[0039] The following further describes the present invention in detail with specific embodiments, and these embodiments should not be construed as limiting the scope claimed by the present invention.

[0040] The present invention aims to solve the following technical problems: optimizing the hydrogen incorporation method to ensure uniform mixing of hydrogen and air, improving combustion efficiency, and reducing pollutant gas emissions; heating the solid-state hydrogen storage device with the waste heat of the exhaust gas to enhance the hydrogen release efficiency and stability of the solid-state hydrogen storage device and reduce the dependence on electric heating; designing an efficient air-cooling and water-cooling combined heat exchange system to improve the utilization rate of the exhaust gas waste heat and stabilize the working state of the solid-state hydrogen storage device; enhancing the combustion efficiency of the diesel-hydrogen dual-fuel internal combustion engine to achieve energy conservation and emission reduction and strengthen the engine power output.

[0041] Figure 1 It is a schematic structural diagram of a diesel-hydrogen blended internal combustion engine system provided by an embodiment of the present invention; Figure 2 It is a schematic structural diagram of a heat exchanger involved in an embodiment of the present invention; Figure 3 It is a schematic structural diagram of a solid-state hydrogen storage device involved in an embodiment of the present invention.

[0042] As Figure 1 shown, the diesel-hydrogen blended internal combustion engine system provided by an embodiment of the present invention includes an internal combustion engine main body, a hydrogen nozzle 1, a solid-state hydrogen storage device 2, and a heat exchanger 3.

[0043] Among them, the internal combustion engine main body can be selected from conventional diesel internal combustion engines in the field. Exemplarily, the internal combustion engine main body may include conventional mechanical structures such as a turbocharger, an intercooler, an intake manifold, a diesel nozzle, a cylinder, an exhaust pipe, etc. In the diesel-hydrogen blended internal combustion engine system of this embodiment, the turbocharger is the core device that provides high-pressure air for the internal combustion engine. The supercharged air enters the intake manifold through a throttle valve and mixes with the hydrogen from the hydrogen nozzle 1 to improve the combustion efficiency. The intake manifold, as the mixing channel for hydrogen and supercharged air, connects the throttle valve and the intake ports of each cylinder of the internal combustion engine. The supercharged air and hydrogen are fully mixed downstream in the intake manifold and then enter the cylinder.

[0044] The hydrogen nozzle 1 is arranged downstream of the intake manifold of the internal combustion engine main body and close to the cylinder intake port for injecting hydrogen into the intake manifold. It should be noted that the number of hydrogen nozzles 1 should not be greater than the number of cylinders. In a specific implementation manner, one hydrogen nozzle 1 is correspondingly arranged for each cylinder. The hydrogen nozzle 1 can be arranged along the air flow direction in the intake manifold so that the hydrogen nozzle 1 can inject hydrogen along the air flow direction. The angle between the hydrogen nozzle 1 and the inner wall of the intake manifold along the air flow direction can be 30° to 60°, and the injection pressure can be 1.5 to 3 MPa. These settings are used to ensure full mixing of hydrogen and air during the intake process.

[0045] Specifically, a hydrogen nozzle 1 is arranged at a downstream position (near the cylinder intake port) of the internal combustion engine intake manifold to ensure that hydrogen can quickly and fully mix with air; the hydrogen nozzle 1 is set in the same direction as the air flow direction, and the injection angle is controlled within the range of 30° - 60°, which can effectively reduce turbulence and uneven mixing; the injection pressure is controlled within the range of 1.5 - 3 MPa, which not only ensures the uniformity of hydrogen injection but also takes into account the safety and economy of the system.

[0046] Meanwhile, through the above control, the mixing ratio of diesel-hydrogen dual fuel can also be optimized, the combustion stability can be improved, the power output of the internal combustion engine can be enhanced, and the diesel consumption can be reduced; in the dual-fuel combustion mode, soot particulate matter (PM) and nitrogen oxides (NOx) emissions can be reduced; combined with the exhaust gas recirculation (EGR) technology, the emissions of polluting gases can be further reduced to meet the requirements of more stringent environmental protection regulations.

[0047] The solid-state hydrogen storage device 2 is connected to the hydrogen nozzle 1 for supplying hydrogen to the hydrogen nozzle 1 and is provided with a heat exchange medium pipeline 4. The solid-state hydrogen storage device 2 is the core component for storing hydrogen, which is made of metal hydride materials or other solid-state hydrogen storage materials, and can realize the reversible adsorption and release of hydrogen under certain temperature and pressure conditions, with high hydrogen storage density and good safety performance. The solid-state hydrogen storage device 2 can be selected within a large range. Exemplarily, the solid-state hydrogen storage device 2 can be a solid-state hydrogen storage cylinder.

