke or two-stroke internal combustion engine convertpart of heat of waste gas exhausted by the internal combustion engine, cooling waste heat, human body dissipated heat and climate heat into mechanical energy, and heat efficiency of the internal combustion engine is greatly improved. Compared with a water jet type six-stroke internal combustion engine, the problem that a pipeline is blocked by a water-oil combination does not exist; cold energy released by the liquid carbon dioxide is used for refrigeration, air condition compressors of traditional boats and carts are omitted, and the driving power of boats and carts is optimized; there are no fans for cooling, air inlet gratings of vehicles are omitted, vehicle head layout is simplified, and wind resistance and noise are reduced; and due to cooling in cylinder and heat exchange and energy absorption of the carbon dioxide, an internal combustion engine cabin and high-temperature releasing of tail gas are eliminated, and infrared detecting and tracking are easily avoided.

    本发明公开了一种使用液体二氧化碳的四冲程或两冲程内燃机,本发明的三套热循环装置将内燃机排放废气热、冷却废热、人体散热和气候热的一部分转化为机械能,极大地提高了内燃机的热效率。本发明与喷水式六冲程内燃机相比没有水油结合堵塞管道的问题,液体二氧化碳释放的冷能用于制冷,省去了传统车船的空调压缩机,优化了车船的行驶动力,无风扇散热,省去了汽车的进气格栅,减化了车头布局,减少风阻和噪音,二氧化碳缸内冷却和换热吸能,消除了内燃机舱和尾气的高温释放,有利于规避红外侦测和跟踪。
