Yuchai YCD4A33H6-120
Source-checked against supplied Yuchai workbook 玉柴动力T3参数.xlsx, sheet YCD4A33H6(V31): 1800 rpm: rated engine 80 kW, standby engine 88 kW at 1800 rpm; matched genset 常用：65 / 备用：72 kW (model cell E6; rating cells E23, E24, E44). 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.
