Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0042] Figure 1 This is a schematic diagram of the turbocharging system for a hydrogen internal combustion engine provided in an embodiment of the present invention. See also... Figure 1The turbocharging system 100 of the hydrogen internal combustion engine includes a hydrogen pump 1, a turbine 2, a compressor 3, a connecting shaft 4, and a control module 5. The hydrogen pump 1 is connected to the inlet of the turbine 2 via a pipeline to supply hydrogen to the turbine 2. The outlet of the turbine 2 is connected to the inlet of the combustion chamber 200 of the hydrogen internal combustion engine via a pipeline. The impeller of the turbine 2 is connected to the compressor 3 via the connecting shaft 4. The turbine 2 drives the compressor 3 to work by rotating the impeller and delivers hydrogen to the combustion chamber 200. The outlet of the compressor 3 is connected to the inlet of the combustion chamber 200 via a pipeline to pressurize the air and output the pressurized air to the combustion chamber 200. The control module 5 is electrically connected to the hydrogen pump 1 to acquire the operating parameters of the hydrogen internal combustion engine in real time and adjust the output power of the hydrogen pump 1 according to the operating parameters.

[0043] Specifically, during operation, a hydrogen internal combustion engine requires mixing a certain amount of hydrogen with air before combustion in the combustion chamber 200. To improve combustion efficiency and meet power requirements, a large amount of air is needed during combustion; therefore, the air needs to be pressurized first to increase the intake air volume into the combustion chamber 200. Existing hydrogen internal combustion engines utilize exhaust gas for air pressurization, but this method is ineffective, difficult to control, and may damage the equipment. Existing hydrogen internal combustion engines lack a suitable air pressurization system. The pressurization system 100 for a hydrogen internal combustion engine provided by this invention can precisely control the air pressure ratio, providing the appropriate amount of air to the engine. This pressurization system 100 includes a hydrogen pump 1, a turbine 2, a compressor 3, a connecting shaft 4, and a control module 5. The hydrogen pump 1 is primarily used to perform work on the hydrogen, delivering high-pressure hydrogen to the turbine 2. The outlet of turbine 2 is connected to the inlet of combustion chamber 200 via a pipeline, allowing hydrogen gas to be transported to combustion chamber 200 for combustion. As high-pressure hydrogen gas passes through turbine 2, its own kinetic and pressure potential energy drives the turbine impeller to rotate. Since turbine 2 is connected to compressor 3 via connecting shaft 4, the rotation of turbine impeller 2 drives compressor 3 to pressurize the incoming air. The outlet of compressor 3 is also connected to the inlet of combustion chamber 200 via a pipeline, allowing the pressurized air to mix with hydrogen before entering combustion chamber 200 for combustion. Utilizing the energy of hydrogen itself to pressurize air eliminates the need for additional pressurization devices, thus making efficient use of resources and reducing waste. Furthermore, the pressurization system 100 of this hydrogen internal combustion engine is equipped with a control module 5, which is electrically connected to hydrogen pump 1 and can control the output power of hydrogen pump 1 according to the needs of the hydrogen internal combustion engine. The control module 5 can reuse the control unit of the hydrogen internal combustion engine. The control module 5 can adjust the output power of the hydrogen pump 1 in real time according to the operating parameters of the hydrogen internal combustion engine, thereby adjusting the air-hydrogen mixing ratio. The operating parameters of the hydrogen internal combustion engine may include information such as engine speed, load, intake pressure, and the temperature and pressure of the combustion chamber 200, which are not specifically limited in this embodiment. When the output power of the hydrogen pump 1 is higher, the hydrogen flow rate delivered to the compressor 3 is greater, and the impeller rotation frequency of the turbine 2 also increases, thus making the compressor 3 more efficient at pressurizing air. The control module 5 can acquire the operating parameters of the hydrogen internal combustion engine in real time and adjust the output power of the hydrogen pump 1 accordingly, achieving feedback regulation of the hydrogen internal combustion engine's pressurization system 100, further improving the air pressure ratio, combustion efficiency, and output power of the hydrogen internal combustion engine.

