小松 D51EX-22 推土机以其卓越的性能和可靠性，在土方工程领域备受青睐。其强劲的动力核心离不开一套高效、稳定的燃油供给系统。燃油管路作为该系统的“血管”，负责将燃油从油箱精准输送到发动机的各个关键部件。本文将深入剖析小松 D51EX-22 推土机的燃油管路系统，并提供详细的产品信息，帮助用户更好地理解和维护设备。

The Komatsu D51EX-22 bulldozer is a trusted workhorse in earthmoving operations, highly valued for its superior performance and reliability. At the core of its powerful engine lies an efficient and stable fuel supply system. The fuel line, acting as the "vascular system," is responsible for precisely delivering fuel from the tank to the engine's critical components. This article will provide an in-depth analysis of the Komatsu D51EX-22 bulldozer's fuel line system and offer detailed product information to help users better understand and maintain their equipment.

该推土机的燃油管路系统设计精良，由高压燃油管、低压回油管、燃油滤清器管等多个核心部件组成。高压燃油管（或称高压油管）承载着将高压燃油从燃油泵输送至喷油器的重任，其材质和密封性能至关重要。任何微小的泄露都可能影响发动机的正常工作，甚至引发安全隐患。低压回油管则负责将多余燃油回流至油箱，确保系统压力稳定。燃油滤清器管路则连接着燃油泵和滤清器，有效过滤杂质，保护发动机免受损害。

The bulldozer's fuel line system is meticulously designed, consisting of several key components, including high-pressure fuel lines, low-pressure return lines, and fuel filter lines. The high-pressure fuel line is critical for carrying high-pressure fuel from the fuel pump to the injectors; its material and sealing integrity are of paramount importance. Even a minor leak can compromise engine performance and pose safety risks. The low-pressure return line routes excess fuel back to the tank, ensuring stable system pressure. The fuel filter line connects the fuel pump to the filter, effectively removing impurities and protecting the engine from damage.
