Description

Technical Field

[0001] This invention relates to the field of engine combustion, and in particular to an intelligent heating system and control method for ammonia fuel in an ammonia-hydrogen fusion power unit. Background Technology

[0002] Environmental protection has become a common concern for all countries due to the massive carbon emissions caused by over-reliance on fossil fuels. In the future, the use of ammonia and hydrogen fuels in internal combustion engines will have significant environmental and sustainability advantages. These two fuels primarily produce water vapor during combustion, with virtually no harmful emissions, thus potentially reducing air pollution and the greenhouse effect. Furthermore, ammonia and hydrogen can be produced from renewable energy sources, thereby reducing dependence on finite fossil fuels and improving the sustainability of energy supply. Their high efficiency and lightweight properties also promise to improve vehicle performance and operational efficiency, thus holding broad application prospects in the future of internal combustion engine technology.

[0003] Hydrogen can be produced through various methods, offering energy diversity and the potential to reduce reliance on traditional fossil fuels for internal combustion engines. Furthermore, hydrogen refueling is faster than charging electric vehicles, similar to refueling a traditional gasoline-powered car. Hydrogen fuel has a high energy density when burned, thus providing powerful performance. Additionally, hydrogen combustion produces only water vapor, emitting no harmful gases or greenhouse gases, thus helping to reduce environmental pollution and its impact on climate change.

[0004] Ammonia can be produced using renewable energy sources such as wind and solar power, thereby reducing dependence on finite fossil fuels and promoting energy sustainability. Compared to hydrogen, ammonia is easier to store and transport, and can be stored in relatively conventional facilities without requiring extremely high pressure conditions. Furthermore, ammonia fuel has a relatively high energy density, meaning it can provide powerful combustion, contributing to improved efficiency and performance of internal combustion engines. In addition, ammonia combustion primarily produces nitrogen and water vapor, emitting almost no harmful gases, thus helping to reduce air pollution and greenhouse gas emissions, further promoting environmental protection. Summary of the Invention

[0005] To address the problems caused by the high latent heat of vaporization of ammonia, including pressure drop in the ammonia storage tank, reduced ammonia flow rate, and low initial ammonia temperature, which lead to combustion difficulties, and to effectively recover the residual heat of the internal combustion engine exhaust while heating both ammonia and intake air to improve energy utilization efficiency and reduce pollutant emissions, thereby achieving efficient and clean combustion in the internal combustion engine, this invention provides an intelligent ammonia fuel heating system and control method for an ammonia-hydrogen fusion power unit. By incorporating a water bath heating and cooling control device, the system maintains stable pressure in the ammonia storage tank through heating and cooling, ensuring stable ammonia flow rate and ammonia fuel temperature, thus achieving efficient and clean combustion and stable operation of the internal combustion engine under different load conditions.

[0006] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0007] An intelligent heating system for ammonia fuel in an ammonia-hydrogen fusion power plant includes a heating control system, a cooling control system, an electric heating control system, an ammonia supply system, a hydrogen supply system, a combustion system, an intake system, and an exhaust system.

[0008] The heating control system is used to heat ammonia gas;

[0009] The cooling control system is used to cool ammonia gas;

[0010] The electric heating system is used to provide heat to the ammonia supply system;

[0011] The ammonia supply system includes an ammonia storage tank, an ammonia pressure reducing valve, an ammonia filter, and an ammonia injection valve. The outlet of the ammonia storage tank is connected to the ammonia pressure reducing valve, the outlet of the ammonia pressure reducing valve is connected to the ammonia filter, and the ammonia filter is connected to the ammonia injection valve via a pipeline. The ammonia injection valve is used to inject ammonia and is located inside the inlet thin-walled cylinder.

[0012] The hydrogen supply system includes a hydrogen storage tank, a hydrogen pressure reducing valve, a hydrogen filter, a flashback valve, and a hydrogen injection valve. The outlet of the hydrogen storage tank is connected to the hydrogen pressure reducing valve, the outlet of the hydrogen pressure reducing valve is connected to the hydrogen filter, the hydrogen filter is connected to the flashback valve, the flashback valve is connected to the hydrogen injection valve through a pipeline, and the hydrogen injection valve is installed in the jet chamber.

