[0001] The present invention relates to the technical field of hydrogen engine boost system design, and in particular, to a hydrogen engine boost system and an engine having the same. Background Art

[0002] At present, due to the need for performance control of the hydrogen system, relatively high requirements are put forward for the minimum working pressure of hydrogen. When the actual pressure of hydrogen is lower than the minimum working pressure, the use requirements of the hydrogen fuel engine cannot be met. Therefore, for the hydrogen cylinder, the internal pressure lower than this value means that the remaining hydrogen cannot be utilized, reducing the hydrogen utilization rate and resulting in frequent hydrogen refueling of the vehicle.

[0003] In the prior art, the pressure reducing valve of the hydrogen fuel engine system is a constant pressure reducing valve, which has the defect of poor matching flexibility. At the same time, once the pressure of the constant pressure reducing valve is lower than the set pressure, the hydrogen fuel engine cannot operate normally. Users can only choose to return to the hydrogen refueling station for hydrogen refueling, reducing the hydrogen utilization efficiency. Summary of the Invention

[0010] Furthermore, the hydrogen energy engine boost system further includes: a controller, which is electrically connected to the three-way valve, the water pump branch valve, and the hydrogen concentration sensor.

[0036] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0037] Combined Figure 1 and Figure 3 As shown, according to a specific embodiment of the present application, a hydrogen engine boost system is provided.

[0038] The hydrogen engine boost system includes a hydrogen storage device 10, a three-way valve 20, an injector 30, and a boosting device 40. The input port of the three-way valve 20 is communicated with the output end of the hydrogen storage device 10. The injector 30 is communicated with the first output port of the three-way valve 20. The input end of the boosting device 40 is communicated with the second output port of the three-way valve 20. The output end of the boosting device 40 is communicated with the injector 30. The boosting device 40 is used to pressurize the hydrogen passing through the inside of the boosting device 40. Among them, the three-way valve 20 has a first working position in which only the first output port is communicated with the hydrogen storage device 10, and the three-way valve 20 has a second working position in which only the second output port is communicated with the hydrogen storage device 10.

[0039] Applying the technical solution of this embodiment, the hydrogen engine boosting system includes a hydrogen storage device 10, a three-way valve 20, an injector 30, and a boosting device 40. By boosting hydrogen through the boosting device 40, the boosting system can still enter the injector 30 at a relatively high pressure when the hydrogen pressure in the hydrogen storage device 10 is lower than a set value such as the rail demand pressure. By setting the three-way valve 20, the hydrogen engine boosting system can reasonably switch to different hydrogen transmission paths according to the hydrogen pressure situation inside the hydrogen storage device 10, so that the boosting system has a high hydrogen utilization efficiency in various situations and prevents the situation where there is still some hydrogen stored in the hydrogen storage device 10 but cannot be used. Combining the technical solution of this application effectively solves the problem of low hydrogen utilization rate of the hydrogen engine boosting system in the prior art.

[0040] Furthermore, the hydrogen engine boosting system further includes a hydrogen cooling device 50. The input end of the hydrogen cooling device 50 is connected to the output end of the boosting device 40. The output end of the hydrogen cooling device 50 is connected to the injector 30. The hydrogen cooling device 50 is used to cool the boosted hydrogen to prevent the risk of pre-ignition when the high-temperature hydrogen enters the rail. Preferably, the hydrogen cooling device 50 controls the hydrogen temperature below 85°C.

[0041] As Figure 1 shown, a cooling water jacket is provided on the surface of the boosting device 40. The cooling water jacket is connected to the water tank through a water pump branch valve 60. The cooling water jacket is used to take away the heat generated during the operation of the boosting device 40.

[0042] Furthermore, the hydrogen engine boosting system further includes a pressure reducer 70. The input end of the pressure reducer 70 is connected to the output end of the hydrogen storage device 10. The output end of the pressure reducer 70 is connected to the first output port. Setting the pressure reducer 70 can reduce the high-pressure gas inside the hydrogen storage device 10 to a suitable pressure and then enter the rail.

[0043] Optionally, a hydrogen concentration sensor is provided at the output end of the pressure reducer 70.

[0044] Furthermore, the hydrogen engine boosting system further includes a controller 80. The controller 80 is electrically connected to the three-way valve 20, the water pump branch valve 60, and the hydrogen concentration sensor. The controller 80 is used to control the three-way valve 20 to switch between the first working position and the second working position according to the hydrogen concentration collected by the hydrogen concentration sensor, and to control the water pump branch valve 60 to close or open according to the hydrogen concentration.

