- Weichai Power (HKG:2338) announced on July 10, 2026 that its self-developed WP15 hydrogen direct-injection heavy-duty engine passed full China VI vehicle emission certification on July 3, 2026 at the CATARC Automotive Test Center in Tianjin.
- The certification is the first time a heavy-duty hydrogen internal combustion engine, in China or globally, has met the country's stringent China VI emission standard.
- Testing covered the complete national heavy-duty engine emission test cycle — cold start, low-speed idling, high-speed full-load, and transient variable-load conditions — verifying the engine's emission performance, reliability and stability under real-world operating scenarios.
- 潍柴动力（HKG:2338）于2026年7月10日宣布，其自主研发的WP15氢直喷重卡发动机于7月3日在天津中国汽车技术研究中心（CATARC）通过了中国Ⅵ排放全项认证。
- 此次认证使其成为全球及中国首款达到中国Ⅵ排放标准的重型氢内燃机。
- 认证测试涵盖国家重型发动机排放标准要求的完整工况循环，包括冷启动、低速怠速、高速满负荷及瞬态变负荷等场景，验证了发动机在真实运行条件下的排放性能、可靠性与稳定性。