[0013] The combustion system includes a jet chamber, a spark plug, a main combustion chamber, and a piston; the main combustion chamber is connected to both the intake system and the exhaust system, and the jet chamber is connected to the main combustion chamber through at least one jet nozzle; the ignition electrode of the spark plug is installed next to the hydrogen injection valve inside the jet chamber.

[0014] The intake system includes an intake thin-walled cylinder and an intake valve; the intake valve is located at the outlet end of the intake thin-walled cylinder and is used to control the intake of the main combustion chamber.

[0015] The exhaust system includes an exhaust thin-walled cylinder and an exhaust valve; the exhaust valve is located at the inlet end of the exhaust thin-walled cylinder and is used to control the exhaust gas from the main combustion chamber.

[0016] In the above scheme, the heating control system includes an exhaust thin-walled cylinder, a circulating water fan, a second circulating water pump, and a water storage tank; the liquid absorbs the heat of the exhaust gas through the intake thin-walled cylinder, and enters the water storage tank through the circulating fan and the second circulating water pump to heat the ammonia tank inside the water storage tank; a water bath temperature sensor is installed inside the water storage tank.

[0017] In the above scheme, the cooling control system includes an air intake thin-walled cylinder, a first solenoid valve, a second solenoid valve, and a first circulating water pump; after the first solenoid valve and the second solenoid valve are opened, the liquid is cooled by the air intake and ammonia gas inside the air intake thin-walled cylinder, and then the flow rate is regulated by the first circulating water pump before entering the water storage tank.

[0018] In the above scheme, the heating control system controls the water bath temperature sensor, the first solenoid valve, the second solenoid valve, the first circulating water pump, the second circulating water pump, and the electric heating wire via the CAN bus.

[0019] In the above scheme, the water bath temperature sensor is used to monitor the water bath temperature of the water storage tank and send the water bath temperature signal to the heating controller.

[0020] In the above scheme, the heating control system receives the temperature signal from the water bath temperature sensor, compares it with the preset temperature value, and determines whether to activate the electric heating wire.

[0021] The heating control system controls the flow rate of the second circulating water pump. The heating controller adjusts the flow rate of the second circulating water pump based on the load rate of the ammonia-hydrogen jet ignition engine and the water bath temperature signal.

[0022] The cooling control system controls the flow rate of the circulating water pump, and the heating controller determines the status of the first solenoid valve and the second solenoid valve and adjusts the flow rate of the first circulating water pump based on the load rate of the ammonia-hydrogen jet ignition engine and the water bath temperature signal.

[0023] In the above scheme, the preset temperature value is 90℃.

[0024] The control method for the intelligent heating system of ammonia fuel in an ammonia-hydrogen jet ignition engine includes the following steps:

[0025] When the ammonia-hydrogen jet ignition engine is running, the heating control system starts and receives the temperature signal from the water bath temperature sensor.

[0026] If the water bath temperature exceeds the predetermined value, the electric heating wire will be turned off. At this time, the circulating water is heated by the exhaust gas temperature, while the high latent heat of vaporization of ammonia and the cooling effect of the intake air are used to reduce the temperature of the circulating water. In addition, the circulating water in the cooling control system is used to heat the ammonia and the intake air. Under these circumstances, the flow rate of the second circulating water pump in the heating control system will decrease, while the first and second solenoid valves of the cooling system will be opened, and the flow rate regulated by the first circulating water pump will increase.

[0027] If the water bath temperature is lower than the predetermined value, and the engine load rate is between 0% and 25%, the electric heating wire will be activated. During heating, if the water bath temperature is not higher than 80°C, the electric heating wire will continue to heat. If the water bath temperature is between 80°C and 90°C, heating is achieved by relying on the electric heating wire and the residual heat of the exhaust gas to stabilize and control the water bath temperature. During this process, the first solenoid valve, the second solenoid valve, and the first circulating water pump will be opened. The high latent heat of vaporization of ammonia and the cooling effect of the intake air are used to stabilize and control the water bath temperature. At the same time, the circulating water in the cooling control system is used to heat the ammonia and the intake air. In this case, the flow rate of the heating system circulating water pump will increase, while the flow rate of the cooling control system circulating water pump will decrease.

