Abstract
The article presents a study of the possibility for replacing traditional hydrocarbon fuel used in the automotive internal combustion engine with cryogenic liquids or cryogenic working fluid. The use of cryogenic working fluid makes such a vehicle safe to operate. The comparison of calculated cycles and operating flows of cryogenic power plants is made. The plant with cryogenic balloon and turboexpander and the following optimum parameters – the smallest refrigerant consumption (0.024 kg/s), the highest specific refrigerating capacity (444 kJ/kg, and energy recovery coefficient of 3.2 % – is proved to be the most effective. The power plant in question provides the expansion of liquid nitrogen or liquid air due to the thermal energy of the environment during gasification of liquid nitrogen for the production of mechanical energy power, which can later be used to drive auxiliary devices of the car such as: electric generator and compressor steam compression refrigeration machine or as the main engine of the car. Another important aspect of the using cryogenic working fluid instead of traditional hydrocarbon fuel is the zero emission of pollutants into the environment, which is very important for megacities.
