Description

Onboard ammonia fuel supply integrated device with bottom-mounted protective structure Technical Field

[0001] This utility model relates to the field of fuel supply device technology, and in particular to an integrated vehicle-mounted ammonia fuel supply device with a bottom-mounted protective structure. Background Technology

[0002] Ammonia is a carbon-free fuel that does not produce carbon dioxide during combustion, making it an ideal fuel for reducing carbon emissions in engines. Its combustion does not produce carbon deposits or pollutants, and it reduces wear on engine parts, significantly improving the lubrication system and extending engine life. Precise control of ammonia-diesel blended fuel engines is an effective way to achieve stable combustion. Existing technologies focus on improving and innovating system structures to achieve stable operation of engines with ammonia blended in specific proportions.

[0003] Currently, similar to ammonia fuel supply systems, LNG fuel supply systems or methanol fuel supply systems employ a separate arrangement of LNG / methanol tanks, pressure reducing valves, filters, etc., which are then connected in series using metal pipelines to form a complete supply system. This arrangement is not compact enough and occupies a large amount of space on the side of the vehicle frame.

[0004] To address the aforementioned technical shortcomings, a solution is proposed that utilizes a modular, open-structure layout to install the entire ammonia supply system on one side of the longitudinal beam of the vehicle chassis. This design is simple, compact, and easy to maintain. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated vehicle-mounted ammonia fuel supply device with a bottom-mounted protective structure, in order to solve the problem of the scattered layout and large occupation of the side space of the vehicle caused by the separate arrangement of existing fuel supply systems similar to ammonia fuel supply systems.

[0006] The objective of this utility model can be achieved through the following technical solution: an integrated vehicle-mounted ammonia fuel supply device with a bottom-mounted protective structure, comprising a liquid ammonia storage module, a vaporization module, and a pressure stabilizing module. The input end of the vaporization module corresponds to the liquid outlet port of the liquid ammonia storage module. The vaporization module is connected to the pressure stabilizing module and is connected to the engine through the pressure stabilizing module and the fuel injection system. The vaporization module achieves a stable supply of gaseous ammonia to the engine through the pressure stabilizing module and the fuel injection system.

[0007] Preferably, the liquid ammonia storage module includes an ammonia cylinder assembly, the ammonia cylinder assembly is equipped with a bottom protective structure for modular layout near the vehicle body, and the front end of the ammonia cylinder assembly is provided with a liquid ammonia filling port.

[0008] Preferably, the bottom protective structure includes a bottom support disposed at the bottom of the ammonia cylinder assembly, a ring support installed on the bottom support in contact with the bottom side of the ammonia cylinder assembly, and a hoop ring covering the outer surface of the ammonia cylinder assembly installed between the upper ends of the ring support.

[0009] Preferably, the vaporization module includes a liquid ammonia solenoid valve connected to the ammonia cylinder filling port, and the liquid ammonia solenoid valve is connected to a vaporizer.

[0010] Preferably, the pressure stabilizing module includes an ammonia filter connected to the carburetor, the ammonia filter being sequentially connected to a pressure stabilizing valve and an ammonia solenoid valve, and the ammonia solenoid valve being connected to the engine fuel pretreatment system.

[0011] Preferably, the vaporization module further includes an air filter connected to a compressed air tank for vehicle braking, and an air solenoid valve is connected to the front end of the air filter.

[0012] Preferably, the bottom protective structure further includes a side platform disposed on one side of the ammonia cylinder assembly, with a rod support installed on the lower side of each side platform, and a side base plate installed on the lower side of the rod support. The side base plate and the rod support are used together for supporting and installing the vaporization module and the pressure stabilizing module.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model can ensure that the vibration frequency of each component in the device is consistent through the integrated integrated structure design, thereby improving the durability of the vehicle ammonia fuel supply system. Based on adapting to the physical and chemical properties of ammonia fuel, it achieves an integrated compact structure layout with the airtight structure design of the pipeline, reducing the space occupied on the side of the vehicle frame, and the structure is simple and easy to maintain.
