AI Technical Summary

Technical Problem

The existing separate and individual layout of ammonia fuel supply systems results in a scattered layout, occupies a large amount of space on the side of the vehicle, and lacks an effective protective structure.

Method used

The vehicle-mounted ammonia fuel supply integrated device with a bottom-mounted protective structure includes a liquid ammonia storage module, a vaporization module, and a pressure stabilizing module. The pressure stabilizing module is connected to the engine through the fuel injection system. Combined with the protective structure composed of a bottom support, ring support, and side bottom plates, it achieves modular layout and stable connection.

Benefits of technology

It achieves a compact, integrated structural layout, reduces the space occupied on the side of the chassis, improves the system's durability and ease of maintenance, and provides effective protection against the risk of collisions and scrapes.

Abstract

The utility model belongs to the technical field of fuel supply devices, and particularly discloses a vehicle-mounted ammonia fuel supply integrated device adopting a bottom protection structure, which is used for solving the problems that the layout is scattered and large side space of an automobile is occupied due to a separated independent arrangement mode adopted by an existing fuel supply system similar to an ammonia fuel supply system. Through the integrated structural design, it can be ensured that the vibration frequencies of all parts in the device are kept consistent, so that the durability of the vehicle-mounted ammonia fuel supply system is improved, on the basis of adapting to the physicochemical characteristics of ammonia fuel, the pipeline airtight structural design is matched to achieve the integrated compact structural layout, the occupied space of the side face of a vehicle frame is reduced, and the service life of the vehicle is prolonged. The structure is simple and convenient to maintain; and through a bottom protection structure composed of the bottom support, the ring support, the side bottom plate and the rod support, stable connection with the longitudinal beam side of the automobile chassis can be effectively provided, the bottom anti-rubbing function can be added, and reliable protection can be achieved even on a non-paved road surface or a bad bumpy road surface.