[0048] Figure 3 Schematically shows a structural schematic diagram of a solid-state hydrogen storage device involved in an embodiment of the present invention, as Figure 3 shown, the heat exchange medium pipeline 4 can be spiral and is arranged inside the solid-state hydrogen storage device 2.

[0049] The heat exchanger 3 is arranged on the exhaust pipe after the turbocharger of the internal combustion engine main body, and is used to heat the heat exchange medium by using the waste heat of the exhaust gas in the exhaust pipe and transport the heated heat exchange medium to the heat exchange medium pipeline 4 of the solid-state hydrogen storage device 2.

[0050] In an optional implementation manner, the heat exchanger 3 is a shell-and-tube heat exchanger. Figure 2 Schematically shows a structural schematic diagram of a heat exchanger in an embodiment of the present invention. As Figure 2 shown, the heat exchanger 3 can include an exhaust pipe sleeve 301 located inside and a shell 302 located outside, and there is a cooling medium cavity 303 between the exhaust pipe sleeve 301 and the shell 302; the exhaust pipe passes through the exhaust pipe sleeve 301, and the heat exchange medium flows through the cooling medium cavity 303.

[0051] In an alternative embodiment, a fan 5 is further provided on the outer wall of the housing 302 of the heat exchanger 3. The solid-state hydrogen storage device 2 can be disposed adjacent to the heat exchanger 3, and the side of the heat exchanger 3 where the fan 5 is provided faces the solid-state hydrogen storage device 2. The fan 5 is used to blow warm air by means of the waste heat of the exhaust gas in the exhaust pipe to assist in heating the solid-state hydrogen storage device 2, and can further improve the hydrogen desorption speed especially in a low-temperature environment.

[0052] A heat exchanger 3 is installed on the exhaust pipe after the turbocharger to utilize the waste heat of the internal combustion engine exhaust gas to heat the cooling medium (water or coolant); the heat exchanger 3 adopts a shell-and-tube design, and the material is selected from high-temperature resistant and corrosion-resistant stainless steel or nickel-based alloy; a fan 5 is installed outside the heat exchanger 3 to enhance the heat exchange efficiency through an air-cooling system, blow warm air to the outer surface of the solid-state hydrogen storage device, and assist in heating the solid-state hydrogen storage device, and transfer the waste heat of the exhaust gas to the solid-state hydrogen storage device more efficiently; the heated cooling medium is introduced into the internal spiral heat exchange medium pipeline 4 of the solid-state hydrogen storage device 2 through a pump to provide a stable heat source for the solid-state hydrogen storage device 2 and improve the hydrogen release efficiency and release stability of the solid-state hydrogen storage device 2.

[0053] The heat exchanger 3 constitutes a water-cooling system, and the fan 5 constitutes an air-cooling system. The water-cooling system is responsible for absorbing the heat of the exhaust gas and transferring the heat to the solid-state hydrogen storage device 2 through a pipeline; the air-cooling system further improves the heat exchange efficiency, especially for rapid heat dissipation under high-load conditions, to ensure the stability of the utilization of the waste heat of the exhaust gas; by combining the air-cooling and water-cooling systems and through precise heat transfer, the working temperature range (290K - 320K) of the solid-state hydrogen storage device 2 can be stably maintained.

[0054] In an alternative embodiment, a first temperature sensor 6 and a cooling medium flowmeter 7 can be provided on the infusion pipeline between the outlet of the heat exchanger 3 and the inlet of the heat exchange medium pipeline 4. A second temperature sensor 8 and a hydrogen flowmeter 9 can be provided on the hydrogen pipeline between the hydrogen outlet of the solid-state hydrogen storage device 2 and the hydrogen nozzle 1.

[0055] In an alternative embodiment, the diesel-hydrogen internal combustion engine system is further provided with a controller 10, and the controller 10 is electrically connected to the fan 5, the first temperature sensor 6, the cooling medium flowmeter 7, the second temperature sensor 8, and the hydrogen flowmeter 9.

[0056] The temperature sensor can monitor the temperature of the solid-state hydrogen storage device 2 and the cooling medium in real time; by adjusting the bypass valve of the heat exchanger 3, the rotation speed of the fan 5, and the flow rate of the cooling medium through the controller 10 (ECU), precise control of the temperature of the solid-state hydrogen storage device 2 can be achieved, and the hydrogen release efficiency can be prevented from being affected by overheating or insufficient temperature of the solid-state hydrogen storage device.

