The invention relates to the field of energy recovery, in particular to an internal combustion engine waste heat recovery system and a transportation tool, a generator containing a [bmim] [PF6] solution containing CO2 is arranged outside a tail gas emission pipeline in a sleeving mode, the solution is heated through tail gas, and high-temperature and high-pressure CO2 steam is generated in a critical zone; steam is cooled by the first heat exchanger and then enters a gas-liquid separator through an expansion valve, separated gas-phase CO2 is directly discharged into the first heat exchanger, liquid-phase CO2 flows into a condenser for condensation through a four-way valve, condensed CO2 flows into an evaporator for evaporation and refrigeration through a first throttling valve, and a CO2 working medium flowing out flows into the gas-liquid separator through the four-way valve; the gas phase CO2 is mixed with the gas phase CO2 to flow into a first heat exchanger to be heated and finally flows into an absorber