[0045] In an alternative embodiment, the hydrogen engine boost system further includes a controller 80. The controller 80 is electrically connected to the three-way valve 20 and the water pump bypass valve 60. A pressure sensor is provided at the output end of the pressure reducer 70. The controller 80 is configured to control the switching of the three-way valve 20 between the first working position and the second working position according to the hydrogen pressure collected by the pressure sensor, and to control the closing or opening of the water pump bypass valve 60 according to the hydrogen pressure. Preferably, the controller is an ECU. The ECU judges the boost system by monitoring the pressure at the outlet of the pressure reducer. When the pressure is higher than the rail demand pressure, the hydrogen boost pump does not work, and the pressure reducer directly passes through the three-way valve 20 to the rail end for constant pressure operation. When the cylinder pressure is equal to or less than the rail demand pressure, the pressure reducer is connected to the hydrogen boost pump to boost the hydrogen. At the same time, the water pump bypass valve 60 is opened to cool the boosted hydrogen, so as to meet the requirements of the hydrogen fuel engine for hydrogen fuel.

[0046] Optionally, the boosting device 40 is a boosting piston pump.

[0047] As Figure 3 shown, the hydrogen engine boost system further includes a direct passage branch 100. The inlet end of the direct passage branch 100 is connected to the hydrogen storage device 10, and the outlet end of the direct passage branch 100 is connected to the injector 30. A direct passage solenoid valve 101 is provided on the direct passage branch 100. The direct passage solenoid valve 101 is electrically connected to the controller 80. The controller 80 is configured to control at least one of the direct passage solenoid valve 101 and the three-way valve 20 to be in a working state according to the hydrogen pressure of the hydrogen storage device 10. By adopting the technical solution of this embodiment, the hydrogen injection path can be adaptively adjusted according to the hydrogen storage device 10, and on the basis of meeting the vehicle power requirements, the energy utilization efficiency of the hydrogen storage device 10 can be improved. In combination with this embodiment, a control method for the hydrogen engine boost system is also provided. A pressure sensor is provided in the hydrogen storage device 10. When the pressure value detected by the pressure sensor is greater than the first preset value, the controller 80 controls the solenoid valve 91 and the direct passage solenoid valve 101 to close and controls the three-way valve 20 to be in the first working position. When the pressure value detected by the pressure sensor is greater than the second preset value, the controller 80 controls the solenoid valve 91 to close, the direct passage solenoid valve 101 to open, and controls the three-way valve 20 to be in a stopped working state. When the pressure value detected by the pressure sensor is greater than the third preset value, the controller 80 controls the solenoid valve 91 to close, the direct passage solenoid valve 101 to close, and controls the three-way valve 20 to be in the second working position. When the pressure value detected by the pressure sensor is greater than the fourth preset value, the control solenoid valve 91 is opened, the direct passage solenoid valve 101 is closed, and the three-way valve 20 is controlled to be in the second working position. Among them, the first preset value, the second preset value, the third preset value, and the fourth preset value are set to gradually decrease.

[0048] Actually, when the pressure value detected by the pressure sensor is greater than the first preset value, the hydrogen pressure in the hydrogen storage device 10 is relatively high. Therefore, after being decompressed by the pressure reducer 70, the hydrogen directly leads to the injector 30, enabling the rapid decompression and use of hydrogen. When the pressure value detected by the pressure sensor is greater than the second preset value and less than the first preset value, the hydrogen pressure in the hydrogen storage device 10 is appropriate, and it directly leads to the injector 30 through the direct connection branch 100, effectively reducing the frictional loss of hydrogen along the way. When the pressure value detected by the pressure sensor is greater than the third preset value and less than the second preset value, the hydrogen pressure in the hydrogen storage device 10 is relatively low. At this time, the hydrogen is pressurized by the pressurization device 40 and then enters the injector 30, effectively meeting the hydrogen demand of the vehicle. When the pressure value detected by the pressure sensor is greater than the first preset value, the hydrogen pressure in the hydrogen storage device 10 is very low, and the auxiliary hydrogen cylinder 90 is used to supply hydrogen to ensure that the hydrogen demand of the vehicle is met. By adopting the technical solution of this embodiment, the hydrogen engine boost system realizes the adaptive switching of the hydrogen transfer path, and can meet the vehicle power performance requirements under various different hydrogen storage scenarios.

[0049] As Figure 2 shown, the hydrogen engine boost system further includes an auxiliary hydrogen cylinder 90. The output end of the auxiliary hydrogen cylinder 90 is connected to the injector 30, and a solenoid valve 91 is provided at the output end of the auxiliary hydrogen cylinder 90. The solenoid valve 91 is electrically connected to the controller 80. Such a setting enables the hydrogen engine boost system to avoid the safety problem of the pressurized hydrogen directly entering the air rail when the hydrogen cooling device 50 fails to work. That is, when the hydrogen cooling device 50 fails to work, the pressurization device 40 is stopped from being used, and the solenoid valve 91 of the auxiliary hydrogen cylinder 90 is controlled to open.

[0050] Furthermore, a temperature sensor is provided at the output end of the pressurization device 40. The controller 80 is configured to control the solenoid valve to be in an open state when detecting that the temperature of the hydrogen output by the pressurization device 40 is higher than the preset value.

In one instance, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices through a base station and thus communicate with the Internet.