[0028] If the water bath temperature is lower than the predetermined value, and the engine load rate is between 25% and 75%, the electric heating wire will be activated. During heating, if the water bath temperature does not exceed 70°C, the electric heating wire will continue heating. If the water bath temperature is between 70°C and 90°C, heating will be achieved using the electric heating wire and the residual heat of the exhaust gas, thereby stabilizing and controlling the water bath temperature. During this process, the first solenoid valve, the second solenoid valve, and the first circulating water pump will be opened, utilizing the high latent heat of vaporization of ammonia and the cooling effect of the intake air to stabilize and control the water bath temperature, while simultaneously using the circulating water in the cooling control system to heat the ammonia and the intake air. In this situation, the flow rate of the second circulating water pump in the heating control system will increase, and the flow rate of the first circulating water pump in the cooling control system will also increase.

[0029] If the water bath temperature is lower than the predetermined value, and the engine load rate is between 75% and 100%, the electric heating wire will be activated. During heating, if the water bath temperature does not exceed 60°C, the electric heating wire will continue heating. If the water bath temperature is between 60°C and 90°C, heating will be achieved using the electric heating wire and the residual heat of the exhaust gas, thereby stabilizing and controlling the water bath temperature. During this process, the first solenoid valve, the second solenoid valve, and the first circulating water pump will be opened, utilizing the high latent heat of vaporization of ammonia and the cooling effect of the intake air to stabilize and control the water bath temperature, while simultaneously using the circulating water in the cooling control system to heat the ammonia and the intake air. In this situation, the flow rate of the second circulating water pump in the heating control system will increase, and the flow rate of the first circulating water pump in the cooling control system will also increase.

[0030] Beneficial effects:

[0031] 1. This invention adds an ammonia storage tank water bath heating and cooling control device to the existing jet ignition engine. By heating and cooling the ammonia storage tank through a water bath, the internal pressure and temperature of the ammonia are controlled, ensuring stable ammonia outlet pressure and constant injection flow. This method addresses the problems of difficult ignition, long ignition delay, and slow combustion speed caused by the combustion inertia of ammonia fuel through intake air heating. Simultaneously, during the combustion process of the internal combustion engine, the system absorbs part of the exhaust gas waste heat through circulating water in a thin-walled cylinder, achieving the recovery and reuse of exhaust gas energy waste heat. However, this does not significantly reduce the temperature of the high-temperature exhaust gas, nor does it have a significant impact on the engine aftertreatment device. Furthermore, by introducing an electric heating wire water bath heating device, the system can actively heat and raise the temperature of the ammonia storage tank, reducing dependence on the exhaust gas waste heat during cold starts and idling conditions, thereby ensuring the efficient operation of the aftertreatment device. In this invention, the engine energy is provided by hydrogen and ammonia: hydrogen is injected into the jet chamber to form a rich mixture, which is ignited by the spark plug, and then the ammonia injected into the intake manifold is ignited through the jet nozzle, so as to achieve stable operation of the ammonia-hydrogen jet ignition engine under different load rates.

[0032] 2. This invention uses an intelligent heating device to heat and cool the ammonia storage tank in a water bath, achieving efficient and clean combustion in the ammonia-hydrogen jet ignition engine and reducing the emission of unburned ammonia-hydrogen.

[0033] 3. The control method of this invention can select an appropriate heating mode according to different engine load rates and water bath temperatures. When the water bath temperature rises, intake air cooling is used to ensure that ammonia fuel enters the cylinder for combustion at a suitable temperature and constant flow rate, improving ignition difficulties, ignition delays, slow combustion rates, and reducing excessive unburned ammonia emissions caused by low ammonia reactivity. This invention can achieve efficient and clean combustion in ammonia-hydrogen jet ignition engines, while effectively recovering latent heat from the intake air and waste heat from the exhaust, demonstrating good economic benefits and application prospects.

[0058] The water bath temperature sensor 26 is used to monitor the water bath temperature of the water storage tank 23 outside the ammonia tank and send the water bath temperature signal to the heating controller.

[0059] The heating controller receives water bath temperature signals from the water storage tank 23 at different load rates and detects whether the preset temperature is exceeded. If it is exceeded, the heating controller will turn off the heating of the electric heating wire 24 and start the second circulating water pump 21 of the heating control system for flow regulation.

