China has not directly introduced or operated the original ‌GEVO series locomotives (General Electric Evolution series diesel locomotives of the United States) ‌. The main high-power diesel locomotives widely used in China 's railways are the ‌ "harmony" series diesel locomotives (HXN series) ‌, which are based on imported technology and localized.
Youdaoplaceholder0 main domestic models ‌ :
China widely uses domestically manufactured Harmony series diesel locomotives, such as models equipped with ‌4400 kW‌ ‌16V265H diesel engine ‌.
This diesel engine model (265H) indicates that its technical origin is closely related to GE's 265 series (i.e., the core of the EVO/GEVO series), and it is the result of China 's technology introduction, digestion, absorption and re-innovation ‌.
Youdaoplaceholder0 Key parameters ‌ : maximum speed 120 km/h, maximum starting traction force 620 kN, continuous traction force 578 kN, emissions comply with the US EPA Tier 2 standard ‌.
At present, the number of diesel locomotives in China is approximately ‌ 7,800 ‌ units. The HXN series is the core component, but the specific model data has not been disclosed.
