As shown in FIG. 1, the specific implementation of the new energy vehicle and the novel gas power system of the present invention is as follows: A liquid storage tank 1, such as a liquid nitrogen bottle, whose liquid outlet is connected to the liquid gas delivery line π. The liquid gas delivery line 17 is sequentially connected to the electric shutoff valve 21, the infusion pump 3, the throttle valve 4 (expansion valve), the shutoff valve 63, the intake port of the air conditioner heat exchanger 5, and the intake port of the exhaust gas heat exchanger 7. . The primary gas delivery line 18 is connected to the air outlet of the air conditioner heat exchanger 5, the shutoff valve 62, the air inlet of the exhaust heat exchanger 7, and the exhaust gas heat exchanger. The air outlet of 7 is connected to the air inlet of the metal fuel burner 8 through a primary gas delivery line 18. A metal fuel conveyor 15 is mounted above the burner 8 and is insulated from the burner 8 by an insulating material. The gas outlet of the burner 8 is connected to the high pressure gas cylinder 11 through a gas pipe provided with a check valve 14 (check valve). The high pressure gas cylinder 11 is insulated with an insulating material. The high-pressure gas cylinder 1 is connected to the air motor 9 through a gas pipe, and the gas pipe is provided with a pressure regulating valve 13 , a ball valve 12 or a butterfly valve 12 , and an electric shut-off valve 22 .

In the present embodiment, the ball valve 12 or the butterfly valve 12 is coupled to the pedal throttle of the automobile. The air outlet of the air motor 9 is connected to the circulating gas delivery line 19 and is connected to the air inlet of the shutoff valve 65 and the exhaust heat exchanger 7. At the same time, a shut-off valve 61 is attached to the connecting line of the circulating gas delivery line 19 and the air inlet of the air-conditioning heat exchanger 5. The connecting line of the circulating gas delivery line 19 and the air outlet of the air conditioner heat exchanger 5 is provided with a shutoff valve 64 and is connected to the intake port of the exhaust gas heat exchanger 7.

The circulating gas delivery line 19 connects the gas outlet of the exhaust gas heat exchanger 7 and the gas inlet of the gas compressor 10. The gas compressor 10 gas outlet is connected to the filter oil tank 20 by the circulating gas delivery line 19 and then connected to the gas inlet of the burner 8. The exhaust gas heat exchanger 7 is provided with a pressure relief valve 16 on the circulating gas delivery line 19 connected to the gas outlet to discharge excess exhaust gas.

The working sequence of the new energy vehicle gas power system of the present invention is: opening the main switch of the automobile gas power system to start the vehicle. At this time, the electric shut-off valve 21 on the liquid gas delivery line 7 to which the liquid nitrogen storage tank 1 is connected, and the electric shut-off valve 22 on the intake pipe connected to the air motor 9 are opened. When the ignition switch is pressed once, the metal fuel conveyor 15 starts to deliver the metal fuel to the burner 8, the electric ignition delay starts, and the infusion pump 3 connected to the liquid gas delivery line 7 starts to work. The liquid nitrogen gas enters the shutoff valve 63, the air conditioner heat exchanger 5 inlet port and the exhaust gas heat exchanger 7 inlet port through the throttle valve 4, respectively. Nitrogen enters the exhaust gas heat exchanger through the shut-off valve 62 after the endothermic expansion in the air-conditioning heat exchanger 5, and the heat exchange is continued. The shut-off valves 62, 63 can be used for cooling in summer and closed in winter.

The nitrogen from the gas outlet of the exhaust gas heat exchanger 7 enters the inlet of the burner 8 through the primary gas delivery line 18. The metal fuel, for example, the aluminothermic agent is ignited and starts to burn, releasing a large amount of heat, causing the nitrogen gas passing through the burner 8 to become a high-temperature and high-pressure gas, and entering the high-pressure gas cylinder 11 through the gas supply line and the check valve 14, the burner 8 The gas cylinder 11 is connected to the gas pipeline, and the two bodies are also in contact with each other, and the waste heat generated by the burner 8 is fully utilized to maintain the nitrogen in the gas cylinder 11 in a high temperature and high pressure state.

Start the car: Press the clutch and step on the throttle. As the throttle is depressed, the ball valve 12 on the air intake pipe of the air motor 9 is gradually opened. The high temperature and high pressure gas in the air tank 11 enters the pneumatic horse through the gas pipe. Up to 9, the air motor 9 starts to rotate, the clutch is released, and the car starts to drive. At this time, the pressure regulating valve 13 installed on the gas pipe between the high pressure gas cylinder 11 and the air motor 9 has adjusted the outlet pressure. After the work, the high temperature and low pressure gas (exhaust gas) from the air outlet of the air motor 9 can enter the air conditioner heat exchanger 5 through the shutoff valve 64 in the winter, and then enter the exhaust gas heat exchanger 7. In the summer, the shut-off valves 61, 64 of the exhaust gas entering and exiting the air-conditioning heat exchanger 5 are turned off, and the exhaust gas is directly introduced into the shut-off valve 65 of the exhaust gas heat exchanger 7, and the shut-off valve 65 is closed in winter. The low-temperature low-pressure gas (exhaust gas) from the exhaust gas heat exchanger 7 enters the gas compressor 10, and after the exhaust gas is pressurized, the circulating gas delivery line 19 filters the oil through the filter oil tank 20, and then is sent to the burner 8 to raise and raise the pressure. Realize the recycling of exhaust gas. When the exhaust pressure reaches a certain value, the pressure relief valve 16 opens to remove excess gas.

In the driving process of the vehicle of the present invention, when the temperature of the burner 8 is lower than the set value, the ignition switch of the burner 8 is pressed, fuel is added, and the temperature is increased. When the fuel of the burner 8 is used up, the combustion residue is taken out and the fuel is replaced in time. The residual fuels of metal fuels such as aluminothermic burners are iron and aluminum oxide, which are completely reusable resources that can be directly recycled to steel mills and aluminum smelters. Preservation of combustion residues can be used to exchange metal fuels.

Among the metal fuels used in the present invention, two kinds of light metals, magnesium and aluminum, are typical representatives, and they have many advantages: First, the carbon-free cleaning, the fuel does not release carbon dioxide, sulfur dioxide and other greenhouse gases and harmful substances when burned. Second, the fuel has a high calorific value, and the fuel is small and refined, which is convenient for transportation, use and storage. Third, it can be used forever. After the metal fuel is processed, it can be reused many times without wasting resources. There is little or no industrial waste. Fourth, safety is good. Compared with coal, the underground fuel production of metal fuel is relatively safe, and there is no pollution accident compared with nuclear fuel. The fifth is to save resources, and the saved fossil resources can be converted to other uses, such as producing higher value chemical products. Sixth, the production technology is mature, and the process of manufacturing magnesium-aluminum industrial products by electrolysis is simple and the technology is quite mature. Seven is rich in resources. Magnesium-aluminum is the most abundant metal element on earth. Metal magnesium can be made from electrolytically molten magnesium chloride. Magnesium chloride is usually taken from seawater, but seawater is inexhaustible.

The gas that can be used as a power medium in the present invention is an industrial gas such as liquid air, liquid oxygen, liquid nitrogen or liquid carbon dioxide. The above industrial gases are widely produced and used in various places, and they are widely available. Unlike petrochemical fuels such as gasoline and diesel, they are concentrated in petroleum system production. Industrial gases come from the air and are released into the air after use, but only the recycling of the air without any pollution.
