The serialized new energy locomotive can meet the green transformation needs of railway transportation in multiple fields such as steel, metallurgy, petroleum, chemical, mining, coal, power, and ports, making it an ideal choice for replacing outdated diesel locomotives.
Diverse: The locomotive is designed and developed based on the concepts of platformization, standardization, and modularization, enabling "menu-style" configuration. The power class covers 1000 kW to 2000 kW, with three selectable power options: "diesel engine + power battery," "power battery," and "hydrogen fuel cell + power battery." Each functional module of the locomotive is assembled in parallel and installed independently, enabling efficient customization and agile delivery.
Green: The locomotive features green characteristics such as low emissions and low energy consumption. Compared with outdated diesel locomotives, the "diesel engine + power battery" locomotive can achieve an 83% reduction in carbon monoxide emissions, a 73% reduction in hydrocarbons, and a 45% reduction in nitrogen oxides. The "power battery" and "hydrogen fuel cell + power battery" configurations can achieve zero emissions.
Intelligent: The locomotive adopts microcomputer control and reserves interfaces for autonomous driving functions. By configuring systems such as video monitoring, environmental perception, and collision warning, remote control and autonomous driving can be realized. The locomotive can be equipped with a PHM (Prognostics and Health Management) system to achieve fault detection, condition monitoring, and life prediction for the locomotive and key components, effectively extending locomotive maintenance intervals.
Reliable: The locomotive features vehicle-level and component-level safety protection for the power battery and hydrogen fuel systems, comprehensively ensuring the safety of the core power sources. The main components of the locomotive are carried over from mature models, achieving stable performance and safety and reliability. The structural strength of key load-bearing components such as the underframe and bogies has been comprehensively optimized and enhanced. Multiple power sources and power battery packs serve as mutual redundancy, enabling the locomotive failure rate to be reduced by more than 10% compared with existing locomotives.
Economical: The locomotive adopts a high-efficiency traction converter system, with maximum starting tractive effort exceeding 510 kN, a 17% increase in tractive effort compared with the same class. Through optimal hybrid power control technology, the locomotive ensures that the diesel engine always operates at the optimal economical speed. The application of regenerative braking energy feedback technology enables the "diesel engine + power battery" locomotive to achieve a fuel saving rate of more than 45%, with effective improvement in main transmission efficiency. In addition, the simplification and unification rate of key locomotive components exceeds 80%, enabling interchangeability and commonality of parts across different models, further reducing spare parts varieties and lowering maintenance costs.
Comfortable: Compared with outdated diesel locomotives, the serialized new energy locomotive provides a more comfortable working environment for drivers and passengers. The net space of the driver's cab has increased by 40%, creating an extra-large "living space"; the lookout area has increased by 79%, providing an extra-large field of view. The use of power batteries and hydrogen fuel cells effectively reduces noise duration, and the noise level inside the driver's cab of the "diesel engine + power battery" locomotive can be reduced to below 70 dB.