[0044] The turbocharging system for a hydrogen internal combustion engine provided in this invention includes a hydrogen pump, a turbine, a compressor, and a connecting shaft. The hydrogen pump performs work on hydrogen, delivering high-pressure hydrogen to the turbine. The high-pressure hydrogen drives the turbine impeller to rotate and is then delivered to the combustion chamber. The impeller and compressor are connected via the connecting shaft. The rotation of the impeller driven by the high-pressure hydrogen drives the compressor to work, thereby pressurizing the air. Utilizing the kinetic and pressure potential energy of the high-pressure hydrogen itself to pressurize the air results in better pressurization and more efficient use of resources, eliminating the need for other energy sources. Furthermore, the control module can acquire the operating parameters of the hydrogen internal combustion engine in real time, thereby adjusting the output power of the hydrogen pump in a timely manner. This allows for feedback regulation of the turbocharging system, more precise adjustment of the hydrogen-to-air ratio, and more reasonable control of the air pressure ratio, improving the output efficiency of the hydrogen internal combustion engine.

[0052] Specifically, a first pressure sensor 9 can be installed between the hydrogen storage tank 8 and the turbine 2. The first pressure sensor 9 is mainly used to obtain the first pressure information of the hydrogen supplied from the hydrogen storage tank 8 to the hydrogen pump 1. A second pressure sensor 10 can also be installed at the outlet of the pressure regulator 6. The second pressure sensor 10 is mainly used to obtain the second pressure information of the hydrogen output by the pressure regulator 6. The second pressure sensor 10 is located on the pipeline between the pressure regulator 6 and the combustion chamber 200, and can obtain the second pressure information of the hydrogen after adjustment by the pressure regulator 6.

[0053] Optionally, based on the above embodiments, see also... Figure 5The turbocharging system 100 of the hydrogen internal combustion engine also includes a third pressure sensor 11 and a temperature sensor 12; the third pressure sensor 11 is located inside the combustion chamber 200 and is used to obtain the third pressure information inside the combustion chamber 200; the temperature sensor 12 is located inside the combustion chamber 200 and is used to obtain the temperature information inside the combustion chamber 200.

[0054] Specifically, a third pressure sensor 11 and a temperature sensor 12 can be installed in the combustion chamber. The third pressure sensor 11 can acquire the third pressure information of the combustion chamber 200 in real time, and the temperature sensor 12 can acquire the temperature information of the combustion chamber 200 in real time. By using the third pressure information and temperature information of the combustion chamber 200, it is possible to determine whether the combustion of air and hydrogen in the combustion chamber is complete, and whether the exhaust gas after combustion is discharged in a timely manner, thereby adjusting the flow rate of air and hydrogen entering the combustion chamber 200.

[0055] Optionally, based on the above embodiments, see also... Figure 5 The control module 5 is electrically connected to the pressure regulator 6, the flow control valve 7, the first pressure sensor 9, the second pressure sensor 10, the third pressure sensor 11, and the temperature sensor 12, respectively. The control module 5 is used to adjust the output power of the hydrogen pump 1, the opening degree of the pressure regulator 6, and the opening degree of the flow control valve 7 according to the first pressure information, the second pressure information, the third pressure information, and the temperature information.

[0056] Specifically, the control module 5 is also electrically connected to the pressure regulator 6, the flow control valve 7, the first pressure sensor 9, the second pressure sensor 10, the third pressure sensor 11, and the temperature sensor 12. The control module 5 can receive the first pressure information acquired by the first pressure sensor 9, the second pressure information acquired by the second pressure sensor 10, the third pressure information acquired by the third pressure sensor 11, and the temperature information acquired by the temperature sensor 12. Then, it adjusts the output power of the hydrogen pump 1, the opening degree of the pressure regulator 6, and the opening degree of the flow control valve 7 based on the first pressure information acquired by the first pressure sensor 9, the third pressure information in the combustion chamber 200 acquired by the third pressure sensor 11 and the temperature information acquired by the temperature sensor 12.

