Source-checked against supplied Yuchai workbook 玉柴动力v25机械泵.xlsx, sheet YCD4V22D(V25): 1800 rpm: rated engine 33 kW, standby engine 36.5 kW at 1800 rpm; matched genset 常用：24 / 备用：26.4 kW (model cell F6; rating cells F24, F25, F44). Engine rated power is labelled 额定 in the source, not explicitly ISO prime duty. Catalogue power_kw is the highest listed rated engine output. All calibration variants are retained here; frequency-specific prime/standby/electrical fields remain blank because the workbook does not explicitly specify frequency or ISO prime duty. No emissions certification inferred from workbook title. Production status is unknown. Discontinued is the user-authorized catalogue classification (2026-10-21 import), not manufacturer-confirmed cessation; no production-end year is asserted.