[0057] The present invention realizes diesel-hydrogen combustion through the following key technologies:

[0058] (1) The solid-state hydrogen storage material releases high-purity hydrogen under certain temperature and pressure conditions. By using the waste heat of the turbocharger exhaust gas and the heating method of the auxiliary fan, the desorption efficiency and stability of the hydrogen storage material are improved;

[0059] (2) A hydrogen nozzle is arranged at a position in the intake manifold close to the cylinder intake port. Hydrogen is injected into the supercharged air at a specific angle and pressure to form a uniform hydrogen-air mixture;

[0060] (3) The supercharged air enters the intake manifold after passing through the throttle valve, and is fully mixed with the injected hydrogen under the action of turbulence and then enters the cylinder to form a uniform mixture;

[0061] (4) Diesel is injected into the cylinder through the diesel nozzle at the top of the cylinder, and is further mixed with the uniformly mixed air-hydrogen mixture. Under high pressure and high temperature conditions, the mixture achieves rapid, uniform, and efficient combustion;

[0062] (5) The waste heat of the turbocharger exhaust gas heats the solid-state hydrogen storage device through a heat exchanger, further improving the release efficiency of the hydrogen storage material, and enhancing the heating effect through the auxiliary fan.

[0063] The interrelationships among the components of the diesel-hydrogen blended internal combustion engine system of the present invention are as follows:

[0064] Ⅰ. Solid-state hydrogen storage device, heat exchanger and fan: The solid-state hydrogen storage device is connected to the exhaust gas emission system through the liquid delivery pipeline of the heat exchanger. The heat exchanger uses the waste heat of the exhaust gas after the turbocharger to heat the heat transfer medium, and enhances the heating efficiency on the surface of the solid-state hydrogen storage device through the fan on the heat exchanger, thereby ensuring stable desorption of hydrogen;

[0065] Ⅱ. Hydrogen nozzle and intake manifold: The hydrogen nozzle is installed downstream of the intake manifold, at a position close to the intake port of each cylinder. The injected hydrogen is fully mixed with the supercharged air at an injection angle of 30° - 60°, ensuring uniform distribution into each cylinder;

[0066] Ⅲ. Turbocharger and heat exchanger: While the turbocharger increases the intake pressure, its exhaust pipe is connected to the heat exchanger, making full use of the waste heat resources of the internal combustion engine to improve the overall energy utilization efficiency;

[0067] Ⅳ. Hydrogen nozzle and controller: The injection parameters (such as pressure and hydrogen injection volume) of the hydrogen nozzle are controlled in real time by the controller, and the mixing ratio of hydrogen and air is optimized according to the working conditions of the internal combustion engine to ensure the best combustion effect.

[0068] The action processes or operation steps involved when the diesel-hydrogen blended internal combustion engine system of the present invention operates are as follows:

[0069] ① Supercharged air enters the intake manifold: After the air is supercharged by the turbocharger, it enters the intake manifold through the throttle valve;

[0070] ② Hydrogen desorption and injection: The solid-state hydrogen storage device releases hydrogen under the combined heating of the heat exchanger and the fan. The hydrogen is transported through the desorption channel to the hydrogen nozzle and is injected into the intake manifold at a pressure of 1.5 - 3 MPa and an injection angle of 30° - 60° by the nozzle.

[0071] ③ Mixture formation: Hydrogen and supercharged air are mixed at a position downstream of the intake manifold near the cylinder intake port, and a uniform hydrogen-air mixture is formed under the action of turbulence.

[0072] ④ Mixture combustion: After the mixture enters the cylinder, it participates in combustion together with the injected diesel fuel. The high combustion rate of hydrogen significantly improves the combustion efficiency and reduces the incompleteness of diesel combustion.

[0073] ⑤ Exhaust gas waste heat utilization: The exhaust gas emitted by the engine heats the heat transfer medium through the heat exchanger. The hot heat transfer medium is transported to the solid-state hydrogen storage device through the infusion pipe, and at the same time, the fan heats the surface of the solid-state hydrogen storage device.

[0074] ⑥ Temperature control and safety monitoring: The entire system monitors the solid-state hydrogen storage device and the desorption process in real time through temperature control sensors and pressure sensors. The controller adjusts the heating power and hydrogen release rate according to the sensor feedback data to ensure the safe and efficient operation of the system.

[0075] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