When the gas combustion in the combustion chamber 200 is incomplete, the control module 5 can increase the output power of the hydrogen pump 1, thereby causing the compressor 3 to increase the pressure on the air, increasing the amount of air entering the combustion chamber 200. The control module 5 can also reduce the opening of the pressure regulator 6 to lower the hydrogen pressure and reduce the amount of hydrogen entering the combustion chamber 200, ensuring complete combustion of the gas in the combustion chamber. By adjusting the output power of the hydrogen pump 1 and the opening of the pressure regulator 6, the air-to-hydrogen ratio can be adjusted in a timely manner to ensure the highest combustion efficiency in the combustion chamber 200 and prevent resource waste. The control module 5 can also adjust the opening of the flow control valve 7 based on the third pressure and temperature information to control the flow rate of air and hydrogen entering the combustion chamber 200, further controlling the flow rate of air and hydrogen entering the combustion chamber 200. For example, when the power demand of the hydrogen internal combustion engine is high, the opening of the flow control valve 7 can be appropriately increased to allow more gas to enter the combustion chamber 200, ensuring the output power of the hydrogen internal combustion engine. The control module 5 can also independently adjust the flow rate of hydrogen from the hydrogen storage tank 8 to the hydrogen pump 1 based on the first pressure information obtained from the first pressure sensor 9, and independently adjust the opening of the pressure regulator 6 based on the second pressure information obtained from the second pressure sensor 10. To achieve precise control of each device, thereby improving the accuracy of the entire system.

[0057] Optional, Figure 6 This is a schematic diagram of a turbocharging system for another hydrogen internal combustion engine provided in an embodiment of the present invention. Based on the above embodiments, see... Figure 6 The turbocharging system 100 of the hydrogen internal combustion engine also includes an air filter 13; the outlet of the air filter 13 is connected to the inlet of the compressor 3 through a pipeline, and is used to filter the air entering the compressor 3.

[0058] Specifically, the turbocharging system 100 of the hydrogen internal combustion engine is also equipped with an air filter 13.

Based on the above embodiments, see... Figure 7 The turbocharging system 100 of the hydrogen internal combustion engine also includes a compressor 14; the air inlet of the compressor 14 is connected to the air outlet of the compressor 3 through a pipeline, and the air outlet is connected to the air inlet of the combustion chamber 100 through a pipeline; the compressor 14 is used to perform secondary turbocharging on the air output by the compressor 3 when the pressure of the air output by the compressor 3 is less than the preset pressure.

[0060] Specifically, the turbocharging system 100 of the hydrogen internal combustion engine also includes a compressor 14. The compressor 14 is located on the pipeline between the compressor 3 and the combustion chamber 200, and is mainly used for secondary turbocharging of the air after turbocharging by the compressor 3. When the hydrogen internal combustion engine requires a large amount of power, a large amount of hydrogen and air is needed. The ability of high-pressure hydrogen to drive the turbine 2 impeller and thus drive the compressor 3 to turbocharge the air is limited; the compressor 3 alone cannot meet the needs of the hydrogen internal combustion engine under extreme conditions. By installing the compressor 14 at the rear end of the compressor 3, when the air pressure after turbocharging by the compressor 3 is lower than a preset pressure, the compressor 14 performs secondary turbocharging of the air after turbocharging by the compressor 3 to meet the power requirements of the hydrogen internal combustion engine.

[0061] The turbocharging system for a hydrogen internal combustion engine provided in this invention uses high-pressure hydrogen to drive an impeller, which in turn drives a compressor via a connecting shaft to pressurize air. A compressor is also included to address situations where the compressor cannot meet the engine's demands in extreme conditions. Utilizing the kinetic and pressure potential energy of the high-pressure hydrogen itself to pressurize air results in better performance and more efficient resource utilization, eliminating the need for other energy sources. Furthermore, the control module can acquire real-time operating parameters of the hydrogen internal combustion engine, allowing for timely adjustments to the hydrogen pump's output power, pressure regulator, and flow control valve opening. This feedback regulation of the turbocharging system enables more precise control of the hydrogen-to-air ratio and the air pressure ratio, thereby improving the engine's efficiency.