[0064] If the water bath temperature is higher than the predetermined value, the electric heating wire 24 will be turned off. At this time, the residual heat of the exhaust gas is used to heat the circulating water, while the high latent heat of vaporization of ammonia and the cooling effect of the intake air are used to reduce the temperature of the circulating water. In addition, the circulating water in the cooling control system is used to heat the ammonia and the intake air.

During heating, if the water bath temperature is not higher than 80°C, the electric heating wire 24 will continue to heat. If the water bath temperature is between 80°C and 90°C, heating will be achieved by relying on the electric heating wire 24 and the residual heat of the exhaust gas, thereby stabilizing and controlling the water bath temperature. During this process, the first solenoid valve 18, the second solenoid valve 19, and the first circulating water pump 20 will be opened.

The control method for the intelligent ammonia fuel heating system of the ammonia-hydrogen jet ignition engine according to any one of claims 1-4, characterized in that, Includes the following steps: When the ammonia-hydrogen jet ignition engine is running, the heating control system starts and receives the temperature signal from the water bath temperature sensor (26); If the water bath temperature is higher than the predetermined value, the electric heating wire (24) will be turned off; at this time, the residual heat of the exhaust gas is used to heat the circulating water, while the high latent heat of vaporization of ammonia and the cooling effect of the intake air are used to reduce the temperature of the circulating water; in addition, the circulating water in the cooling control system is used to heat the ammonia and the intake air; under these circumstances, the flow rate of the second circulating water pump (21) in the heating control system will decrease, the first solenoid valve (18) and the second solenoid valve (19) will be opened, and the flow rate of the first circulating water pump (20) in the cooling control system will increase; If the water bath temperature is lower than the predetermined value and the engine load rate is between 0% and 25%, the electric heating wire (24) will be activated. During heating, if the water bath temperature is not higher than 80°C, the electric heating wire (24) will continue to heat. If the water bath temperature is between 80°C and 90°C, the electric heating wire (24) and the residual heat of the exhaust gas will be used to heat the water bath, thereby stabilizing the water bath temperature. During this process, the first solenoid valve (18), the second solenoid valve (19), and the first circulating water pump (20) will be opened. The high latent heat of vaporization of ammonia and the cooling effect of the intake air will be used to stabilize the water bath temperature. At the same time, the circulating water in the cooling control system will be used to heat the ammonia and the intake air. In this case, the flow rate of the second circulating water pump (21) of the heating system will increase, while the flow rate of the first circulating water pump (20) of the cooling control system will decrease. If the water bath temperature is lower than the predetermined value and the engine load rate is between 25% and 75%, the electric heating wire (24) will be activated. During heating, if the water bath temperature is not higher than 70°C, the electric heating wire (24) will continue to heat. If the water bath temperature is between 70°C and 90°C, the electric heating wire (24) and the residual heat of the exhaust gas will be used for heating to stabilize the water bath temperature. During this process, the first solenoid valve (18), the second solenoid valve (19), and the first circulating water pump (20) will be opened to stabilize the water bath temperature by utilizing the high latent heat of vaporization of ammonia and the cooling effect of the intake air. At the same time, the circulating water in the cooling control system will be used to heat the ammonia and the intake air. In this case, the flow rate of the second circulating water pump (21) in the heating control system will increase, and the flow rate of the first circulating water pump (20) in the cooling control system will also increase. If the water bath temperature is lower than the predetermined value and the engine load rate is between 75% and 100%, the electric heating wire (24) will be activated. During heating, if the water bath temperature is not higher than 60°C, the electric heating wire (24) will continue to heat. If the water bath temperature is between 60°C and 90°C, the electric heating wire (24) and the residual heat of the exhaust gas will be used to heat the water bath, thereby stabilizing the water bath temperature. During this process, the first solenoid valve (18), the second solenoid valve (19), and the first circulating water pump (20) will be opened. The high latent heat of vaporization of ammonia and the cooling effect of the intake air will be used to stabilize the water bath temperature, and the circulating water in the cooling control system will be used to heat the ammonia and the intake air. In this case, the flow rate of the second circulating water pump (21) in the heating control system will increase, and the flow rate of the first circulating water pump (20) in the cooling control system will also increase.
